BERGRIVIER MUNICIPALITY B I O D I V E R S I T Y R E P O R T | 2 0 10 ENHANCING URBAN NATURE THROUGH A GLOBAL NETWORK OF LOCAL GOVERNMENTS The Local Action for Biodiversity (LAB) Programme began as a 3 year project that was developed by ICLEI - Local Governments for Sustainability, International Union for the Conservation of Nature (IUCN) and other partners, and was initiated by the City of Cape Town, and supported by the eThekwini Municipality (Durban). ICLEI is an international association of local governments and national and regional local government organizations that have made a commitment to sustainable development. LAB is ICLEI's global biodiversity programme, which aims to assist local governments in their efforts to conserve and sustainably manage biodiversity. Local Action for Biodiversity involves a select number of cities worldwide and focuses on exploring the best ways for local governments to engage in urban biodiversity conservation, enhancement, utilization and management. The Programme aims to facilitate understanding, communication and support among decisionmakers, citizens and other stakeholders regarding urban biodiversity issues and the need for local action. It emphasizes integration of biodiversity considerations into planning and decision-making processes. Some of the specific goals of the programme include demonstrating good practice urban biodiversity management; provision of documentation and development of biodiversity management and implementation tools; access to technical biodiversity expertise; sourcing funding from national and international agencies for biodiversity-related development projects; profiling LAB local governments; and increasing global awareness of the importance of biodiversity at the local level. The Local Action for Biodiversity Programme is hosted within the ICLEI Africa Secretariat at the City of Cape Town, South Africa. For more information, please visit www.iclei.org/lab. MAYOR’S MESSAGE The Bergrivier Municipality (BRM) is proud to be part of the new global urban biodiversity initiative Local Action for Biodiversity (LAB) programme which was launched by ICLEI Local Governments for Sustainability in 2006. The programme aims to facilitate the understanding and communication among decision makers, citizens and other stakeholders regarding biodiversity issues and the need for local action. The BRM falls within the Cape Floral Kingdom, which is a global biodiversity hotspot. The presence of natural features such as; 21 vegetation types with many rare and endangered plant species; the Berg River Estuary, which is rated the 3rd most important estuary in South Africa; many rare and endemic vertebrate species such as the Berg River redfin, and the rugged Groot Winterhoek Wilderness, which is part of the Cape Floral Region World Heritage Site, contribute to the biodiversity assets of the BRM. These natural areas contain valuable ecological systems delivering environmental services and natural capital goods that are critical for the functioning of the earth's life support systems and the economy. Biodiversity plays a very important role in underpinning and sustaining the livelihoods of urban and rural people of the BRM. Biodiversity gives the BRM its unique character and the conservation of its uniqueness can translate into a powerful economic driver through responsible tourism. It is therefore absolutely essential that the BRM as an environmental steward manage and conserve this wealth of biodiversity. This report profiles the variety and state of the biodiversity assets within the BRM and the collaborative efforts that government and civil society have launched to conserve and manage this globally significant asset. This document will be used by staff and other stakeholders as a baseline document for the successful planning and implementation of the Bergrivier LAB programme into the future. The Council of the Bergrivier Municipality is committed to sustainable development goals through continuous networking and learning from local and global institutions and authorities.The conservation of biodiversity and the ecosystem goods and services that it supplies are a cornerstone of sustainable development. It is in everyone's interest that biodiversity is fully integrated into planning and decision making in the BRM.

It represents a critical starting point: a status quo assessment of biodiversity and its management in each LAB city. Each biodiversity report covers four key themes*, namely: 3 3 3 3 Ecology; Governance; Integration; Participation. The LAB participants' biodiversity reports in the past have been drawn upon by the LAB Coordination Team to contribute significant and useful information for the compilation, of the Local Action for Biodiversity Guidebook: Biodiversity Management for Local Governments. The LAB Guidebook is a practical guide and contains good practice theory and examples, principles, strategies etc. for use by cities to better manage local biodiversity. The LAB Guidebook will in turn contribute towards further steps in the LAB process. The five steps in the LAB process are as follows: Step 1: Development of a biodiversity report that documents the current state of biodiversity and its management within each local government; Step 2: Ensuring long-term commitment by political leaders to sustainable biodiversity management through the formal signing of the internationally recognised Durban Commitment; Step 3: Development of a long-term biodiversity strategy and action plan (LBSAP) that will include commitments to biodiversity plans and integration within broader city plans; Step 4: Formal acceptance and approval of LAB participants' LBSAP; Step 5: Implementation of three on-the-ground biodiversity interventions or projects by the end of the three-years. The biodiversity reports create a unique opportunity for profiling the importance of urban biodiversity, and innovation in its management, on a global scale. They are the foundation not only of the long-term plans that each city will develop to enhance, protect and develop their urban biodiversity, but also collectively form the basis for the development of LAB as a highly effective global urban biodiversity programme. These reports will also serve to inform all local government staff (and others) about local biodiversity. The aim of the report is to highlight the importance of biodiversity features in the Bergrivier Municipality. 7 6 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 EXECUTIVE SUMMARY The Bergrivier Municipality (BRM) is situated within the jurisdictional district of the West Coast District Municipality and covers an area of 4 407 km². It is home to an estimated 55 999 primarily rural people, many of them poor and unskilled. The biodiversity features within the BRM are of global conservation significance and the Groot Winterhoek Wilderness which is a Cape Floral Region World Heritage Site. The environment has been occupied by hominins and later by humans for at least 1 million years and has a rich archaeological heritage. Commercial agriculture dominates and is the primary economic activity and driver of habitat transformation and loss of biodiversity. However ecotourism is recognised as the most important economic driver in increasing revenue for the municipality and as a means of delivering livelihood benefit to the rural community. The BRM is part of the Cape Floristic Region (CFR), the only floristic region in the world to occur wholly within the borders of a single country and is one of the 34 globally identified biodiversity hotspots. It is home to 9000 plant species, 70% of which are unique to the floral kingdom. The municipality is characterised by a great diversity of soils, altitudinal and rainfall gradients and as a result is home to an astonishing variety of life. Twenty-one vegetation types occur within the BRM, one of which, Piketberg Sandstone Fynbos, is endemic to the municipality. The lowland areas and associated vegetation types have been heavily impacted by human occupation and activity. The result has been that they are some of the most threatened ecosystems in the South Africa and require concerted effort if they are to be conserved. The BRM is also home to a large variety of vertebrates and invertebrates. The larger ungulates are however now locally extinct. The Verlorenvlei redfin is unique to that river system, and the Sout River has its own species of Galaxia. Particularly 2 important is the 9000 km Berg River catchment that feeds the Berg River Estuary which is regarded as the 3rd most important estuary in South Africa and the catchment of the Verlorenvlei Wetland which is a RAMSAR site. The hotter drier predictions of climate change for the West Coast could have far reaching impacts on these systems in future. There is a great diversity of wetland habitats throughout the BRM all of which are under threat to a greater or lesser degree, once again the lowland systems in particular are highly threatened. Terrestrial and aquatic ecosystems have been identified as Critical Biodiversity Areas and Critical Ecological Support Areas in the BRM. It is of utmost importance that these areas are conserved and that the desired management objective for these areas are met by the administrators of the BRM. Great strides have already been taken in conserving the rich biodiversity heritage of the BRM with 48 727 ha's formally conserved in Provincial Nature Reserves and in stewardship agreements and a further 46 073 ha's committed to conservation on a voluntary basis. The BRM recognises that the well-being of every human population in the world is fundamentally and directly dependent on ecosystem services. The development of a dedicated strategy for biodiversity conservation in the BRM is a key challenge that must be addressed. The BRM realises that it is not alone in this endeavour but that a significant opportunity exists to partner and work with the many projects, civil society and institutional structures, industry initiatives, NGO's and government departments and agencies that are actively engaged in addressing the challenges to biodiversity conservation and sustainability within the municipal boundaries. Through this collaboration the municipality aims to achieve its mission of delivering cost-effective, sustainable services with a well represented army of employees who are motivated to stimulate local economic development as well as environmentally sensitive development through transparent decision making based on sound management principles within the ambit of unique character and cultural, historical heritage. 7 7 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 INTRODUCTION INTRODUCTIONAND ANDBACKGROUND BACKGROUND 1.1 LOCATION The Bergrivier Municipality (BRM) is situated within the jurisdictional district of the West Coast District Municipality in the Western Cape. It covers more than 4 407 km² and is surrounded by four other Municipalities namely Cederberg to the north, Swartland to the south, Saldanha Bay to the west and Witzenberg (Cape Winelands District Municipality) to the east. The Municipality aims to meet the needs of the LOCALITY MAP OF BERGRIVIER MUNICIPALITY community and to provide services to the urban settlements of Redelinghuys, Eendekuil, Aurora, Velddrif, Porterville, Piketberg, Dwarskersbos, Laaiplek, G o e d v e r w a c h t a n d W i t t e wa t e r . Piketberg serves as the administrative centre for the municipality. These towns are respectively between 100 and 150 kilometres to the north of the City of Cape Town. Natural features such as the Atlantic Ocean to the west, the Groot Winterhoek Mountains to the east, the Berg River to the south and the Verlorenvlei to the north define the boundary of the BRM. Some of these features are of global conservation significance and include the Berg River Estuary which is recognised internationally as a Ramsar site and the Groot Winterhoek Wilderness which is part of the Cape Floral Region World Heritage Site. 8 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 1.2 HISTORY The archaeological importance of the West Coast is well established. Archaeological and historical evidence indicates that the West Coast of South Africa has been occupied by hominins, and later humans, since the Early Stone Age (more than 1 million years ago) through to the Middle Stone Age and Later Stone Age, right up to the recent arrival of early Trekboers in the 18th century. By far the greatest number of archaeological sites are those which relate to the ancestry of the San and Khoekhoen. Some of these sites have been radiocarbon dated and are at least 5000 years old. This is an area that has been occupied by modern humans for an extended period of time. Subsequent research has now shown that people have been exploiting coastal resources along this portion of the West Coast for the last 120 000 years (Kaplan pers com). Commercial agricultural land use dominates the rural landscape of the BRM. From the records of early Dutch travellers, it has been established that the hunter-gatherer settlements were ephemeral, as that these peoples were primarily nomadic, moving in response to the availability of food. Most early explorers mentioned the large numbers of abandoned windbreaks, which seem to have been occupied for very short periods of time, constructed by these nomads. Small numbers of stone artefacts, potsherds and ostrich eggshells have been recorded in a number of deflation hollows that are located north of the Berg River between the river and Rocher Pan. Further inland of Velddrif scatters of Later Stone Age tools, ostrich eggshell, pottery and colonial era artefacts have been found in wind deflation hollows and agricultural lands north of the Berg River (Kaplan pers com). South of Velddrif, Aurora and Piketberg, the landscape changes dramatically, this wide region has been transformed for intensive wheat production, but even within these highly modified landscapes, archaeological occurrences have still been documented. Very little archaeological research has been done in the area south of Aurora. Research along the drainage line of the Bergrivier, between Paarl and Porterville, has documented Middle and Early Stone occurrences. Bushman rock paintings occur in the mountains above Aurora and the adjacent Piketberg Mountain. There are also historical accounts of a Khoekhoen group known as the `Kogokwas', whose presence in the Aurora area, along with several other groups living around the Piketberg Mountains, was recorded in the 1660's (Kaplan pers com). South of Hopefield and west of Moorreesburg, older archaeological material dating from the Middle and Early Stone Ages has been found in areas where agricultural activities such as wheat farming are pursued. These materials have been unearthed by farmers while ploughing their lands in preparation for planting. Recent research has also shown that Khoekhoen herder encampments are archaeologically `visible' in these highly transformed landscapes. Small scale sand mining has also resulted in the exposure of previous land surfaces, on which older ESA and MSA material is also found (Kaplan pers com). The Groot Winterhoek region is known for its large number of rock paintings, particularly those depicting colonial imagery. Rock paintings record the remarkable artistic achievement of the indigenous San of Southern Africa, who created them for religious purposes as part of a changing cultural tradition that persisted for over 20 000 years. The Groot Winterhoek was also unusual in terms of early Cape history, in that - unlike in many other areas from which the Khoisan quickly disappeared there was sustained contact in the region between remnants of the Khoisan and colonists throughout the eighteenth century (Kaplan pers com). 9 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 EXTINCT LARGE UNGULATES Governor Simon van der Stel's expedition to the copper mountains in Namaqualand in 1681 called Verlorenvlei the 'Zeekoejen-valey', referring to the many hippopotami they observed. The San name for the river was 'Quaecoma' (a lost or forlorn marsh) and the Dutch then translated that to 'Verloren Vallei'. Van der Stel's diary also revealed the presence of black rhinos in the Piketberg area, with a record of being chased by one while out hunting. Some of the many rock drawings in the area left by Khoisan and other indigenous people. By the start of the 1800's many Colonists had established fisheries and sent their salted fish as far as Tulbagh and Goudini. This inland trade of salted and dried fish supports the inhabitants of the coast. In 1806 the Swartland and Piketberg regions began to develop as the cereal production region of the Cape Colony. By the 1830's ships and cutters were plying an important local trade route as they transported grain and other commodities between Cape Town and Velddrif and further into the Sandveld. 1.3 THE PEOPLE In 2007 the population of BRM was estimated at 55 999, this accounts for 17, 1 % of the West Coast District population of 327 548 people. Between 2001 and 2006, the population increased from 48 076 to 54 658 at an average annual growth rate of 2.57%. However, it is projected that the growth will decline slightly between 2007 and 2015 to 2,3 %. The BRM has a large rural population, with 39,30 % of all households in 2001 located in rural areas. By 2007 this figure had decreased to 31% following the general trend of rural people migrating to urban centres in search of opportunity. 10 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The population of BRM is predominantly coloured (74%), while the white population comprised 19 % and the African population 6 % of the total in 2006, respectively. The population is fairly youthful with children aged 0-14 years and youths aged 15-34 years accounting for 27,8 % and 32,9 % of the total population respectively out of a total population of 55 999 (2007 figure). The youthful population demographic has long-term development implications for the municipality in that population growth will increasingly put pressure on facilities and resources of the BRM (Bergrivier Strategic Review, 2010) 1.4 THE ECONOMY The BRM is generally described as a low-growth area in the Western Cape. However the Western Cape Province has experienced real annual growth in excess of the national average over the last two decades. The subdued growth in the Bergrivier Municipal area is caused by: 3 Agriculture, the dominant sector, has been hampered by droughts, lower profitability and rationalisation of production techniques; 3 3 Fishing has also declined as a result of lower catches and tighter quota controls; 3 The N7 transport corridor from Cape Town to Namaqualand and further north is only peripheral to the municipal area, with Piketberg too close to Cape Town to function as a significant stop for passing trucks. (Bergrivier Spatial Development Framework [SDF], 2008). Being located to the northwest of Cape Town, the area does not fall within the in-migration corridor from the Eastern Cape; TABLE 1: THE DISTRIBUTION OF EMPLOYMENT IN THE BRM 11 SECTOR % CONTRIBUTION Agriculture, fishing, fo restry 55.8% Mining 1.6% Manufacturing 7.1% Electricity and water 0.2% Construction 3.6% Wholesale and retail 7.5% Transport and co mmunication 0.8% Finance and business service s 4.1% Communication ser vices 5.8% Government services 13.3% BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Factors such as the distance from Cape Town, low population densities, low levels of formal education, shortage of skilled labour, poor and expensive public transport and limited access to communication facilities are currently generic issues that are undermining economic development in the region. A concern is that the natural resources have limited capacity to support and service further development opportunities within the BRM. Eco-tourism is seen as a potential avenue for the generation of additional revenue in the BRM. Given the relatively small population of the area and the constraints in the two core economic sectors, tourism must be seen as the only significant driving force for growth of the Bergrivier towns. Activities within tourism would stimulate local investment, employment and economic growth but the seasonal, temporary or part-time nature of such jobs and activities distinctly suppresses the overall impact. 12 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 1.5 SOCIO-ECONOMIC INDICATORS Learners attending a class at a primary school in the BRM. Education is a major concern in the area. The Human Development Index (HDI) is a summary measurement of human development based on three dimensions namely life expectancy, education and income. The BRM has an HDI of 0,66, which is lower than that of neighbouring municipalities. The skills levels in the municipal area are cause for concern. In 2006, thirty percent (30%) of the population older than 14 years were illiterate. Existing skills initiatives in the municipal area should be intensified to create a suitability skilled workforce. In 2007 only 4% of the population had access to social grants, a figure that is the lowest in the municipal district. However, child support grants constituted 55 % of the total grants accessed in the municipal area. This phenomenon highlights the prevalence of teenage pregnancies in the municipal area. Only 26% of the social grants accessed were for old age pensioners. Drug-related crimes increased from 299 incidences in 2002/03 to 954 incidences in 2004/05. The increase in drug abuse is attributed to the substance “Tik”. Most teenagers are vulnerable to exposure to this drug. A study commissioned by the University of Cape Town on the prevalence of alcohol abuse and Fetal Alcohol Syndrome (FAS) in the municipal area found a high incidence of both (Bergrivier Strategic Review 2010). The BRM mission is to deliver cost effective, sustainable services with a well represented army of employees who are motivated to stimulate local economic development as well as environmentally sensitive development through transparent decision-making based on sound management principles within the ambit of unique character and cultural, historical heritage. 1.6 THE LOCAL AUTHORITY The BRM is divided into seven wards. Delivery of services is managed from the head office, which is situated in Piketberg. There are nine settlements within the BRM, of which three can be classified as major towns within the context of Bergrivier, namely Piketberg, Porterville and Velddrif. The March 2008 version of the Bergrivier Integrated Development Plan 2008/2009 provides for a capital budget of R 67,418,000.00 and an operating budget of R 159,190,489.00. The payment of rates and taxes contributes 17% and services (infrastructure) another 32.4% to the total income of the Municipality (Spatial Development Plan 2008). 13 Fish are salted and hung out to dry at Velddrif to make bokkems, a traditional South African dish. BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY ASSETS 2.1 BRM VISION AND MISSION FOR BIODIVERSITY Vision: To develop the Bergrivier Municipality in a sustainable manner through the integration of effective administration, biodiversity conservation and maintenance of environmental goods and services, development planning and growth of the local economy. Mission: To achieve the sustainable development of the Bergrivier Municipality through: (1.) effective conservation and environmental management of important biodiversity features; (2.) co-operative governance and collaboration with industry, civil society and communities; (3.) growth of the local economy; (4.) effective administration, land use and development planning and decision making. 2.2 DEFINITION OF BIODIVERSITY There is no universally accepted definition for biodiversity. Biodiversity in the BRM comprises the variety of ecosystems and includes the diversity of living organisms found in the different vegetation types, freshwater and marine ecosystems as well as the genetic variety between individuals and between different species 2.3 WHAT IS BIODIVERSITY? Biodiversity is a relatively new, technical term for nature (Maree & Vromans 2010). The definition above, however, refers to two aspects of the natural worldaroundus. Firstly it refers to its physical structure and properties (species, populations, communities) but also to the interactions that are continually taking place between these different components. These two parts are called biodiversity pattern and ecological process. In the case of the BRM biodiversity pattern is present as different vegetation types, as Sandstone Fynbos, Sand Fynbos, Strandveld or the different aquatic systems of wetlands, inland salt pans and estuaries (See Map 3 & 4). This pattern would include the populations of rare and endangered species that occur and that are specific to the municipal area. Ecological processes are those actions and interactions that enable the natural world around us to function in a healthy way. These processes may operate on a very small scale, including, for instance, bacteria binding nitrogen in 7 14 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 the soil or bees pollinating plants. They are also active on a much larger scale, as in the cases of a river in flood, the migration of fish along river systems or the movement of sand along a coastline. It doesn't take much thought to realise that these two parts of biodiversity are interdependent. A degraded river may cause a dramatic decline in water quantity, quality and species numbers and interrupt migratory patterns, or soil chemistry may change through agricultural use and alter nutrient cycling by micro fauna & flora. Lastly there are ecological drivers that maintain pattern and process: Examples include fires raging through thousands of hectares of fynbos, rainfall, temperature or very large herds of grazing wildebeest moving across the landscape. 2.4 DEFINITION OF ECOSYSTEMS An ecosystem is a complex of living organisms, their physical environment, and all their interrelationships in the area that they occupy. It includes the non-biological constituents such as minerals, climate, soil, water, sunlight, and all other nonliving elements together with the biological or living constituents. Ecosystems can therefore operate at the very small scale of, say, the saline pool on the top of a sandstone outcrop in the Sandveld to a whole wetland covering many hectares to a mountain catchments area covering thousands of hectares. The complexity of the natural systems around us has required simplification for use in practical planning. In South Africa scientists have chosen the planning unit of a vegetation type as a surrogate for biodiversity. 2.5 IMPORTANCE OF BIODIVERSITY AND ECOSYSTEMS The take home message is that the world has lost too much of its biodiversity already and that each of us has the responsibility to halt this trend. Approximately 60% of the Earth's ecosystem services have been degraded in the last 50 years with human impacts being at the cause of this degradation (Millenium Ecosystem Assessment 2005 in Sukhdev 2008). The loss of biodiversity is a threat to the functioning of the planet, our economies and human livelihoods. No world economy no matter how small or how large exists independently of the environment. According to Sukhdev (2008) there are two major learning challenges that we face today. Firstly we are still learning the “nature of value”, as we broaden our concept of “capital” to encompass human capital, social capital and natural capital. By recognising and seeking to grow or conserve these forms of capital we are slowly working our way towards sustainability. Secondly we are challenged by the juxtaposition in that we are struggling to determine the “value of nature”. Even though nature is omnipresent in our daily lives it is unrecognised by the markets, escapes pricing and defies evaluation. The degradation of our natural systems is driven by our inability to value ecosystems and biodiversity (Sukhdev 2008). The Economics of Ecosystems and Biodiversity interim report provides clarity on a number of key issues that underlie the challenges we are facing in achieving sustainability. The first realisation that poverty and the degradation of ecosystems and loss of biodiversity are inextricably intertwined. This primarily because the poor of the world live very close to the natural systems that they occupy and benefit directly from the services that they supply. If we are to be of service to the poor of the world we have to ensure that these communities live in an environment that is able to deliver these services to them. The second is an issue of ethics risks, uncertainty and discounting the future. We need to include an evaluation of risks such as the loss of ecosystem service and climate change in our decision making. We as humans are at the root of the problem it therefore follows that we have the ethical responsibility to be part of the solution by doing the right thing. We cannot extract benefit from the environment on a short term basis if the value of the commodity has a greater value in the future. 7 15 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Air quality Pollination Most plants and many crops are animalpollinated Green plants purify air, free oxygen Climate Ecosystems as carbon sinks prevent global warming Decomposing of toxic waste by organisms Food security All our food comes from biodiversity Pest control is 99% done by natural predators Environmental goods and services Water quality and purification by wetlands Disaster prevention by soil-binding plants 7 16 Soil quality Generated and maintained by microbes BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The wellbeing of every human population in the world is fundamentally and directly dependent on ecosystem services (Sukhdev 2008). More than a billion people world wide are directly dependent on fisheries, climate change could decrease the availability of water and fundamentally undermine water dependent economies and communities, human health will be impacted through the loss of biodiversity 50% of prescription drugs are sourced from naturally occurring plants that are threatened with extinction. Any farmyard in the Swartland or Sandveld may be wheat, barley, rye, maize, cattle, goats, sheep & horses. All of these agricultural products were obtained from the naturally occurring biodiversity of the grasslands of the world. Consider the freshwater fishing industry, the global annual catch is estimated at 14 million metric tonnes valued at $18.2 billion. The freshwater angling Because of our total dependence on biodiversity for industry is valued at 16 billion and if the service food, building materials, water, etc., it is absolutely industry that supports this form of utilisation is essential that biodiversity is integrated into land included the value jumps to $46 billion.

Many of these goods are in decline as a result of habitat transformation. One may ask oneself how important they have in the development of human civilisation and the pattern of occupation and land use within the municipal boundaries. It is highly recommended that the TEEB report for administrators is consulted when it is released in September 2010. The report aims to: 3 Showcase examples of how biodiversity has been incorporated in local policy and public management through valuation; 3 Give an overview of how assessments, including evaluation, can improve biodiversity related decision-making at a local scale, and 3 Provide an orientation for administrators on how to choose the right evaluation instruments to suit the local circumstances. It is, however, of greatest importance to keep in mind that, these ecosystem goods and services are delivered to people through populations of species going about their lives, interacting with each other and the physical environment they live in while adapting to ever changing circumstances. The term used to describe this is biodiversity. Biodiversity and ecosystem goods and services are inextricably linked. The loss of biodiversity means the loss of ecosystem goods and services and impacts negatively on human livelihoods. It is widely accepted that ecological systems (services) and the natural capital stocks (goods) that support them are critical for the functioning of the earth's life support systems. Global ecosystem services are estimated at $ 16-54 trillion (1012) per annum. The average is $ 33 trillion p/a as a minimum estimate. Consider that the global Gross National Product (GNP) is $ 18 trillion per annum. Natural environment's ecosystem services supply a service free of charge that is conservatively estimated to be close to double that of the global GNP. The destruction of those services will increasingly have to be borne by the economies of the world and locally by the Local Authorities of South Africa. In South Africa, the total value of ecosystems is conservatively estimated at R27 billion per annum. This estimate includes the production of biological resources as well as the final consumption of ecosystem services. The calculated value of biodiversity-dependent industries in the greater Cape region amounts to approximately R9,4 billion. In 2000 it was estimated that the pollinating services of bees to the fruit and honey industries amounted to R594 million, while in 2003, bird-watching tourism generated R16 million (Maree & Vromans 2010). In the case of the BRM it is possibly most relevant that nature based tourism for the Cape Floristic Region was valued at R 7.4 billion per year (Turpie et al., 2003). 7 17 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 2.6 THE ECOSYSTEM DIVERSITY OF THE BRM The municipality is situated in the Fynbos Biome which takes its name, unsurprisingly, from fynbos (derived from the Dutch 'fijn-bosch') the dominant vegetation of the region. Fynbos comprises three quite different vegetation types - fynbos, renosterveld and strandveld - all of which occur within the boundaries of the municipality. Fynbos is characterised by small-leafed evergreen shrubs that have an intimate relationship with fire. The BRM is topographically very variable and supports a mosaic of geological formations, altitudinal gradients, terrestrial habitats and important wetland and estuarine systems. South Africa is an exceptionally species-rich country: In fact, in terms of plants and animals it is the third richest in the world. In the Western Cape this is particularly true as this is the home of the Cape Floristic Region (CFR), the only floristic region in the world to occur wholly within the borders of a single country. The CFR is contained in the Northern arm of the Fynbos Biome. The Western Cape not only has 9 000 of the 18 000 flowering plant species found in South Africa, but of even greater importance is the fact that 70% of the species occurring in the Western Cape are unique to the region and occur nowhere else on the planet (Davis et al 1994). Half of the country's plant species occur in the CFR and 20 of the 21 critically endangered vegetation types are located in the CFR. The Bergrivier Municipal area therefore supports some of the most important biodiversity on the planet, and is one of the 34 globally identified biodiversity hotspots. The natural habitats were shaped over millions of years through climatic and geological events, species inhabiting the environment and more recently due to impacts associated with natural resource use by humans. 7 18 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 TABLE 2: PERCENTAGE OF A VEGETATION TYPE OCCURRING IN THE BRM Values of 100% indicate that the vegetation type occurs in the municipality only and nowhere else on earth.

This leads to a high number (more than 20) of endemic plant species on the mountain. Another botanical oddity is a small “lost” population of the small tree Pseudoscolopia polyantha, far away from its home range in the Eastern Cape and Southern KZN region (Maree & Vromans, 2010). According to Maree and Vromans (2010) the municipality is home to Piketberg Sandstone Fynbos, which occurs in this municipality and nowhere else in the world. In other words, it is endemic to the municipality. Piketberg Quartz Succulent Shrubland is a near endemic with more than 90% of the vegetation type within the municipality. See Table 2: The percentage of a vegetation type occurring in the BRM.

This vegetation is absent from rocky shorelines, and as it occurs on well-drained soils, it is not associated with wetlands. Plant community variation reflects the age of the substrate (often related to distance from the sea), natural disturbance regime (dune stability), distance from the high water mark, and the exposure of dune slopes (leeward versus seaward; Mucina & Rutherford 2006). Climate: Low rainfall, and often exposed to sea fogs and mist, which keep it significantly cooler than more inland vegetation types, even in midsummer. Highly saline in places, exposed to windblown sea spray, especially in winter, when onshore northwesterly winds predominate. Vegetation structure: Grasses dominate the vegetation type with low shrubs (<0.4m) high. There are no trees or large shrubs. Fairly high degree of succulence, as evidenced by species that span various vegetation types and which are not as succulent in other vegetation types (eg. Senecio littoreus; Cineraria geifolia), and a number of genera whose only succulent species occur in this coastal habitat (eg. Hebenstreitia, Dischisma). Annuals may be common. Many species adapted to being covered by mobile sands (eg. Psoralea repens), and thus able to root at nodes. Few geophyte species, but those that there are may be prominent (eg. Trachyandra divaricata). Key areas requiring conservation: Within the BRM this vegetation type is conserved in the Rocher Pan Nature Reserve. The habitat is well conserved and varies little across its distribution. The location of conservation areas to conserve Cape Seashore Vegetation is therefore not especially important. Management guidelines: As a pioneer plant community, Cape seashore vegetation is relatively resilient to disturbance. The habitat is sensitive to disturbance from off-road vehicles and occasionally trampling and construction, in particular the area around Dwarskersbos and Laaiplek. No vehicles should be allowed, and access by the public should be along raised boardwalks to minimise impacts. Fortunately this vegetation type can be easily rehabilitated. CAPE ESTUARINE SALTMARSH Position and features of the landscape: Within the municipality this vegetation community is only found at the Berg River Mouth. This permanent wetland is found on very shallow, silty alluvial terraces within the tidal zone and is defined by presence of seawater and high salinity. Climate: Characterised by low rainfall. The microclimate is cool due to adjacency to the sea with associated mist and fog. It is exposed to strong coastal winds throughout the year. 7 21 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Vegetation structure: A Cape estuarine salt marsh looks like a meadow and is dominated by herbs and grasses. All the vegetation is short and shrubby and most species are succulent (eg. Sarcocornia species) and Salicornia meyeriana, Triglochin spp., Plantago crassifolia). Relatively low botanical diversity when compared to other terrestrial systems. Special species: These estuarine salt marshes are particularly important to migratory waders that visit our shores during summer. Key areas requiring conservation: The Berg River Estuary is under severe pressure and urgently requires formal conservation status, as it is extremely important from an ecological perspective. Management guidelines: The Berg River Estuary is very vulnerable to industrialisation and urban development both within the estuary and along the shoreline. Estuarine salt marshes are characterised by very high levels of productivity, which explains their importance in providing food to migratory birds and as a spawning ground for inshore fish species. This area should be formally conserved due to its regional, national and international importance. CAPE INLAND SALT PANS Position and features of the landscape: These are natural depressions in the landscape that accumulate water. In sandy areas where they occur, their presence can usually be ascribed to an impenetrable clay or calcrete layer below the sand. These seasonal wetlands are extremely arid in summer. All are saline, some are extremely so, to the extent that they support vegetation along their verges only. Cape inland salt pans are common between Velddrif and Rocher Pan. Climate: Characterised by low rainfall. The microclimate is cool due to adjacency to the sea with associated mist and fog. Vegetation structure: There are no large trees, and small succulent shrubs and true succulents dominate (eg. Drosanthemum spp., Sarcocornia spp. and Salicornia meyeriana, Triglochin spp., Plantago crassifolia). There is a relatively low botanical diversity in this biologically harsh environment. Special species: Four “vygie” species are specialists of this habitat. Drosanthemum salicola is known from salt marshes from Nuwerus to Langebaan; Lampranthus salicola is known from this habitat in the Sandveld 7 22 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 and Saldanha regions, and Dorotheanthus clavatus and Erepsia brevipetala occur in the greater Hopefield district. All four species are poorly known, and probably threatened. Key areas requiring conservation: If one were to select areas especially in need of conservation, these would be the extensive salt marshes north of the Berg River and along the Sout River (tributary of the Berg River), with a number of rare and threatened plant species, as well as the Rocher Pan area. Many of the most important patches are small, and occur along the outer edges of seasonal wetlands. Management guidelines: These habitats have no agricultural potential and are often treated as waste ground. As a result, these areas are often used as dumpsites or as recreational areas, for off-road vehicles such as quad bikes. No vehicles should be allowed into these areas and stock should be fenced out. Alien invasive plants - in particular rooikrans (Acacia cyclops) and Port Jackson (Acacia saligna) are a problem in areas where these salt pans are less saline. The management of the underground water resource in the area is of paramount importance, as overuse of this resource will negatively impact this vegetation type. CAPE LOWLAND FRESHWATER WETLANDS Position and features of the landscape: Found in a variety of situations, from upland seepage areas and streams to lowland floodplains. These are seasonally inundated areas that are situated above the tidal zone. Climate: The climate is not a major determinant for this vegetation type, as it is typically associated with winter rains. Vegetation structure: Floodplains characterised by low grassland, with sedges dominant and occasional pools with floating aquatic plants. Taller shrubs may occur on slightly better drained soils. Dense patches of Typha and Phragmites reeds may occur where water channels get deeper, usually in areas of permanent water. In seepages and upland areas, an often dense shrubland (restios and Erica may be common), with reeds less common. Numerous alien invasive species are a feature, including Eucalyptus cladocalyx (red river gum), Acacia saligna (Port Jackson), Acacia longifolia, Sesbania punicea, Polygonum lapathifolium and Eichornia crassipes (water hyacinth). 7 23 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Special species: The lowland floodplains are not known to support many special plant species, but are of major importance for vertebrates such as frogs and birds. Key areas requiring conservation: Excellent examples of the silty floodplains are present from approximately 3km north of Velddrif to the Kersefontein area. Management guidelines: These habitats support palatable plants and areas that are often heavily grazed and trampled by cattle. Cattle and horses should be kept out of these areas in the rainy season between May and October. The availability of water makes them susceptible to invasion by alien plants. Any diversion of water away from a wetland or disturbance within the wetland, such as digging of dams or sump pits, should be avoided. HOPEFIELD SAND FYNBOS Position and features of the landscape: Occurs on flat plains with deep acid sands and no outcropping bedrock. Underlain by shale that is visible in places, notably along riverbanks. The very few rivers cutting through this landscape thus tend to support a thin band of Renosterveld type vegetation where shale is exposed as a result of erosion. It reaches its northernmost extent around Aurora, where the composition of Proteaceae, Geraniaceae and certain Asteraceae changes to reflect transition to more arid Leipoldtville Sand Fynbos. North of the Berg River it forms a mosaic with Flats Strandveld, which can be regarded as a diffuse and extensive ecotone (transition area) between the two main types. Climate: Climate is not a major driver of this vegetation type. Typical winter rainfall area, with hot, dry, windy summers, and a high incidence of fog in autumn and winter. Vegetation structure: Medium to tall fire-prone shrubland. Restios and ericoid shrubs of various families predominant, but Proteaceae may be co-dominant in places. Scattered thicket (strandveld) elements, notably Gymnosporia buxifolia and Euclea tomentosa. Annuals abundant, especially after fire. Geophytes may be common, but most species shared with other Sand Fynbos systems. Special species: Red Data listed Proteaceae in this area (north of the Berg River) includes Leucospermum rodolentum (widespread in west coast area), L. hypophyllocarpodendron spp. L. canaliculatum (Aurora to Milnerton), Leucadendron foedum (mainly Hopefield area), Serruria decipiens (Graafwater to Melkbos), and Serruria fucifolia (Gifberg to Hopefield). Other rare/threatened or endemic species include Aspalathus albens, A. ternata, Lachnaea capitata, Lachnaea grandiflora, Phylica harveyi, Phylica thunbergiana, Metalasia adunca, Nemesia strumosa, Lampranthus explanatus, Relhania rotundifolia (often in clay lenses), Oxalis suavis (common but very local endemic around Hopefield), and Lepidium flexuosum (poorly known). Metalasia capitata shared with neighbouring Sand Fynbos types. Key areas requiring conservation: This vegetation type is very poorly conserved, with large areas transformed by agriculture and invaded by aliens. However, large intact areas still remain and these should be the focus of conservation efforts, especially where these include ecotonal elements (such as clay lenses and Renosterveld contact zones, and upland elements such as those found near Aurora), and where they border existing public or private conservation areas. Management Guidelines: Major pressure sources are agriculture (potatoes, rooibos, wheat) and alien invasive plants (mainly Acacia saligna and A. cyclops). The removal of alien invaders should be regarded as a priority for this 7 24 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 vegetation type. The carrying capacity of this vegetation type is low, and the stocking of game reserves should be well controlled and closely monitored to prevent the degradation of this habitat. No further transformation of good quality examples of this vegetation type should be authorised, unless offset by significant conservation gains in accordance with the latest regional guidelines for biodiversity offsets (Department of Environmental Affairs and Development Planning 2007). These guidelines suggest that for every 1ha of intact habitat lost, at least 15ha of the same quality should be conserved. LEIPOLDTVILLE SAND FYNBOS Position and features of the landscape: This vegetation type is one that is heavily targeted by agriculture, in particular for strip cultivation of cereals, potato and, to a lesser extent, rooibos production. Leipoldtville Sand Fynbos occupies the well-drained sandy coastal plain Climate: Typical for the region, low rainfall with hot, dry summers, and mild winters. Most areas experience a limited number of days with morning coastal fog. Vegetation structure: Medium to tall shrubland, with prominent Restionaceae, Proteaceae, Fabaceae (Aspalathus), Polygalaceae (Nylandtia), relatively few succulents or deciduous species, and many annuals. Geophytes are fairly diverse, but not abundant. Special species: This vegetation type is exceptionally rich in special species, which is one of the primary reasons for concern about the high rate of habitat loss in the area. Species totally or largely restricted to this unit include Albuca clanwilliamigloria, Athanasia sertulifera, Cullumia floccosa, C. micracantha, Felicia josephinae, Heterorachis sp. nov., Steirodiscus capillaceus, Wahlenbergia constricta, Erica dregei, Pelargonium appendiculatum, P. attentuatum, P. fasciculaceum, Babiana confusa, Geissorhiza barkerae, G. louisabolusiae, Limonium sp. nov., Leucadendron brunioides var. flumenlupinum, Leucospermum arenarium, Lotononis racemiflora, Agathosma insignis, A. involucrata, Macrostylis hirta, Dischisma squarrosum, and Manulea pillansii. Additional rare and/or threatened species found within this unit inlude Caesia sp. nov., Babiana scabrifolia, Euchaetis tricarpellata, Leucadendron procerum, L. loranthifolium, Serruria fucifolia, S. decipiens, Leucospermum rodolentum, Lachnaea capitata, L. grandiflora, Eriospermum arenosum, Lebeckia leucoclada, Argyrolobium velutinum, Lotononis bolusii, and Phylica cuspidata. Aspalathus rostripetala is known only from one collection, possibly in this habitat, north of Citrusdal. Sandveld Lachenalia 7 25 Key areas requiring conservation: This unit is poorly known botanically, with both Cullumia micracantha and C. floccosa (fairly large perennial shrubs) not having been collected for over 100 years. The remaining areas of this vegetation type should be considered to be irreplaceable. Within the municipal boundary particularly important areas for conservation of endemic species are areas around Aurora, between Redelinghuys and the Engelsman se Baken area (Driefonteinberg and areas to south), the area ffrom Redelinghuys to Paleisheuwel (including Ratelrug). BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Management guidelines: Given the exceptional concentration of rare, A NEW INSECT ORDER: THE SANDVELD HEEL WALKER threatened, and localised species in this unit, the ongoing and rapid Small invertebrates have not been adequately sampled or much transformation of this habitat by researched in this part of the world. From the groups that are better agriculture is of major national known, such as the butterflies and dragonflies, it is evident that conservation concern, made worse many species are under threat and some species have already been by the fact that no formal lost. A new order of insects, Mantophasmatodea, was recently conservation areas protect this discovered in Southern Africa, and the Sandveld hosts one of the vegetation type. In this regard the 14 species of this group, the Sandveld heel walker (Karoophasma Greater Cederberg Biodiversity biedouwensis). This species shelters at the base of the restios that Corridor (GCBC) project is of critical grow prolifically on the sandy soils of the Sandveld. Their chosen importance, as it seeks to involve habitat make them very vulnerable to ploughing. private landowners in conserving key portions of natural habitat in this area. Agricultural transformation, primarily for potatoes and rooibos, is by far the most important pressure on this habitat, along with the associated effects such as a drop in the water table, which may result in the death of entire groundwater-dependent ecosystems. No further transformation of good quality examples of this vegetation type should be authorised unless offset by significant conservation gains, in accordance with the latest regional guidelines for biodiversity offsets (Department of Environmental Affairs and Development Planning 2007). These guidelines suggest that for every 1ha of intact habitat lost, at least 15ha of the same quality should be conserved. Overgrazing of certain areas is also a major problem, and alien invasive plants (primarily Acacia) are an issue in places, especially in wetlands. This is a fire-driven system, but an appropriate fire frequency is likely to be once every 15 to 25yrs, given the relatively dry climate and slow growth rates. SWARTLAND SILCRETE RENOSTERVELD Position and features of the landscape: This is a rare and unusual form of Renosterveld characterized by a stony substrate, usually dominated by silcretes (cement-like silica deposits sometimes mistaken for quartzite), but may also feature ferricretes (koffieklip). Usually occurs within Swartland Shale Renosterveld areas. Rocky nature means that it is often found on highpoints and breaks of slope (eg. upper convex slopes of river banks). Usually less densely vegetated than typical Shale Renosterveld, and thus often heavily eroded. Although it may appear degraded at first glance, this is its natural state. Climate: Hot, dry summers, and fairly high incidence of fog in winter and autumn. Vegetation structure: Usually a fairly sparse vegetation cover, with large bare areas of exposed silcrete or ferricrete. Low succulent shrubs dominate, with various bulbs and annuals. Floristically not very distinct from Shale Renosterveld, but structurally tends to be shorter and sparser, with a greater concentration of special species. Special species: In this region a number of Lampranthus species are regarded as being of conservation concern, including L. dilutus and L. filicaulis. Muraltia trinervia and M. origanoides are both of conservation concern. A number of rare bulb species may be present. Key areas requiring conservation: All remaining examples of this habitat should receive the highest conservation priority rating, due to its very limited extent, and large number of rare, localised, or undescribed species. Formal conservation of this habitat type is essential. 7 26 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Management guidelines: Due to the perception of this often sparsely vegetated rocky habitat as waste ground (“afvalgrond”) it is very vulnerable to transformation and damage. Existing pressures include quarrying for road gravel, road construction, dumping, and recreational use by off-road vehicles. The succulents and shallow soils are also extremely sensitive to trampling and crushing by stock, especially cattle. SWARTLAND SHALE RENOSTERVELD Position and Features of the Landscape: In the municipality this lowland habitat is present along the base of the Piketberg, in the northwestern Swartland, and in isolated patches where shales are present at the surface, often along riverbanks and at the base of hills. It is restricted to shale-derived clays, occasionally with outcropping shale, ferricrete, and even quartz pebbles. Soils may be well-drained to seasonally waterlogged. Heuweltjies (eroded, inactive termite mounds) are occasionally a feature. Climate: Typical winter rains and summer drought. Strong winds are not a factor driving vegetation structure. Some areas may get significant early morning mist and fog, especially in autumn and winter. Vegetation structure: Low, relatively open shrubland, with many deciduous elements and a high species diversity. Succulents and annuals may be common, and geophytes are a particular feature of this unit, especially after fire. Trees are usually rare, except along streams. Restios (mostly Calopsis viminea and Ischyrolepis capensis) may be present, but are never dominant. Often very grassy in the first few years after a fire (especially Ehrharta, Tribolium, and Pentaschistis spp.). This is usually a fire-driven vegetation type. Special species: This vegetation type is packed with rare and threatened species. Portions of this type found within the municipality are poorly known. Those that occur within the study area include a new species of Apatesia (vygie), a new species of Geissorhiza, a possible new species of Diosma (buchu), Athanasia adenantha, Erepsia ramosa, Hesperantha pallescens, and Lampranthus dilutus. The rare Babiana longiflora was only described in 2004 and is known mainly from this unit along the base of the Piketberg mountain, and the rare Babiana inclinata was only described in 2007. Key areas requiring conservation: All Renosterveld areas are conservation priorities, but particularly important are the slopes around the base of the Piketberg, which have produced a number of new species in the last few years. Special areas known to be important are the Weltevrede Kleigat area north of Engelsman se Baken (home to 2 new species), and some of the shales northwest of Aurora. Management guidelines: This is normally a fire-driven system, and should be burnt on a cycle of once every ten to twenty years, although some sparse, succulent dominated examples may be fire-resistant. The threat of alien invasive grasses (such as Lolium and Avena spp.) is particularly severe in the post-fire environment, and this can be minimised by locating stock feeding points (which contain alien grass seeds) at least 300m away from Renosterveld areas. NORTHERN INLAND SHALE BAND VEGETATION Position and features of the landscape: This vegetation type is not unique to the study area and extends far to the south, into the Ceres district. The shale band is a narrow feature (50 to 300m wide) running along the slopes of the Groot Winterhoek. As the shales are softer than the adjacent sandstones, they weather more quickly and evenly, 7 27 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 and thus often form low points (saddles) in the landscape, with a smoother, concave profile. Heuweltjies may be present. The soils range from well-drained to waterlogged in winter. Climate: Variable, but essentially hot and dry in summer and mild to cold in winter, occasionally with snow in upper elevations. Vegetation structure: Low to medium shrubland, getting shorter in arid areas and at higher altitudes. May include waboomveld (Protea nitida) and substantial grassy elements, especially after fire. Special species: Within the study area very few special species are known to be strictly associated with this vegetation type, as many shale band specials are widely distributed (e.g. Cederberg to Hex River Mountains), or concentrated in the mountains outside the municipality. Key areas requiring conservation: This largely montane vegetation type is well conserved within the Cederberg Wilderness Area and Groot Winterhoek Wilderness Area, and no specific areas requiring additional conservation have been identified. Management guidelines: This vegetation type has hardly been transformed, due mostly to its montane nature and occurrence within formal conservation areas. Small portions (<5%) have been impacted by roads, gravel quarrying, protea farming, and pine plantations. This is a fire driven system, and is burned regularly across most of its range. BERG RIVER FLATS STRANDVELD - SAND FYNBOS MOSAIC Synonyms: This is a new vegetation type, previously mapped as Hopefield Sand Fynbos by Mucina & Rutherford (2006). Position and features of the landscape: This is essentially an extremely diffuse mosaic ecotone between Saldanha Flats Strandveld (which is itself something of an ecotone) and Hopefield/Leipoldtville Sand Fynbos. The unit is found primarily north of the Berg River, extending up to the Aurora area, and then in a thin band almost to Elands Bay. It is very clear both on the satellite imagery and on the ground as a discrete unit, due to the patchy soil patterns that have produced a patchy agricultural pattern. Landowners have typically ploughed the Flats Strandveld areas and left the patches of purer Sand Fynbos, reflecting former agricultural trends of planting wheat. With a shift to rooibos and potato cultivation this may change, with the remaining Sand Fynbos areas coming under pressure. The landscape is a generally flat to gently rolling plain either side of the Berg River. A mosaic of loamy sands (Flats Strandveld) and acid sands (Sand Fynbos) have produced the observed vegetation patterns. Underlying clays are evident in places, especially where the sands are thin or absent, and seasonal pans have formed in the depressions. Some significant linear seasonal wetlands occur in the area, such as the Sout River, and due to the slightly saline clays in these areas they tend to support Salt Pan type vegetation. Climate: Hot, dry and windy summers, with a fairly high incidence of morning mist in the Berg River Valley. True sea fogs seldom penetrate this far inland. It can be expected that rainfall is slightly higher towards the mountainous area behind Aurora. Vegetation structure: Characterised by elements of both Flats Strandveld and Sand Fynbos, with a high percentage of restios, some succulents and patches of Proteaceae. As befits the mosaic nature of the vegetation type, the plant communities can be very patchy, with up to 50% community changeover in less than 100m. Due to the mapping 7 28 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 scale it was not possible to distinguish these as discrete units, and hence the choice of designating a mosaic vegetation type. Special species: Special species from both parent vegetation types occur in the area, including Leucospermum rodolentum, L. hypophyllocarpodendron ssp. canaliculatum, Leucadendron foedum, Serruria decipiens, Serruria fucifolia, Phylica thunbergiana, Metalasia adunca, and Metalasia capitata. Lepidium flexuosum, Passerina filiformis ssp. glutinosa, and Manulea augei are all poorly known species that may occur here. Babiana petiolata and B. confusa are regional endemics. Ursinia sp. nov. is a new species that is largely endemic to this unit (north of the Berg River), extending into pure Flats Strandveld in places. Freylinia visseri is a very rare species found only in this vegetation type north of the Berg River. Key areas requiring conservation: This vegetation type is extremely fragmented by agriculture, and it is suggested that conservation priorities be guided by the largest contiguous patches and known occurrences of Red Data Book listed species. It is also important to include as many seasonal pans and wetlands (including the Sout River) as possible, as these provide important habitat variation. Management Guidelines: Main pressures are agriculture (wheat, rooibos, and potatoes), and alien plant invasion. Establishment of further large centre pivot operations, and new rooibos fields should be restricted to existing lands, and should not be allowed in areas with known Red Data Book species. Rooibos cultivation should incorporate windrow strips of natural vegetation, as this provides windbreaks for the young plants, prevents erosion, and is a valuable source of natural plant material for rehabilitation, in addition to being a habitat for animals and plants. Control of alien invasive plants (mainly Acacia cyclops and A. saligna) is a priority in many areas. LANGEBAAN DUNE STRANDVELD Position and features of the landscape: Widely distributed, ranging from Bokbaai in the south to Rocher Pan and Dwarskersbos in the north. Surprisingly large areas on its inland fringes were ploughed many decades ago, often making the boundary between this and Saldanha Flats Strandveld difficult to pinpoint. Found on calcareous (alkaline) dune sands and poorly developed calcretes mixed with sand. Climate: Hot, dry, and windy summer conditions, with some areas cooled by regular overnight and early morning sea fogs, especially in autumn. Strong onshore winds in winter may stunt vegetation close to the shore, due to high salt levels. Vegetation structure: Usually a mixed shrubland of 0.5 to 2m tall, with Thicket elements especially common where there are shallow sands over calcretes. Fire not a major driver of dynamics total period of stability and substrate type are more important. Younger areas with much less Thicket component, and may be dominated by low shrubs and grasses. Relatively low succulent diversity, but these species may be common. Geophytes not a major feature, but spring annuals can be spectacular on the sandy soils. North of the Berg River this vegetation type becomes less speciesrich, with a notable drop in the number of special species. 7 29 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 GRANT'S GOLDEN MOLE (Eremitalpa granti) This is a small mammal, unrelated to true moles, with a total length of 7,0 to 8,5 cm and with a mass of 16 to 32 g. Because they live underground, they do not have eyes. Although the juveniles are born with eyes, a thick layer of skin soon covers the eyes and they become totally blind in adulthood. These animals are listed by the IUCN as an endangered species. They are found in very unproductive coastal dunes, and never move inland because the soils are too compacted. They are nocturnal and surface at night to prey on insects moving on the sand. During the day they rest and slow down their metabolism a daily hibernation. The average home range for this remarkable species is 4,3 ha quite a large area for such a small species. Special species: Species of conservation concern that may be found north of the Berg River include Caesia sp. nov., Limonium acuminatum, and Otholobium venustum. Babiana petiolata is a fairly common endemic of the northern parts of this unit and adjacent Lambert's Bay Strandveld. Key areas requiring conservation: Perhaps the best examples of this vegetation type north of the Berg River occur between Rocher Pan and Elands Bay, and part of this is within the Rocher Pan NR, and part of it within private conservation areas. The Dwarskersbos area supports some significant kersbos (Pterocelastrus tricuspidatus) thickets, threatened by development. Management guidelines:This habitat is well conserved within the West Coast National Park, and in various other smaller reserves. An effort should be made to keep the main ecological corridors intact, and to prevent fragmentation. This is not a fire driven system. Alien plant invasion (mainly Acacia cyclops) is relatively slow (compared to the south coast), due to the aridity of the area in summer, but urbanisation is a threat in places (Velddrif, Dwarskersbos). GRAAFWATER SANDSTONE FYNBOS Position and features of the landscape: Widespread and common within this area, wherever there are semi-arid sandstone habitats. Occurs west of the Cederberg and all the way to the coast near Elands Bay. Forms distinct inselbergs surrounded by Leipoldtville Sand Fynbos on the deeper sands. Typically at moderate to low elevation, and is replaced by Olifants, Piketberg and Cederberg Sandstone Fynbos in wetter positions. Typical formation is a heavily weathered sandstone cap, sandy slopes with scattered rocks, and small sandy plateaus. Small Afrotemperate forest patches often associated with sheltered positions in this unit, especially on south and southeast aspects, but these are usually small. Climate: Quite variable, but basically hot and dry in summer and mild in winter. The more coastal areas (such as Baboon Point) are exposed to extensive sea fogs, which undoubtedly supplement the available moisture. Vegetation structure: Typically a medium to tall shrubland, with extensive thicket elements in more fire protected areas. Deeper sands dominated by Restionaceae, often with prominent Proteaceae. Prominent displays of annuals, especially in burnt areas. Moderate diversity of bulbs. Succulents may be common, especially on rocky outcrops, where dwarf succulents and bulbs (in very shallow soils) may be a feature. Special species: This unit supports a large number of rare, threatened, or localised plant species, some of which are shared with Leipoldtville Sand Fynbos. Gladiolus comptonii is rare and restricted to the Heerenlogenment. Conophytum obcordellum spp. rolfii is endemic to the sandstone outcrops near Eland's Bay. Oscularia compressus is 7 30 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 found only near Redelinghuys. Babiana confusa, B. ecklonii, Otholobium venustum, Pelargonium appendiculatum, P. fasciculaceum, Aloe framesii, Cullumia micracantha, Wahlenbergia massonii, Lebeckia leucoclada, Lotononis racemiflora, Sparaxis roxburghii, Agathosma involucrata (Bergvlei only), A. sladeniana, Dischisma squarrosum, and Manulea psilostoma are all species of conservation concern, found or potentially found within this unit. Most of the Proteaceae listed under typical species are currently Red Data listed. Key areas requiring conservation: Large areas have undergone transformation in the last twenty years, primarily for rooibos tea cultivation, and this unit is now threatened, with many fragments having become ecologically isolated. All wetland areas within this unit are high priority conservation areas, as are all known point localities for special species. Management guidelines: This is a fire driven system, and as many fragments are now surrounded by - or very close - to agricultural lands, fires are strongly resisted by landowners. This means that in many areas the natural vegetation is becoming senescent, with species loss possible in the near future. Further fragmentation of this habitat should be avoided, especially where natural habitat borders on Leipoldtville Sand Fynbos and upland areas. Landowners should be encouraged to burn most areas once every 15-20 years. Alien invasive vegetation is now an issue in some areas (especially Acacia and pine), and all invasive species should be removed. Rooibos tea farming should ideally be conducted within the natural veld, on an organic basis, without wholesale ploughing. At the very least strips of natural vegetation (minimum of 15m wide) should be left between ploughed strips (to reduce soil erosion and wind damage to young rooibos, and to maintain ecological connectivity), and ideally rooibos should be interplanted in extant vegetation and hand harvested, without spraying of harmful chemicals. CEDERBERG SANDSTONE FYNBOS Position and leatures of the landscape: This vegetation type is dominated by rugged rocky outcrops with gullies and flats of deep sand. It occurs in a small northern section of the Groot-Winterhoek Mountains. The vegetation grows on acidic sands derived from the Table Mountain Sandstone group. Damp sands are dominated by restio, which gives way to shrubby growth as aridity increases. Climate: The rainfall varies between 180-600mm per annum, with hot dry summers and sometimes freezingly cold winters (3 to 30 days of frost per year). Vegetation structure: Predominantly asteraceous (daisylike), restioid and proteoid fynbos. The vegetation type is characterised by a high number of endemic species. Key areas requiring conservation: This vegetation type is well conserved in the statutory conservation area of the Cederberg Wilderness Area. Management guidelines: A small percentage of the vegetation type has been transformed to agricultural production, primarily rooibos and vineyards. Most of the extent is mountainous. Pinus radiata, an alien invasive species, is of particular concern and should be eradicated. This is a fire-driven system that should burn regularly. OLIFANTS SANDSTONE FYNBOS Position and features of the landscape: This vegetation type is located on the lower slopes of the Voorberg Mountain from Saron northwards to the Olifants River Mountains. The altitude where this vegetation occurs 7 31 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 varies between 200 and 1200m on gentle to steep slopes as well as along the broad valley bottoms. The acidic soils are derived from Table Mountain Sandstone. Climate: The area receives between 250 and 700mm rain per annum, peaking in May and August. The summers are hot and dry and winters mild with a frost incidence of 3 to 10 days per annum. SPECKLED PADLOPER (Homopus signatus) Photo google.com. Very little is known about the smallest tortoise in the world, which can only be found in the Piketberg, Klawer and Calvinia areas - nowhere else in the world!. Adults are between 60-80mm in length with a weight of 70g for males and 140g for females. They are active in the early morning, when they feed on small succulent plants growing between large rocks., and are most active during the spring and autumn, when they breed. The tortoises consent to mate with a nod of their heads, and the females lay a few eggs in moist areas beneath rocks. After 100-120 days young emerge that are no more than 30mm long and weigh just 7g. This tortoise is currently threatened by habitat destruction through overgrazing, mining activities and collection for illegal pet trade. Vegetation structure: The vegetation type is characterised by a combination of vegetation communities that tend to occur on rocky west-facing slopes of the Cederberg. The rock provides fire protection and is dominated by asteraceous fynbos and Cape Thicket interspersed with low trees and tall shrubs. Proteoid fynbos is most prominent on the lower slopes and sandy plateaus, while the deeper sands and shallower soils support restioid fynbos. Key areas requiring conservation: This vegetation type is well conserved in the Cederberg Wilderness Area, with an additional 44% conserved privately. Management guidelines: Threatened by Pinus radiata: Its eradication should be prioritised. PIKETBERG SANDSTONE FYNBOS Position and features of the landscape: This vegetation type occurs mainly on the Piketberg Mountains in a triangle from the town of Aurora to Het Kruis, and on to the town of Piketberg. The vegetation type occurs from 100 to 1458m on Piketberg's Sebrakop. The landscape is characterised by steep slopes with small plateaus and peaks. The soils are acidic and derived from Table Mountain Sandstone. Climate: The area receives 320-860mm per annum with hot 7 32 dry summers and mild winters, 2-4 days of frost per year. Vegetation structure: The vegetation consists of restio dominated moister sands that become more shrubby as aridity increases. Proteoid and asteraceous fynbos dominate in the rocky areas. Cape Thicket is prominent as well. Key areas requiring conservation: This vegetation type has no formal conservation areas protecting it. While it is the most transformed BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 mountain fynbos vegetation type in the biome, it is regarded as a Least Threatened vegetation type. Areas on deeper sands, particularly those on the top of Piketberg, have been transformed to agricultural land, primarily for fruit production. Management guidelines: Acacia saligna, an alien invasive plant, is scattered over wide areas and should be prioritised for eradication. WINTERHOEK FYNBOS SANDSTONE Position and features of the landscape: This vegetation type occurs from the Dasklip Pass in the north to Saronsberg. The landscape is a moderately undulating high plain in the west with rugged peaks in the south and south east of the Groot Winterhoek. The soils are acidic and derived from Table Mountain Sandstone. Climate: This vegetation type receives between 370-1350mm per annum. The south easterly winds occasionally bring heavy mist precipitation in summer. Summers are warm to hot and winters can be bitterly cold with 10-30 frost days per annum. Vegetation structure: The vegetation consists of restio dominated moister sands that become more shrubby as aridity increases. Proteoid and ericaceous fynbos are found at higher altitudes which grades into an asteraceous fynbos at lower altitudes. Cape Thicket is prominent on the lower slopes. Special species: Numerous endemic taxa, including several species each of Aspalathus and Phylica, as well as some Proteaceae, succulents and the orchid Disa introrsa such as the rare Ixianthes retzioides, which is limited to mountain stream banks in the area, are found here. (Mucina & Rutherford 2006). Key areas requiring conservation: This vegetation type is well conserved in the Groot-Winterhoek Nature Reserve and wilderness area. It is regarded as least threatened. Management guidelines: Pinus radiata, an alien invasive plant is a threat and should be prioritised for eradication. This is a fire driven vegetation community that should burn at regular intervals. The Groot Winterhoek Wilderness, with its extraordinary rock formations and popular hiking routes, lies about 120 km north of Cape Town. It is situated in the Groot-Winterhoek mountain range east of Porterville. The Groot Winterhoek conservation area comprises 30 608 ha, of which 19 200 ha was declared a wilderness area in 1985 and the remaining 11 408 ha is managed as a nature reserve. As the name Groot Winterhoek suggests, winters are cold and wet, while summers are moderate. The average annual rainfall is 1 450 mm, with the heaviest rains between April and September. Winter nights are very cold with temperatures well below freezing, characterized by heavy frosts and frequent snowfalls. The landscape is rugged and mountainous, with altitudes varying between 1000 and 2077 m above sea level. For the most part the rock formations are Table Mountain Sandstone. This geological formation weathers readily into an acidic sandy soil substrate that is easily eroded. 7 33 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Groot-Winterhoek is also one of the eight protected areas that constitute the Cape Floral Kingdom World Heritage Sites. In total these heritage sites cover some 553 000 ha. World Heritage Sites are proclaimed to recognise and protect areas of outstanding natural, historical and cultural value (http://whc.unesco.org/en/list/1007). PIKETBERG QUARTZ SUCCULENT SHRUBLAND Position and Features of the Landscape: The largest patch of this vegetation type occurs on the farm Draaihoek between Piketberg and Eendekuil, also in the vicinity of Het Kruis and Redelinghuys and at Sauer on the South Western foot of the Piketberg. It occurs at altitudes that vary between 120-160m. The vegetation is unique to the Porterville formation. The weathering of the softer shale soils left behind hard quartz that forms an almost continuous rubble layer. Climate: This vegetation type receives little rain as it is in a rain shadow of the Piketberg Mountain. The climate is mild with only 4 frost days per annum, but summers are hot and dry. Vegetation structure: This is a unique vegetation type linked to the vegetation of the Knersvlakte. It is a low shrubland dominated by sturdy succulent Sarcocornia sp. accompanied by leaf succulents, such as contracted “vygies”, especially in the shallow trenches and depressions. The elevated sites with deeper soils support denser shrubland. Special species: Numerous endemic taxa refer to Mucina & Rutherford 2006. Key areas requiring conservation: There is no formal conservation of this vegetation type as it occurs entirely on private land Draaihoek in particular is very important for the conservation of this vegetation type. 2.8 TERRESTRIAL BIODIVERSITY: VERTEBRATES A third of South Africa's 280 mammal species have been recorded in the Fynbos region with a very low level of endemism. Some of the larger species such as the African elephant, black rhino, Cape lion and Cape buffalo were rapidly eliminated after the European settlers arrived in the area. The endemic blue antelope was extinct by the 1800's. Today only smaller antelope species such as the common duiker (Sylvicapra grimmia), Cape grysbok (Raphicerus melanotis), steenbok (Raphicerus campestris) and klipspringer (Oreotragus oreotragus) are found outside protected areas. Medium-sized mammals include species like the chacma baboon (Papio ursinus), porcupine (Hystrix africaeaustralis),honey badger (ratel) (Mellivora capensis), Cape clawless otter (Aonyx capensis), small spotted genet and yellow,small and large grey mongoose. (See Box: Cape clawless otter). Smaller species such as shrews, elephant shrews, moles, dormice, mice, rats and gerbils are well represented in fynbos. These species play an important role in fynbos regeneration either as pollinators or by dispersing seeds to favourable germination sites. The Cape mountain leopard is the top predator in fynbos (see Box: The Cape mountain leopard). There is not an unusual diversity of birds in fynbos, and although 250 species were recorded in the region, most of them are not specifically associated with fynbos. The uniform structure of fynbos offers fewer niches for foraging, breeding, and other activities and the low productivity and scarcity of food is the reason for the lack of diversity. Fynbos is however of interest to the avid bird enthusiast, and all six fynbos endemic birds are found within the BRM. These are the protea canary (Serinus leucopterus), Cape siskin (Pseudochloroptila totta), Victorin's warbler (Cryptillas victorini), Cape rockjumper (Chaetops frenatus) and the nectar feeding orange-breasted sunbird (Anthobaphes violacea) and Cape sugarbird (Promerops cafer) (Cowling and Richardson 2005). 34 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 THE CAPE MOUNTAIN LEOPARD (Panthera pardus) The Cape mountain leopard is the largest predator in the Western Cape, and is therefore the apex predator in our local ecosystems. The protection of apex species such as the leopard will ensure that other species are protected as well. This should ensure that food chains and ecosystems are kept functional. Leopard populations and numbers have decreased over time due to habitat fragmentation and degradation as well as to the persecution of leopards to protect domestic stock. Often these leopards are removed without the necessary gathering of information about the population and genetic status of the leopard and the reasons contributing to the conflict. As a result of this the Cape Leopard Trust was established. It aims to optimally facilitate conservation of the Cape's predator diversity through simultaneously implementing conservation strategies, research projects and tourism initiatives. Copyright: Cape Leopard Trust TABLE 3 THE KNOWN AND PRESUMED HISTORICAL INCIDENCE OF THE LARGER MAMMALS OF THE SANDVELD R E G I O N (COETZEE 2007) 7 35 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 POLLINATION IN FYNBOS Mammals, birds and insect species play a major pollination role in fynbos. There is an intense rivalry between plants species for the attention of pollinators, whose numbers are often too low to pollinate all the available blooms. This is particularly true of the geophytes, which flower just after fire when pollinators are scarce. Some plants, such as many proteas, are “generalists” that are pollinated by both birds and insects, while other are more specialised and need a specific species at a specific time to be pollinated. About 430 fynbos plant species are pollinated by birds: Some 100 of these species belong to the Erica genus and 79 to the family Proteaceae. A Cape sugarbird will visit 300 protea flowerheads per day during autumn and winter to satisfy its energy requirements About 80% of the 528 Erica species are pollinated by insects, bees, flies and thrips. One of the most recognisable orchid species in the Western Cape is the red disa (Disa uniflora) which emblazons the Provincial rugby team jersey. This orchid is common in the Groot Winterhoek, and is pollinated by a equally beautiful species of butterfly, the Mountain pride butterfly (Aeropetes tulbaghia). Disa uniflora THE BIG HERDS HAVE DISAPPEARED The Cape mountain zebra (Equus zebra zebra) is the smallest of the extant zebras, and the most restricted geographically. Its broad black stripes are closely spaced on a pure white body. Overall it is stockier than the Hartmann's zebra, has longer ears, and has a larger dewlap. The Cape mountain zebra formerly inhabited all the mountain ranges of the Southern Cape Province of South Africa. By 1922, however, only 400 were believed to survive. Today landowners are contributing to the conservation of the mountain zebra by setting favourable habitat aside for reintroduction programmes.

At a more local scale, climate modelling recently undertaken for the West Coast predicts increased temperature and decreased rainfall for the BRM (Archer et al 2008). South Africa is a water-scarce country, and our aquatic ecosystems are under severe pressure as a result of many competing demands on our limited water resources. All indications are that South Africa will reach its limit of potentially accessible water supplies between 2020 and 2030. For this reason, it is crucial that efficient water-use is encouraged (Maree & Vromans, 2010). The potato production area in the municipal boundary is solely dependent on underground water and aquifer recharge from rainfall for its continued viability, water supply is a key resource issue that requires management if the wetlands and water dependent ecosystems are to remain persistent on the West Coast (Ranger et al 2006). As with terrestrial ecosystems, aquatic ecosystems are comprised of all the living organisms and non-living elements in the surrounding water system (Maree & Vromans, 2010). These ecosystems have been further classified into eight sub-types of Wetland Ecosystems and River Ecosystems, based on their position and function in the landscape, and then further differentiated into 98 aquatic ecosystem types (Maree and Vromans, 2010). Aquatic ecosystems are interconnected: The impacts at the top end of a river in the mountain catchment may be felt all along the system to its point of entry into the sea. The aquatic ecosystems of the BRM have been severely impacted, as can be seen from Map 5: Former Extent of Aquatic Ecosystems in the BRM, and Map 6: Current Extent of Aquatic Ecosystems in the BRM. The current extent illustrated in the map may be interpreted as those river, tributaries and wetlands that can be considered to be ecologically functional at this point in time. The loss of functionality in the aquatic systems due to human induced impacts being the difference between the two maps. Most of the rivers have been heavily impacted. MAPS 5 AND 6: FORMER (LEFT) AND CURRENT EXTENT OF AQUATIC SYSTEMS IN THE BRM 7 37 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 MAP 7: CATCHMENTS AND RIVERS OF THE BRM MAP 8: CRITICAL BIODIVERSITY AREAS AND SUBCATCHMENTS WITHIN BRM (JOB ET AL) 2009 7 38 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 2.9.1 CATCHMENTS AND RIVERS If the water supply of a given region is to be managed in a sound and sustainable way, the entire catchment or catchments within a municipality will require management and should be identified as a single planning unit. Very importantly, catchment management will require formalised agreements or organisational structures between municipalities as the catchments, more often than not, extend beyond the boundaries of the municipal area. The BRM falls within the Berg River, Papkuils, Verlorenvlei and Olifants catchments, which is the management area administered by the Department of Water Affairs (DWA). In the department these areas are commonly referred to as Water Management Areas (WMA). It is important to understand the WMA as the departments activities related to monitoring, water licensing and allocation of staff and resources is based on this demarcation. Central to each of the WMA's is a major river system - in this instance the Berg River and the upper reaches of the Verlorenvlei. A striking characteristic of the catchment is the low density of drainage channels in the western parts of the catchment underlain by unconsolidated sandy recent deposits (Clark & Ractcliffe 2007). The Berg River Catchment covers an area of almost 9000 km2 in the Western Cape Province, and is subdivided 2 2 into 12 quarternary catchments ranging in size from 125 km near the headwaters to 2000 km in the drier western parts of the catchment (Figure 3.2). The river runs northward for 285 km, and drains into St. Helena Bay on the west coast of South Africa. Much of the catchment is relatively flat, except in the uppermost reaches (Clark & Ractcliffe 2007). As stated above, most of these rivers have been severely impacted through heavy use along the length of the river and through the regulation of stream flow to improve water security. The biodiversity of these rivers has been impacted through the modification of river banks, spread of alien invasive plants and animals, pollution from effluent and other waste, development, overgrazing and physical disturbance from livestock, vehicles and people. As a general rule of thumb the further on travels away from the main stem of the river and the steeper the gradient of the river the better the condition of the river. It is no small coincidence that the functional rivers in Map 6 above are closely linked to the mountain chains present in the municipality. The overall health of a river system is highly dependent of the quality of the vegetation growing along the riverbanks. The better the condition of the adjacent vegetation, the better the condition of the river. A broad band of riverine vegetation buffers the river against the impacts of adjacent land use. Furthermore, the roots of natural vegetation growing on the riverbanks bind the soil and prevent undercutting. The vegetation of these rivers often act to spilt the flow of water into a number of different smaller channels, which helps to reduce the impacts of flooding. This, in turn, provides more time for water to seep into the sediments along the course of the river, rehydrating the soils and feeding the aquifers. For this reason it is critical that any new land use, development or activity should be separated from the river by a buffer area (Maree and Vromans, 2010). Areas critical to biodiversity should be buffered by a minimum of 100m, Critical Ecological Support Areas should be buffered by a minimum of 50m and all other rivers should be buffered by 32m on either side of the river (Maree and Vromans, 2010), measured as a linear distance perpendicular to the river, away from the river and from the highest point of the bank. This is a guideline only, and specialist input should be sought at all times where these decisions are made. 7 39 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The Cape clawless otter (Aonyx capensis) is clawless, as the name suggests. They are reasonably common in marshes, rivers, streams and estuaries but because of their secretive behaviour they are seldom seen.When they play, they chase one another and indulge in mock fights, they also play animatedly with sticks and stones. They are mostly active during the day and, although they are fond of water, they spend more time out of it wandering in search of new feeding grounds. They have a taste for crabs and frogs, and less commonly eat fish. The otter's den is known as a 'holt'. Two to five young are born: They mature quickly and are soon schooled in the art of swimming and diving by their parents.

This is because the area experiences extended periods of inundation by water. Species of animals and plants that live in these areas have to be able to tolerate these wet, waterlogged conditions. A more detailed definition is supplied by the National Water Act (36 of 1998) as “land where the water table is usually at or near the surface, or land which is periodically covered with shallow water, and land that in normal circumstances supports or would support vegetation typically adapted to life in saturated soil”. The wetlands of the West Coast have been classified as isolated or non-isolated depending on connection or proximity to a riverine system, and further classified into floodplain wetlands, valley bottom wetlands, seep wetlands and depression wetlands. Within the Bergrivier Municipality the most numerous type of wetland by far are seeps, followed by depressions and valley bottom wetlands. However, the largest in terms of area are the valley bottom wetlands and floodplain wetlands. See Table 4: Summary of the inland wetlands and estuaries occurring within the BRM (as adopted from Job et al., 2008) and Map 10 above. Wetlands form stepping-stones for many taxa, including birds, reptiles, invertebrates and amphibians, as they move about the landscape. The functioning of these wetlands as stepping-stones is dependent on the permeability of the surrounding landscape matrix, which generally decreases as the landscape becomes degraded.

If an area supports several wetlands that together are greater than 500 ha in extent and no more than 1.5 km apart; and if more than 80% of the land cover is natural vegetation; then this should be recognized as a significant cluster to be prioritized for protection and proper management (Maree and Vromans, 2010). The following descriptions of wetland types is a summary based on the information contained in Job et al 2009. The wetland types found within the BRM are: FLOODPLAIN WETLANDS ALLUVIAL FLOODPLAIN Alluvial floodplains occur throughout the BRM the largest being the Berg River and its tributaries. Other alluvial floodplain wetlands can be found along the Verlorenvlei, Kruismans, Krom Antonies and Hol Rivers and the Papkuils that feeds into Rocher Pan. The climate where these systems are found is variable with a steep rainfall gradient from west to east across the municipality. The rivers are both permanent and non-permanent systems. Alluvial floodplains are characterised by: 3 3 wide river valleys; 3 sandstone and shale bedrock outcroppings within river channels; 3 braided meandering river channels. occurrence on acid sands of varying depth; Generally, alluvial floodplains have a band of perennial trees (often alien) and tall shrubs on the river bank, with swathes of varying width of reeds, sedges and palmiet extending on either side of the riparian tree band. Major threats and impacts: All of the alluvial floodplains in the planning domain are highly threatened by water abstraction both surface (the many dams on the Berg) and groundwater, especially for potato farming. This is threatening the seasonal inundation of the floodplain, and so the persistence of floodplain vegetation and wetlands. There is also extensive invasion by alien vegetation, with roads and railways, irrigation canals, urban and rural development comprising lesser threats. 7 42 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 SANDVELD FLOODPLAIN Sandveld floodplain wetlands occur along the following river systems: 3 3 3 Verlorenvlei; Sout River (tributary to the south of the Berg River); Rocher Pan system. The climate in these areas is low rainfall (MAP less than 300mm), which occurs in winter. With the exception of Verlorenvlei, all of these rivers are seasonal in nature. Sandveld floodplains are characterised by: 3 occurrence on alkaline to neutral silts and sands of varying depth; 3 presence of subsurface calcretes and clays (water tends to be more permanent in these areas); 3 saline systems that have a high dependence on groundwater; 3 3 much of the flow being subsurface; wide, sandy systems with braided channels within an even wider floodplain. The wetland type occurring on sandveld floodplains is classified as Cape Inland Salt Pans / Marsh described above. Major threats and impacts: Like the other floodplain types, sandveld floodplains are threatened by infilling, in order to reclaim land for agriculture, development and roads. Salt mining is a major threat, due to the natural salinity of these systems. Water abstraction especially groundwater is predominant in these catchments, and could lead to the drying out of these floodplain wetlands. In particular the presence of boreholes within the floodplains themselves. SANDSTONE FYNBOS VALLEY BOTTOM Sandstone fynbos valley bottom wetlands permanent or seasonal wetlands that are scattered throughout the planning domain. They are located in the lowlands and the more mountainous areas, wherever sandstone fynbos vegetation types are found. Sandstone Fynbos Valley Bottom Wetlands can be characterised by: 7 3 being fed by hillslope seeps situated on higherlying ground; 3 comprised of a generally well-defined channel with riparian wetland of varying width; 3 fed by water seeping from the surrounding mountain slopes or springs; 3 being associated with upper and lower foothill river systems; 3 floating aquatics can occur in more permanent pools; 3 occurrence on acid sands. 43 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The dominant vegetation is a mix of low to medium height herbaceous species reeds, restios, grasses, sedges and scrub-shrub type vegetation small trees and proteoid and ericoid fynbos species. The vegetation type is Cape Lowland Freshwater Wetland described above. Major threats and impacts: The clearing of land for cultivation of potatoes and rooibos in sandstone fynbos has led to the loss or reduction the extent of sandstone fynbos valley bottom wetlands. Associated with rooibos cultivation, and other crops, is the use of chemicals and fertilizers which tend to alter the water chemistry in wetlands these acid systems are particularly vulnerable to a change in pH. These wetlands are threatened by fragmentation, as a result of roads crossing wetlands, rural development and draining of wetlands. All of these activities can lead to erosion within seeps. Sandstone fynbos is fire-driven vegetation and so alterations to the fire regime would lead to loss of species diversity. SEEP WETLANDS Both hillslope and basin seeps were scattered throughout the planning domain, the seeps have been grouped primarily according to the vegetation type in which they are found. These seeps are important areas for water supply, located as they are towards the source of rivers and streams, and for groundwater recharge SANDSTONE FYNBOS SEEP Sandstone fynbos seeps are characterised by: 3 3 occurrence in mountainous areas such as the Groot Winterhoek and Piketberg; being both permanent and non-permanent; 3 being drier in summer (although soils can remain wet) and inundated in winter; 3 occurrence on sandstone-derived acid sands. The seeps are fairly densely vegetated, and tend to be dominated by restioid (where sands are deeper) and proteoid fynbos and indigenous grasses, but can be invaded by reeds, such as Phragmites australis, and bulrush, Typha capensis, where disturbed or where water is more permanent. The vegetation type surrounding these seeps are all sandstone fynbos types, primarily Groot Winterhoek Sandstone Fynbos and Piketberg Sandstone Fynbos. Major threats and impacts: The last two decades or so have seen substantial clearing of dry and wet areas in sandstone fynbos for the cultivation of rooibos. These fields are often placed in wetter, seep areas. This leads to the almost total loss of wetland vegetation in and around these seeps, and so a radical deterioration in the quality of wetland habitat. Associated with rooibos cultivation, and other crops, is the use of chemicals and fertilizers which tend to alter the water chemistry in wetlands these acid seeps are particularly vulnerable to a change in pH. Hillslope and basin seeps are threatened by fragmentation, as a result of roads crossing wetlands, rural development and draining of wetlands. All of these activities can lead to erosion within seeps. Sandstone fynbos is fire-driven vegetation and so alterations to the fire regime would lead to loss of species diversity. 7 44 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 SAND FYNBOS SEEP 3 Sand Fynbos Basin Seeps are characterised by: occurrence on fairly low-lying, flat ground, predominantly around the southern Sout River (tributary of the Bergrivier) and inland of the Rocher Pan 3 3 3 system; occurrence in the vegetation type classified as Hopefield Sand Fynbos; occurrence on acid sands at altitudes lower than 150m. SAND FYNBOS HILLSLOPE SEEPS 3 The hillslope seeps are located on slightly higher ground, also in the upper catchments of the Verlorenvlei rivers in Leipoldtville Sand Fynbos; 3 occurrence on acid sands at altitudes lower than 150m. The seeps essentially occupy coastal sand flats. In Leipoldtville Sand Fynbos and Hopefield Sand Fynbos the vegetation is characterised by patches of medium to tall shrubs, which are separated by fairly dense restiolands. The seeps are generally vegetated, dominated by restios and the rush, Juncus kraussii, but may be invaded by reeds, such as Phragmites australis, and the bulrush, Typha capensis, where disturbed. Sarcocornia natalensis, which required seasonal freshwater flooding, can occur in sand fynbos seeps. Major threats and impacts: Same as for sandstone fynbos seeps. Potato and rooibos farming in the north, and wheat in the south, are having a significant impact on both wet and dry habitats in the sand fynbos vegetation types. Wetlands, in particular seeps, are being drained and filled in to provide fields for cultivation. This represents large-scale loss of wetland habitat. Where non-isolated seeps are destroyed, the consequences for the downstream catchments will be severe, leading to a loss of surface water in an area where irrigation resources are poor. Groundwater abstraction is having a serious impact on seeps. RENOSTERVELD HILLSLOPE SEEP These seeps are all non-isolated, and mostly located in the southern half of the domain, around the middle Berg River, the Boesmans River (major tributary of the Berg River) and the upper reaches of tributaries of Verlorenvlei. Renosterveld Hillslope Seeps are characterised by: 3 3 3 occurrence in groundwater discharge areas; location on clays meaning they are probably perched wetlands; occurrence at fairly low altitudes, on gentle slopes. Most of them lie in the south of the domain in Swartland Shale Renosterveld. These seeps are dominated by sedges and grasses, but are often impacted and so are invaded by kikuyu grass, Typha capensis and Phragmites australis. Major threats and impacts: The Swartland Shale Renosterveld has been severely transformed 90% has been totally transformed and remaining 10% lies in fragments across the landscape. The wetlands lying within this vegetation type have similarly been affected, largely by cultivation and livestock grazing. Many of these renosterveld hillslope seeps lie on the lowlands, which are ideal for agriculture, and so these habitats are highly threatened. 7 45 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 STRANDVELD SEEP Strandveld basin seeps are all coastal systems. They occur on the coast just north of Rocher Pan. These seeps are situated in Langebaan Dune Strandveld, and are essentially dune slack wetlands dominated by Juncus kraussi. They are seasonal wetlands that are fed by annual rainfall. These are usually saline systems and in the BRM occur on deep, neutral to alkaline sands. None appear to be important from a groundwater recharge perspective and are not situated in groundwater discharge areas either. These seeps are characterised by: 3 3 3 seasonal wetlands dependent on rainfall; occurrence in the lowlands in areas with low rainfall (250-350mm); saline systems on neutral to alkaline sands. Major threats and impacts: These seeps are severely impacted by agriculture. Many have been ploughed up and/or drained and/or are heavily impacted by stock grazing in them. As a coastal system these wetlands are threatened by coastal urban development. Additionally roads and rail lines running parallel with the coast split and fragment these seep areas. Alien trees, in particular Acacia saligna and A. Cyclops, are a significant threat DEPRESSIONAL WETLANDS SANDSTONE FYNBOS DEPRESSION A mix of isolated and non-isolated sandstone fynbos depressions occur in the Boesmans River (tributary of the Berg River) catchment. When vegetated they tend to be dominated by restioid and proteoid fynbos. The vegetation type surrounding the majority of these depressions is Piketberg Sandstone Fynbos, and the remainders are within Graafwater, Olifants and Cederberg Sandstone Fynbos. 3 3 3 3 3 Sandstone Fynbos Depressions are characterised by: being seasonal, shallow systems and dependent on annual rainfall; occurrence at altitudes above 200m in gently sloping terrain; occurrence on acids sands, situated in groundwater recharge areas. Major threats and impacts: The sandstone fynbos depressions are mostly impacted by the cultivation of crops mostly wheat in the Piketberg area. These seasonal systems are vulnerable to changes in hydrology such as the result of ground- or surface water abstraction. They are vulnerable to invasion by reeds, such as Phragmites australis, and bulrush, Typha capensis, where disturbed or where water is more permanent SAND FYNBOS DEPRESSION Many of the sand fynbos depressions lie on either side of the lower Berg River and are surrounded by Flats Strandveld Mosaic and Hopefield Sand Fynbos.The remaining sand fynbos depressions lie inland, in the Verlorenvlei rivers surrounded by Leipoldtville Sand Fynbos. Sand Fynbos Depressions are characterised by: 3 3 7 46 occurrence on deep acid sands with a silt or mud substratum; dependence on the availability of underground water; BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 3 3 being mostly isolated systems that are seasonally inundated; usually being unvegetated, but in instances where vegetation does occur it is dominated by restios and the rush Juncus kraussi. Major threats and impacts: Sand fynbos depressions are highly threatened by agricultural cultivation of crops such as wheat. Livestock graze and trample the depressions. These wetlands are also frequently fragmented by road and rail networks. RENOSTERVELD DEPRESSION Most of these depressions lie in the Swartland Shale Renosterveld. They are characterised by: 3 3 being isolated, shallow systems that are rainfall dependent; occurrence on alkaline shale-derived soils. Major threats and impacts: The Swartland Shale Renosterveld has been severely transformed and is severely threatened 90% has been totally transformed and remaining 10% lies in fragments across the landscape. The wetlands lying within this vegetation type have similarly been affected, largely by cultivation and livestock grazing. STRANDVELD DEPRESSION There are numerous strandveld depressions, located immediately north of the lower Berg River. They are a mixture of vegetated and un-vegetated wetland systems. Those that are vegetated are dominated by grasses (such as Cynodon dactylon), Sarcocornia spp., and various restios, rushed and sedges. These depressions are characterised by: 3 being isolated and reliant on rainfall (those north of the Berg River probably also filled as water levels rise in this water discharge area); 3 3 occurrence on neutral sands or granite derived soils; being predominantly saline systems. Major threats and impacts: Although there are some protected areas within the strandveld, the strandveld depressions have been severely impacted by agricultural activities near the coast. Salt-mining, on a small or large scale has led to physical modification of depressional wetlands. Due to their location near the coast, these systems are also particularly threatened by resort, housing, and urban development, especially in the southern portion of the domain. FISH SPECIES The primary catchment of the Olifants-Doring river system is critical in terms of freshwater fish conservation. It has the highest number of endemics in southern Africa, and is “the freshwater fish hotspot” nationally. The catchments are home to 10 endemic fish species of which two are Critically Endangered and a further five are Endangered. The Berg River system is home to the Berg River redfin (Pseudobarbus burgi) which is found only in this river system and which is also Critically Endangered. Recent genetic research has indicated that the Verlorenvlei redfin is a new species that is restricted to this river system. Other species within these catchments include the Cape kurper (Sandelia capensis) and the Cape galaxias (Galaxias zebratus). Genetic studies have shown that Sout River Galaxias, is in fact a number of separate and undescribed species. The Berg-Breede whitefish (Barbus andrewi), one of the larger species, is extinct in the Berg River, and its long-term survival is dependent upon conserving populations in the Breede River catchment. 7 47 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Major threats and impacts: The main threats to these fish are the presence of alien invasive fish species, in particular the three bass (Micropterus spp.) species, unsustainable levels of water abstraction and habitat degradation mainly as a result of agricultural activities. Current obstacles include low levels of awareness amongst riparian landowners and anglers, unsustainable levels of water abstraction and the continuing illegal stocking of fishes into dams and rivers, leading to new introductions of harmful alien species such as carp and sharptooth catfish in the river system in the last 10 years. SOME ENDEMIC FISH SPECIES Berg River Redfin (Pseudobarbus burgi) This endangered fish species are found in tributaries of the Berg River and Verlorenvlei in habitats that varies from clear mountain streams to deep, still, vegetated pools in river in the lowlands. Feeds form the bottom on invertebrates, algae and detritus. Some scientist believes that the species found in the Verlorenvlei may be a new species, but this needs still to be confirmed Clanwilliam Yellowfish (Barbus capensis) The impressive Clanwilliam Yellowfish is only found in the Olifants-Doring River System and is the Western Cape's largest indigenous freshwater fish. This magnificent gamefish, which in breeding colour looks like a bar of gold, has sadly undergone major declines in its distribution range and abundance since the 1930s. These declines have been caused by invasive fishes (primarily smallmouth bass) and habitat degradation due to excessive water-use from rivers, bulldozing of rivers and the inappropriate use of fertilizers and pesticides. Clanwilliam yellowfish are currently listed as Vulnerable by the IUCN and breeding populations are only found in the Olifants Gorge and some tributaries where alien fishes are absent and aquatic habitat is healthy. Several recent conservation and water resource management measures hold substantial promise for the future of the species, including the establishment of the Groot Winterhoek Freshwater Stewardship Corridor (Maree & Vromans 2010) 7 48 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 2.9.3 ESTUARIES ECOSYSTEM SERVICES Estuaries provide a range of services that have economic or welfare value. In the Berg Estuary, the most important services are commercial fishing, recreation and tourism, salt production and potentially Carbon sequestration. From a biodiversity perspective the estuary is a nursery ground for various fish species that are dealt with in more detail below and, importantly, provides 60% of the available estuarine habitat on the West Coast. It is estimated that the nursery value of the estuary is in the region of R 9 million per year. Additionally this estuary is a popular tourism destination and is very popular among recreational fishermen. The recreational value of the estuary is estimated to range between R 10-20 million per annum (Bergrivier Estuary Situation Assessment). ESTUARINE TYPES According to the National Wetland Inventory Classification System (NWICS), estuaries are defined as “…partially enclosed ecosystems that are permanently or periodically connected to the ocean, which are influenced by tidal fluctuations and within which ocean water is at least occasionally diluted by fresh water derived from surface or subsurface land drainage.” The length and breadth of an estuary may be determined from the Reserve Determination Methods for estuaries (under the National Water Act 36 of 1998), which define the geographical boundaries of an estuary as: 3 3 3 Downstream boundary: the estuary mouth; Upstream boundary: the extent of tidal influence; i.e., the point up to where tidal variation in water levels can still be detected or the extent of saline intrusion, whichever is furthest upstream; Lateral boundaries: the 5m Above Mean Seal Level (AMSL) contour along each bank has been recommended as a useful preliminary management boundary to define the whole estuary, including its upstream extent, particularly where data on saline extent are limited (Lara van Niekerk, CSIR, pers.comm.). In the present study, estuarine lateral extent was been mapped based on extant plant communities, with the 5m contour being represented as far as these data allow as a planning / conservation tool and to assist in setting ecological setbacks from estuaries (Job et al 2007). THE BIODIVERSITY IMPORTANCE AND UNIQUE CHARACTER OF THE BERG RIVER ESTUARY The C.A.P.E. estuaries conservation plan (Turpie and Clark, 2007) selected for the Bergrivier estuary for partial EPA status. This means that at least one side of the system should be managed as a sanctuary, receiving protection from all consumptive use. This is a very important estuary in terms of its contribution to protecting both nationally and internationally important biodiversity. At the very least the area should be proclaimed or partially proclaimed an Estuarine Protected Area as it has no formal conservation status at the present time See Table 5 below. TABLE 5: THE SIZE, IMPORTANCE AND CONSERVATION OF THE BERG RIVER ESTUARY (JOB ET AL 2007) Estuary Municipal jurisdiction Approx size (ha) Protection status Berg River Estuary Bergrivier / Saldanha Bay 7 770 None / Ramsar site Priority rank in SA 3rd Recommend status* Averaged integrity Partial EPA 0.5 *PA = Protected Area, EPA = Estuarine Protected Area, EMA = Estuarine Management Area 7 49 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The Berg River estuary extends for approx. 69 km upstream from its mouth although seawater does not penetrate this far upstream. It is a river dominated estuary, and because of its physical type, rarity, large size and high diversity and abundance of biota, the estuary is rated among the top three estuaries in South Africa in terms of its conservation importance (Turpie et al. 2002, Turpie et al. 2004). The tidal range of the estuary varies between 0.2-1.5m. The impact of tides weakens rapidly upstream of the mouth with inter-tidal areas occurring for the most part downstream of the Railway Bridge. The main channel is 100-200m wide and is 3-5m deep on average but up to 9m deep in certain areas. The estuaries shallow gradient and extensive floodplain make it unique. The inundated floodplain in particular is a special feature of the Berg River Estuary. It is 2 1.5-4.0km wide and covers an area of 61 km . Much of the lower floodplain has been transformed to evaporation dams for salt production. In 1966 a new estuary mouth was cut and the mouth dredged to a depth of 4 m to allow boat access, these alterations are not seen as detrimental except at the mouth (Clark & Ractcliffe 2007). The natural runoff from the catchment amounts to 931 Mm3.y-1, nearly half of which (45%) is generated in the top three quarternary catchments which cover 7% of the area and are located in the mountainous upper reaches of the Berg River. Water flow into the estuary has been severely impacted by the construction of rivers, agricultural abstraction and invasion of the river by alien invasive plants. It is estimated that the combined effect has resulted in 3 -1 a reduction in runoff amounting to 682 Mm .y as a result flow and quality of water have been adversely impacted. Additional impacts include urban development, encroachments of agricultural fields, overexploitation of fish, increased siltation, reduced volumes of freshwater flowing into the estuary (Job et al 2009). The estuary is fed by surface flows while the floodplain also benefits directly from rainfall. Groundwater is found at depths of between 36m below the floodplain and is discharged into the estuary continuously. The discharge does not appear to have been impacted by the construction of large dams in the upper reaches of the river (Clark & Ractcliffe 2007). There are five critical components of the flow regime that regulate ecological processes in rivers: magnitude, frequency, duration, timing (or predictability) and rate of change (flashiness) of hydrological conditions (Poff et al. 1997 in Clark & Ractcliffe 2007). According to Job et al 2007, the Berg River estuary is classified as a permanently open, cool temperate system. The classification of estuaries has been further improved by Job et al 2007 into three broad categories namely: 3 3 3 Arid estuarine channels and depressions; Cape estuarine channels and depressions (the Berg River Estuary falls in this category), and; Cape estuarine bays. CAPE ESTUARINE CHANNELS, BAYS AND DEPRESSIONS The Berg River Estuary is typical of this category and has a high salinity due to its permanent connection with the sea. As an estuary, it is a mixture of estuarine channel and estuarine depression wetlands. Typical plant species: Zostera capensis (aquatic), Chenolea diffusa, Sarcocornia perennis, S. pillansii, S. capensis, Salicornia meyeriana, Triglochin striata, Triglochin bulbosa, Plantago crassifolia, Ruppia cirrhosa, R. maritima, Spergularia media, Juncus kraussii, Sporobolus virginicus, 7 50 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Cotula coronopifolia, Cotula filifolia, Limonium equisetinum, L.decumbens, Samolus porosus, and Puccinellia angusta. On drier edges, Lycium ferocissimum, Lycium cinereum, and Exomis microphylla may be prominent. Special plant species: None known; not noted for rare species or endemics in this region. Major threats and impacts: As noted above, although some of these estuaries are protected they are vulnerable to impacts of groundwater abstraction. This is particularly true of the Berg River estuary. Other impacts include salt mining and processing plants, urban development and encroachment of cultivated fields. These estuaries occupy land that is very valuable in terms of resort, housing estate, and golf course development and, although their presence and good condition inflate land prices and aesthetic value, these systems are threatened by the encroachment of these developments. Estuaries are vulnerable to rising sea levels, and sedimentation from upstream erosion. PLANT COMMUNITIES OF THE ESTUARY MICROSCOPIC ALGAE The micro algal community of the Berg estuary appears to be typical of South African Estuaries and includes species that are found in the water column (phytoplankton) and on the plant material, mud and stones within the estuary (Clark & Ractcliffe 2007). They are by far the most important food source for other life in the estuary. HIGHER PLANTS The plant communities are largely distinguishable in terms of sub tidal, intertidal, and floodplain communities. Sub tidal vegetation is dominated by eel grass Zostera capensis in the lower estuary, which is replaced by fountain grass Potamageton pectinatus in the less saline upper reaches. The presence of these two plant communities is strongly linked to the saltiness of the water. On elevated areas the eel grass gives way to cord grass Spartina maritima, soutbos Bassia diffusa and daisies Cotula spp and brakbos Sarcocornia perennis. Above the intertidal area the marsh is dominated by Brakbos and where the marsh is inundated during winter by bare patches. Further upstream in the fresher reaches of the estuary, the narrow intertidal and adjoining floodplain areas are mainly occupied by sedge marsh, dominated by Schoenoplectus spp. and Cyperus textiles or by taller reed marsh, mainly stands of Phragmites australis. Behind the reed marsh, many of the inner river bends also contain extensive lowerlying sedge marshes that are flooded during winter, creating sheltered backwater areas (Clark & Ractcliffe 2007). In the uppermost reaches of the estuary, the riverbanks are lined by riparian woodland, with species such as Salix mucronata, Rhus tomentosa, Olea spp. and Metrosideros angulstifolia. The riparian area is invaded by Eucalyptus, Acacia and Populus spp. ANIMALS INVERTEBRATES The invertebrate communities include the zooplankton that occur in the water column and those species that occur in the bed and on other surfaces in the estuary. The dominant form of invertebrate in the Bergrivier Estuary are copepods (~98%) the balance being made up of fish larvae, brachyuran larvae, mysid shrimps, amphipods and other organisms. The zooplankton community is typical of freshwater rich estuaries. Invertebrate community structure is influenced primarily by salinity and sediment characteristics, both of which are influenced by flow. Abundance of invertebrates is influenced by sediment more than salinity. The highest densities are associated with intermediate sediment size. If sediments are too coarse tunnels collapse and there is a relative scarcity of organic material, whereas very fine sediments are not well oxygenated and require species to have specific adaptations to 7 51 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 survive. Water plants also affect species abundance inasmuch as they provide a variety of habitats for species to live in. The microscopic algae are the most important community in the food web in the estuary and provide all the required food for the invertebrates. The presence and abundance of invertebrates is positively correlated to the abundance of microscopic algae i.e. the more algae the more invertebrates (Clark & Ractcliffe 2007). VERTEBRATES OF THE BERGRIVIER ESTUARY FISH The most abundant fish species in the estuary is the southern mullet or harder, Liza richardsonii (see photo), with the estuarine Round-herring Gilchristella aestuaria being second most abundant. These, together with bald goby Caffrogobius nudiceps, silverside Atherina breviceps, sand goby Psammogobuius knysnaensis and Mozambique tilapia Oreochromis mossambicus are the dominant species present in the estuary. The balance is made up of marine species that occur in estuaries. Interestingly even though marine species are in the minority they make up in excess of 80% of the biomass of fish within the system (Clark & Ractcliffe 2007). . Relative abundance can however shift quite dramatically from year to year. In some years 75% of species present are marine, in other years this is reversed with 75% of species being estuarine. Much of the variability is due to major fluctuations in the presence and abundance of the southern mullet. This species is typically most abundant in the lowest 10km of the estuary but may be found throughout the estuary at any time. Other such opportunistic species, including elf Pomatomus saltatrix and white stumpnose Rhabdosargus globiceps, are confined to the lower more saline reaches and are more common in summer than winter. Gilchristella (entirely resident in estuaries) occurs throughout the estuary during all seasons but is most abundant between 15-50 km upstream. Other estuarine residents (not confined to estuaries), such as Atherina breviceps and Psammogobuius knysnaensis, tend to be most abundant in the lower 30-40 km of the estuary, some showing a distinct preference for higher salinities. The flathead mullet Mugil cephalus, is present throughout and depends on the estuary as a nursery area. Freshwater species, viz. tilapia Oreochromis mossamicus and carp Cyprinus carpia (both alien invasive) are found in the upper reaches in winter and tend to move down into the lower estuary during the dry summer months. In terms of the food that these fish feed on, four distinct groups are present. The largest percentage (80% of the mass of fish present in the estuary) of fish feed on microscopic algae in the water column and detritus and include; the southern mullet, flathead mullet, tilapia and carp. Zooplankton feeders are in second place (10% of the mass of fish present) and include Atherina breviceps and Gilchristella aestuaria. Fish feeding by filtering the sediments for food particles or skimming organisms off the surface of the mud or sand and those that specialise in eating other fish make up 5% of the mass of fish present. The 7 52 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 dominant filter feeding species are the gobies Psammogobius knysnaensis, Caffrogobius nudiceps and C. gilchristi and white steenbras Lithognathus lithognathus. The specialist fish eaters are the elf Pomatomus saltatrix and leervis Lichia amia (Clark & Ractcliffe 2007). Fresh water flowing into an estuary such as this is very important to fish. They use estuary specific smells in the freshwater to navigate their way into the estuary. Most of these fish move into the estuary during the low flow periods of summer. It is therefore extremely important to retain the base flow of the river to ensure that fish can successfully navigate their way into the estuary. Reduction in flows would have significant consequences for fish fauna of the estuary (Clark & Ractcliffe 2007). BIRDS The presence of birds, in particular wading birds, makes the Berg River Estuary one of the most important estuaries in South Africa. The special attributes related to its size, habitat importance and zonal type rarity has resulted in the Berg River rd Estuary being rated the 3 most important estuary in the South African context. The highest recorded density of birds recorded on the East Atlantic Seaboard was from the Berg River Estuary, by number (90%) most of these are migrant waders from the Northern Hemisphere. It is an important estuary for the young of these migrants as an over-wintering ground. However it is very important in terms of some nationally important birds species too. To date 127 species have been recorded, of which 93 are specialised waterbirds. The average number of birds present in the estuary in mid summer is 14 400 individuals, the numbers are reduced to an average of 1 600 birds by mid-winter. The estuary supports large numbers of flamingo, duck species (such as the Cape teal, opposite page), white breasted and reed cormorants, darters and pelicans (right). In terms of the numbers of birds present in winter the bird population is dominated by greater & lesser flamingo's, ducks, red knobbed coot, waders and other rails. The presence of these birds is closely linked to the type of habitat that they prefer and saltiness of the water. At the mouth of the estuary the population is dominated by cormorants, gulls and terns. Just inland in the lower estuary flamingo's and waders are common in summer and flamingo's, waders and coots in winter. In the upper estuary the population is made up of ducks, flamingo's and coots primarily. The primary reason for this distribution of species throughout the estuary is linked to the saltiness of the water and the dependence of certain species on a supply of fresh water which decides the presence or absence of their favoured food in a given habitat. As a rule of thumb the tolerance of bird species to salt increases with proximity to the sea. In years of good rainfall when more fresh water flows into the estuary certain species such as shelduck, reed cormorants, freshwater terns and pelicans become more abundant. An estuary is a magnet for birds because it is such a productive ecosystem, bird numbers are therefore good indicators of the productivity or availability of food in the estuary, the higher their numbers the higher the productivity of the ecosystem. 7 53 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 ENVIRONMENTAL LEGISLATION 3.1 CONSTITUTION OF SOUTH AFRICA The Constitution of the Republic of South Africa (Act 108 of 1996) in particular, the Bill of Rights stipulates that: “Everyone has the right (a) to an environment that is not harmful to their health or well-being; and (b) to have the environment protected, for the benefit of present and future generations, through reasonable legislative and other measures that (i) prevent pollution and ecological degradation; (ii) promote conservation, and (iii) secure ecologically sustainable development and use of natural resources while promoting justifiable economic and social Development” (section 152). Section 152 of the Constitution, together with Schedule 4 and 5 stipulates that local government must… 3 3 3 3 3 Provide democratic and accountable government for local communities; Ensure the provision of services to communities in a sustainable manner; Promote social and economic development; Promote a safe and healthy environment and Encourage the involvement of communities and community organizations in the matters of local government. Schedules 4B and 5B contain 'local government matters” which are the responsibility of local government and contain the following environmental matters: 3 Air pollution, fire-fighting services, local tourism, municipal health services, storm water management in built up areas, water and sanitation services (limited to potable water systems and domestic waste-water and sewerage disposal systems), beaches, cleaning, local amenities, municipal parks and recreation, noise pollution, public places and refuse removal, refuse dumps and solid waste removal. 3.2 THE WESTERN CAPE CONSTITUTION The Constitution of the Western Cape (Act 1 of 1998) makes provision for the establishment of and principles governing a Commissioner for Environment (Section 71). Secondly, two of the directive principles of provincial policy (Section 81) relate to matters concerning the environment. The Western Cape government must adopt and implement policies to ensure human welfare and policies that will achieved the following: The protection of the environment in the Western Cape, imcludig its unique flora and daun, for the benefit of present and future generations and to ensure protection and conservation of the natural historical, cultural historical, archaeological and architectural heritage of the Western Cape for the benefit of the present and future generations. 3.3 NATURAL RESOURCE MANAGEMENT LEGISLATION 3 National Environmental Management Act The National Environmental Management Act (NEMA) (Act 107 of 1998) provides for co-operative environmental governance by establishing principles for decision making on matters effecting the environmental, institutions that will promote co-operative governance and procedures for co-ordinating environmental functions exercised by organs of state, and to provide for matters connected thereto. 7 54 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Chapter 1 (2) of NEMA contains a set of core environmental principles that are applicable to all organs of state that may significantly affect the environment. Local Government is required to incorporate these into any policy, programme, plan or any decision made that may have a negative impact on the environment. Environmental Impact Assessment (EIA) Regulations under Section 24(5) of NEMA were promulgated on 21 April 2006 (Government Notice R 385, No. 386, and No. R 387). and come into affect on 1 April 2007. Everyone wishing to undertake an activity identified in terms of Section 24(2)(a) and (d) of NEMA will need to obtain authorisation from the competent authority via the prescribed EIA process. 3 National Environmental Management: Waste Act The National Environmental Management: Waste Act, 2008 (Act 59 of 2008) describe activities in respect of which a waste management licence in required according to Section 20(b). Listed activities are divided into two categories and to each category has its prescriptive process to apply for environmental authorization. Implication for BRM Ensure that all sewerage plants and waste management sites and associated infrastructure have the necessary environmental authorization. 3 National Water Act The National Water Act (Act 36 of 1998) deals with water resource management and the sustainable use therof. The Act provides for the integrated management of all aspects of water resources and the delegations of management to a regional or catchment level to ensure everyone to participate. Sustainability and equity are identified as key principles driving protection, use, development, conservation, management and control of water resources. 3 Water Services Act The Water Services Act (Act 108 of 1997) deals with the rights of access to basic water supply and basic sanitation and sets national norms and standards for tariffs. The Water Services Act emphasise to the local authority to prepare a water services development plan as part of their IDP. 3 Minerals and Petroleum Resources Development Act The purpose of the Minerals and Petroleum Resources Development Act (Act 28 of 2002) is to make provision for equitable access to and sustainable development of the country's mineral and petroleum resources. The Act therefore deals with prospecting and mining rights. Every person who has applied for a mining right must conduct an environmental impact assessment (EIA) and submit an environmental management program (EMP). 3 National Heritage Resources Act The purpose of the National Heritage Resources Act (NHRA) (Act 25 of 1999) is to introduce an integrated and interactive system for the management of the national heritage resources in South Africa. The Act also serves to empower civil society to nurture and conserve their heritage resources and to provide for the protection and management of conservation-worthy places and areas by local authorities. 7 55 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 3 National Forests Act The purpose of the National Forests Act (act 84 of 1998) is amongst others to promote the sustainable management and development of forests for the benefit of all. 3 National Veld and Forest Fire Act The purpose of the National Veld and Forest Fire Act (No 101 of 1998) is to prevent and combat veld, forest and mountain fires in South Africa. The Greater Cederberg Fire protection were registered in 2005 with the Minister of Water Affairs and Forestry. Implications for BRM All state land must join the local Fire protection Association and therefore the BRM must become a member of the Greater Cederberg Fire Protection Association. 3 Marine Living Resource Act The Marine Living Resource Act (No.18 of 1998) provide for the conservation of the marine ecosystem, the longterm sustainable utilization of marine living resources and the orderly access to exploitation, utilisation and protection of certain marine living resources; and for these purposes to provide for the exercise of control over marine living resources in a fair and equitable manner to the benefit of all the citizens of South Africa; and to provide for matters connected therewith. 3 Land Use Planning Ordinance The Land Use Planning Ordinance (Ordinance 15 of 1985) serves to regulate land use planning and to provide for matter incidental thereto. The Ordinance provides for the preparation and submission of Structure Plans and Implications for BRM Every local authority shall comply and enforce compliance with the provisions of the Ordinance. Zoning Schemes, and provides stipulations in terms of the subdivision and rezoning of land. The Land Use Planning Ordinance Amendment Act (Act 2 of 2004) extends to 19 years the period during which owners of land may exercise land use rights. 3 Nature and Environmental Conservation Ordinance The Nature and Environmental Conservation Ordinance (ordinance 19 of 1974) serves to consolidate and amend the laws relating to nature and environmental conservation. The Act provides for the protection of wild animals, fish in inland waters and flora, and requires that a permit be obtained to undertake certain actions regarding the latter natural resources. 7 56 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 PLANNING FRAMEWORKS 4.

These are the Western Cape Environmental Implementation Plan, Western Cape Provincial Spatial Development Framework, Guidelines for Resort Developments in the Western Cape, Guidelines for Golf Courses, Golf Estates, Polo Fields and Polo Estates in the Western Cape, Western Cape Provincial Urban Edge Guideline, Western Cape State of the Environment Report, Growth Potential of Towns in the Western Cape, Western Cape Provincial Growth and Development Strategy, A Settlement Framework for the Western Cape Province, Green Paper, Bioregional Planning Framework for the Western Cape Province, Draft Coastal Zone Policy for the Western Cape, The Integrated Coastal Management Programme for the Western Cape, Western Cape Promotion of Sustainable Development Bill (Preliminary outcomes of the Provincial Law Reform Process), Ikapa Elihlumayo A Framework for the Development for the Development of the Western Cape Province (2004-2007), Micro Economic Development Strategy for the Western Cape (2005), Strategic Infrastructure Plan for the Western Cape Province (2005), Guidelines for environmental decision making by Municipalities in the Western Cape (West Coast District Authority 2006). 4.4 LOCAL FRAMEWORKS The Integrated Development Plan (IDP) The Bergrivier Integrated Development Plan was approved during May 2007. During the 3 rd review of this plan the following strategic objectives were identified by the stakeholders as priorities, that need specific attention: 7 3 Motivated and represented employees through developing skills and empowerment and effective utilisation of personnel; 3 3 3 Management and protection of assets; 57 Effective communication; Qualitative and balanced service delivery; BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 3 3 3 3 3 3 3 Accountable and transparent governance; Effective Customer Care; Effective Infrastructure maintenance and development; Effective policing; Eradication of housing backlogs; Addressing ward based needs; Local Economic Development (Bergrivier Municipality, 2010). The Bergrivier Spatial Development Framework (SDF) The Bergrivier Spatial Development Framework was completed in 2008 and proposed spatial guidelines to take effect within the municipal area in order to direct future spatial interventions as a result of growth, development and policy and to reduce developmental disparities. Lower Berg River Sub-Regional Structure Plan (1999) The purpose of this structure plan is to provide in the needs of both the rural and urban populations of the region in such a manner that the sustainable use of the environment and resources will be ensured. The following strategies have been formulated in terms of the plan: 3 3 3 Development guidelines of the urban component (Velddrif, Laaiplek and Dwarskersbos) as well as the transitional zone to the agricultural area; The proclamation of a Protected Area to protect the river and improve management of the river banks; Research is necessary to be formulated hydrographical management guidelines for the Berg River. Verlorenvlei Local Structure Plan (1996) Policies are recommended to fulfil the above aims and to provide decision-makers with a framework for the management of development in this unique environmental asset. The plan also takes into account the roles of agencies such as WWF-SA, Wildlife Society and Botanical Society. CapeNature is the principal stakeholder in this process, as the management authority for Verlorenvlei. Sub-Regional Structure Plan for the Coastal Area Dwarskersbos to Olifants River (1992) The structure plan comprises of a series of plans that indicate an over-arching land-use pattern, with appropriate proposals and guidelines for the above issues. The following were addressed in this plan: 3 3 3 3 3 Public access to the coast; Achieving a compromise between conservation and development; Identifying conservation-worthy and sensitive areas; Identifying potential areas for development; and Managing state land along the high-water mark. Sub-Regional Structure Plan for the Coastal Area Velddrif to Bokpunt (1990) The primary objective of the structure plan is to provide a framework for harmonious development and for preventing potential conflicts between the interests of urbanisation, recreation and conservation. The structure plan comprises of a series of plans that indicate an over-arching land-use pattern, with appropriate policies and principles. Specific issues relating to recreational developments are addressed. 7 58 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Porterville Mountain Development Plan The development plan, which serves to achieves sustainable utilisation of the area through spatial planning and management guidelines, that focus on aspects such as housing and settlement, human welfare, service provision,land reform, conservation, promotion of tourism and safeguarding the agricultural integrity. The plan identifies short term and medium term priorities for implementation (West Coast District Municipality 2002). Piket-Bo-Berg Development Plan The development plan, which serves to achieves sustainable utilisation of the area through spatial planning and management guidelines, that focus on aspects such as housing and settlement, human welfare, service provision, land reform, conservation, promotion of tourism and safeguarding the agricultural integrity. The plan identifies short term and medium term priorities for implementation (West Coast District Municipality 2002). Greater Cederberg Biodiversity Corridor The Greater Cederberg Biodiversity Corridor Plans include the following: GCBC Planning Phase report, Spatial Planning, Technical Report, GCBC Economic pre-feasibility study, GCBC Community Engagement study, GCBC Biodiversity Profile and GCBC Regional Tourism Development Plan. These documents are available from the CapeNature office in Porterville. Protected Area Management Plans Protected Area Management Plans generally provide more detail on the reserve itself and prescribe actions to managed biodiversity but also include broader contextual information such as tourism opportunities, local economic development and Community Based Natural Resource Management (CBNRM). 4.5 BIODIVERSITY MAPS 4.5.1 NATIONAL BIODIVERSITY PLANNING MAPS MAP 10: NATIONAL SPATIAL BIODIVERSITY ASSESSMENT 7 59 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 4.5.2 CRITICAL BIODIVERSITY AREAS (CBA) MAP The Critical Biodiversity Areas Map for the BRM was produced through a systematic biodiversity planning process at a scale of 1:10 000. It should be used to assess and identify those areas in the municipality that require conservation to ensure the persistence of species and habitats, as well as areas for ecological and evolutionary processes that maintain biodiversity. This is a crucial tool that should be used to guide sustainable development and align landuse management with the critically important elements of biodiversity in the municipality. This is an especially important forward planning document that should be used to design response strategies to global climate change. Importantly the map represents the most efficient (in terms of the space allocated to conservation) way to conserve the important features of biodiversity in the landscape. Definitions of the Critical Biodiversity Areas Map Categories According to Maree and Vromans, 2010. Protected Areas - These are terrestrial or marine areas that are formally protected in terms of the National Environment Management: Protected Areas Act (Act No. 57 of 2003) and/or Marine Living Resources Act (Act No. 18 of 1998). Critical Biodiversity Areas - Critical Biodiversity Areas are those areas required to meet biodiversity thresholds. They are areas of land or aquatic features (or riparian buffer vegetation alongside CBA aquatic features) which must be safeguarded in their natural state if biodiversity is to persist and ecosystems are to continue functioning. These Critical Biodiversity Areas incorporate: i) areas that need to be safeguarded in order to meet national biodiversity pattern thresholds (target area), ii) areas required to ensure the continued existence and functioning of species and ecosystems (including the delivery of ecosystem services); and/or iii) important locations for biodiversity features or rare species. The CBA network represents the most land-efficient option to achieving all biodiversity targets. Ecological Support Areas - Ecological Support Areas (ESA) are supporting zones required to prevent the degradation of Critical Biodiversity Areas and Protected Areas. An ESA may be an aquatic feature, e.g. a specific river reach that feeds into an aquatic Critical Biodiversity Areas; or a terrestrial feature, e.g. the riparian habitat surrounding and supporting Critical or Other Ecological Support Area rivers or wetlands. Ecological Support Areas can be further subdivided into Critical Ecological Support Areas (CESA) and Other Ecological Support Areas (OESA). Critical Ecological Support Areas are those aquatic features (with their terrestrial buffers) which fall within priority sub-catchments, whose protection through wise management is required in order to support the aquatic and terrestrial CBA. An example might be a river reach which feeds directly into a CBA. Other Ecological Support Areas are all remaining aquatic ecosystems (not classed as CESA or CBA) (with their terrestrial buffers) which have a less direct impact on the CBA, e.g. an isolated and degraded wetland which although geographically separated from a CBA, still contributes to ecological processes such as groundwater recharge which indirectly impacts on CBA downstream. Other Natural Areas Other Natural Areas are those areas of natural or near-natural vegetation identified on the map whose safeguarding is not required in order to meet national thresholds. A site can only be classified as an Other Natural Area if the extent of the ecosystem represented by that site exceeds its threshold. In such cases, some loss through conversion of the natural state of that ecosystem may be allowed. It is important to note that if all earmarked Critical Biodiversity Areas are not protected it will result in certain Other Natural Areas having to be reclassified as Critical Biodiversity Areas in order to meet thresholds. Therefore, in all decisionmaking, the precautionary principle needs to be applied. No Natural Remaining Areas - No Natural Remaining Areas are those sites identified on the CBA Map, which have been irreversibly transformed through development (e.g. urban development, plantation, agriculture) or poor land management (e.g. erosion) and as a result, no longer contribute to the biodiversity of the area. However, there are a few exceptions to the classification of transformed lands. Some small patches of cultivated or otherwise disturbed land have been classified as ESA or even CBA. The reason is that these areas still support biodiversity in some way (e.g. strips of natural veld growing between rooibos shrubs can still form important stepping stones for species to migrate, which means that this kind of land-use provides a corridor which is classified as a Critical Biodiversity Area). Such areas (transformed or degraded lands which have nonetheless been classified as CBA) require some form of safeguarding, e.g. no further hardening of surfaces should be permitted. 7 60 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 TABLE 6: LAND COVER CATEGORIES FOR THE BRM (Natural refers to pristine natural vegetation and aquatic features. Near-natural includes those areas where some degree of degradation is evident but where restoration and / or rehabilitation should be considered, e.g. moderately disturbed vegetation, moderately infested with invasive alien plants. Degraded lands are those areas which are severely impacted (usually due to dense invasive alien plants) and which can be rehabilitated, but at great cost. It is important to note that alien invasions were not mapped at a high accuracy for the entire domain. It is therefore likely BRM that the actual levels of invasion are far higher than recorded below. Furthermore, degraded areas are likely to increase in extent over Natural 40.43% time, while natural and near-natural are likely to decrease. Near natural 3.91% Production areas are agricultural lands which are currently under Degraded 6.32% production (including fallow fields less than 10 years old). Production 48.02% Transformed refers to land which has undergone irreversible Transformed (ex cluding urban) 1.19% development, and includes the urban built-up environments and Urban 2.03% infrastructure (such as dams) and mining areas (Maree and Vromans, 2009).

Biodiversity areas identified as important should be maintained in their present state. Further development should be focussed in degraded and transformed areas. 63 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 TABLE 8: THE DESIRED MANAGEMENT OBJECTIVES FOR THE CBA'S OF THE BRM CBA Map Category Desired Management Objective Critical Biodiversity Areas (terrestrial), Critical Biodiversity Areas (aquatic feature and buffer) and Protected Areas Maintain natura l land.

Favoured areasor areas fordevelopment. development Municipalities have a very important role to play in ensuring that appropriate environmental authorisations are issued and that the correct procedures are followed in the development application process. In terms of the environmental authorisation process the municipality should: 3 Only issue an approval for a development once all other applications have been authorised (e.g. environmental authorisations for development rights from DEA & DP or water licences from DWA, or 3 In responding to a development application, make it explicit that work can begin only once other authorisations are in place. 64 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 INSTITUTIONAL ARRANGEMENTS 5.1 INSTITUTIONAL STRUCTURE Municipal interaction with the NEMA EIA process, rezoning applications and subdivisions are handled by the town planning section of the Administrative Service Directorate. The Municipality doesn't have a dedicated section or staff component to deal with environmental and biodiversity management and these aspects are not contained in the IDP even though it is required by national legislation. It is clear that an environment management section should be established within the municipality and posts built into the current organogram. Because of the size of the BRM it is recommended that three posts are created, a qualified Nature Conservator supported by two extension officers would be ideal. The biodiversity of the municipality is of international importance and there are very real threats to its survival. As such these posts should be advertised as soon as possible and appointments made. The key performance areas of appointed staff could include biodiversity inputs and comments from a municipal perspective in the EIA process, conservation planning, biodiversity management, fire management activities, the eradication of alien invasive species, awareness raising and environmental education and community based natural resource management initiatives. 5.2 MAINSTREAMING BIODIVERSITY INTO GOVERNANCE Historically biodiversity management was focussed on the establishment of formal protected areas, the erection of fences to keep people out and law enforcement actions to ensure that biodiversity was protected. However it soon became apparent that upwards of 80% of national biodiversity occurred on private property. This realisation refocused conservation effort to include off reserve conservation interventions and management. The planning and implementation to support this new focus took the form of the Cape Fine Scale Planning, Greater Cederberg Biodiversity Corridor and the CapeNature Stewardship Programme. The greatest threat to biodiversity within the municipality is linked to agricultural development. Mainstreaming of biodiversity conservation into the agricultural sector was seen as the primary means of addressing off reserve conservation in an environment dominated by agricultural development. Two projects were launched by the Greater Cederberg Biodiversity Corridor in collaboration with Potatoes South Africa and the South African Rooibos Council in the pursuit of the objective. They became known as the Biodiversity Best Practices for Potato Production in the Sandveld and the Right Rooibos project. The focus of these projects has broadened and become driven by a vision for a sustainable agricultural future. As such they are a perfect platform for the municipality to engage with the rural community is the drive t o w a r d s s u s t a i n a b i l i t y. Opportunities should be sought to link biodiversity 65 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 INSTITUTIONAL ARRANGEMENTS conservation, the provision of basic services and socio-economic upliftment to mainstreaming projects such as these. These are but two initiatives, organisations such as CapeNature, SANBI, Departments of Agriculture, Department of Water Affairs, DEA & DP and NGO's are all engaged in planning, research, implementation and the co-ordination of existing projects. The mainstreaming of biodiversity conservation into the governance structures of the municipality should be encouraged and become a standing point on Council meetings and municipal management meetings. 5.3 INTERACTIONS WITH OTHER AGENCIES The municipality should become an active participant on collaborative forums such as the Sandveld Forum, Water Users Associations and Greater Cederberg Fire Protection Association that have been created to provide a platform for collaborative management between government departments, exchange information on current projects and encourage responsible resource use and management by civil society. There are a number of existing statutory and voluntary conservation sites, environmental planning, conservation and management initiatives present within the BRM that are illustrated and discussed in the following section. 66 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 CONSERVATION IMPLEMENTATION 6.1 STATUTORY PROTECTED AREAS These are terrestrial or marine areas that are formally protected in terms of the National Environment Management: Protected Areas Act (Act No. 57 of 2003) and/or Marine Living Resources Act (Act No. 18 of 1998). Ownership nestled within governmental institutions and private landowners.

Conservancies are informal arrangements between two or more landowners to improve resource management and collaboration in a specific area. These sites are predominately owned by private landowners but institutions like CapeNature always participate in the management of conservancies.

Within the context of conservation, stewardship means wisely using natural resources on your property, protecting important ecosystems, effectively managing alien invasive species, fires, harvesting and grazing without damaging the natural vegetation. The CapeNature Stewardship Program facilitates the establishment of formal conservation areas as Contract Nature Reserves and Biodiversity Agreements on private property which are declared under the National Environmental Management Protected Areas Act. 68 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 6.3 GREATER CEDERBERG BIODIVERSITY CORRIDOR The Greater Cederberg Biodiversity Corridor (GCBC) is a landscape scale conservation initiative of global importance. It is a multi-stakeholder driven conservation intervention that aims to conserve a representative sample of biodiversity of the Cape Floral Region and the Succulent Karoo in a “lived-in, worked-in landscape”. This conservation intervention has seen the creation of a multitude of partnerships between authorities, government departments, communities, landowners, non governmental organizations and conservation agencies. MAP 13 THE GCBC PLANNING DOMAIN ” 69 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The vision of the GCBC is encapsulated by the following statement: “From Karoo to Coast, we in the Greater Cederberg Biodiversity Corridor share a common purpose for biodiversity conservation trough sustainable utilization of its unique living landscape.” This is achieved by “learning and working together” so that “all the people of the Greater Cederberg Biodiversity Corridor live sustainably with, and benefit from, their natural resources now and into the future through appropriate conservation and management of the regions unique biodiversity”. The goal of the GCBC: “In the face of climate change, effectively conserve the biodiversity of the Greater Cederberg by 2020 and beyond, and through its efforts deliver significant benefits to the people of the area.” SUCCESS STORIES The GCBC has five strategic directions within which the project is co-ordinated and managed. A few of the success stories associated with these strategic directions are: 3 Consolidate and expand protected areas in the GCBC Since the initiation of the project in 2006, formally protected areas on private property within the municipality have expanded from zero ha's to 2 060 hectares in 2010. All of these new reserves are located within the highly threatened Leipoldtville Sand Fynbos and Graafwater Sandstone Fynbos and include small fragments of critically endangered Swartland Shale Renosterveld. As such they are of immense importance in conserving a national asset of global significance. The property belonging to the BRM south of the town of Redelinghuys is one such formally protected area. This relatively small area is regarded as one of the most important sites for the conservation of rare and endangered species associated with Leipoldville Sand Fynbos. Two of the core corridors of the GCBC are partially situated within the boundaries of the BRM, the Sandveld Redelinghuys 70 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 and Groot Winterhoek Freshwater Stewardship Core Corridors. These corridors are a matrix of natural and transformed areas in a “lived-in, work-in” landscape where biodiversity conservation priorities (Critical Biodiversity Areas) are recognised as a formal land use. The aim to create connected corridors of natural vegetation across altitudinal gradients and soil types from the Olifantsberg and Piketberg Mountains to the Atlantic Ocean. The Groot Winterhoek Freshwater Stewardship Corridor aims to establish the linkage between Groot Winterhoek and the Cederberg Wilderness and aims primarily to ensure the provison of high quality and quantity of water and protect some of the most important and endangered fish species in the country. The establishment of the corridor will be used to promote the importance of ecosystem services such as the sustainable provision of high quality water through awareness, education and extension to landowners, farm workers and school children. The Stewardship model developed by CapeNature will be used to establish formal conservation areas within this corridor. 3 Industry involvement: Mainstreaming Biodiversity Conservation into the Agricultural Sector The recognition that the agricultural sector is the primary driver responsible for the loss of habitat and thus the greatest threat to biodiversity was the reason the GCBC embarked on a process to pro-actively engage with Potatoes South Africa and the South African Rooibos Council. The expansion of these two industries in the last two to three decades has seen a total transformation in the appearance of the landscape within the Sandveld. The overabstraction of water and the transformation of natural vegetation without the required authorisations is a threat that persists to this day. These projects aim to encourage producers to voluntarily adopt biodiversity best practices on their properties. The projects aim to establish a sustainable agricultural system on the producer farms and as such focus on good agricultural practice and social and economic aspects of sustainability. 3 Promote local economic development through biodiversity and to promote human well-being An opportunity for Local Economic Development (LED) was created in the Verlorenvlei catchment through the establishment and implementation of a Working for Wetlands project. This programme is managed and funded by the South African National Biodiversity institute (SANBI) and is part of the Expanded Public Works Programme (EPWP). The project aims to rehabilitate the unique Verlorenvlei system through the removal of alien invasive species and flow impediments and thereby increase the volume of water flowing out of the catchments and through restorative efforts re-instate the natural flow into the Verlorenvlei. Successes of the project: 3 Twenty six employment opportunities were created by the project per year since its inception in 2006; 3 The project is coupled to skills development and capacity building and has been successful in linking project contractors to employment opportunities in the private sector; 3 A total of 1 108.37 hectares of alien invasive species have been cleared since 2006. 71 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 3 GCBC Awareness Raising Various broad target groups (audiences) have been identified, linked to each of the strategic directions of the GCBC and include: 3 3 3 3 3 3 Expansion of Protected Areas - Landowners, farmers, farm worker groups & industries; Industry Engagement - Industry partners, landowners & farmers; Human Wellbeing - Communities, small-scale farmers, up-and-coming farmers & youth (school groups); Local Economic Development - Communities, Farmers & Local authorities; Awareness - General public & GCBC communities; Coordination - Funders, CapeNature (internal), local authorities, NGO's & CBO's. Awareness projects currently implemented within the GCBC domain: 1. Schools 3 3 The Krokkitor Schools Program (Resources developed: Krokkitor I, II, Activity Book & Puppet Show); Environmental Education Programs aligned to Environmental Calendar Days (Marine Week, Wetlands Day and Environment Day.); 3 Pilot Project: Landscape Education Program (culturalhistorical and environmental aspects) in collaboration with partners (Kalmar Lans Museum, Sweden, UCT & Living Landscapes Project and Local Schools). 2. Landowners, land users, farmers & farm worker groups 3 GCBC Outreach Program (Presentation & Booklet produced specifically to increase awareness on the GCBC on contracted Stewardship sites). Other materials from the Stewardship Program of CapeNature are incorporated (Booklet produced describing the establishment of corridors and the process where by landowners can become involved in the establishment of protected areas.); 3 A guideline has been produced for farmers/producers on the management of wetlands, and is implemented as part of the Working for Wetlands, West Coast Project Awareness Campaign and Best Practice Guidelines developed in collaboration with Potato and Rooibos Industries. 3. Communities (in the broad sense) 3 72 Damage Causing Wild Animals Outreach Program - This Program focuses on creating awareness of the GCBC, the role of predators in the environment & the benefit humans gain from the presence of predators in the environment. Interaction takes the form of questionnaires dealing with problems that are experienced within the communities and examines community perceptions. The program provides training on the legal aspects of control and best practice in terms of management and the use of deterrents to prevent damage; BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 3 An Incident Register has been produced to help record annual losses. It includes the assimilation of management actions undertaken to prevent loss. The information gathered is fed back into CapeNature whose responsibility it is to assess whether the losses experienced were appropriately addressed and/or to provide adaptive strategies to be implemented and/or to provide communities with the necessary skills and knowledge to address the challenges they face in this regard; 3 Community Knowledge Exchanges provide peer learning opportunities, such as the recent GCBC & Cape Flats Nature Community Knowledge Exchange that provided community members with a platform from which to learn, share, network and promote their communities & projects. 4. General Public (GCBC communities & broader) General awareness around biodiversity conservation in the context of landscape-scale projects, such as the Greater Cederberg Biodiversity Corridor and their importance in providing the space for adaptation and mitigation to climate change are provided through the amongst others, the following: - GCBC Website: http://cederbergcorridor.org.za/; - GCBC DVD; - Various brochures (used in conjunction with programs, exhibitions, events.); - Banners (used in conjunction with programs, exhibitions and events); - E-newsletters to partners & placed on partner websites; - Media releases produced and placed in local and regional newspapers; - Creation of various platforms and making use of partner platforms to create greater awareness of the project. 3 GCBC Coordination The project is co-ordinated through the GCBC Steering Committee and the Project Management Unit located in Porterville. The Co-ordinator Johan Burger can be contacted on 022 931 2900 . 6.4 ASSOCIATIONS Associations are an effective means of organising members around a common issue, a platform to encourage discourse and information sharing and a mouth piece through which members can pro-actively engage and be represented with/to other key stakeholders. A number of active associations are operational within the municipal boundary. 6.4.1 THE GREATER CEDERBERG FIRE PROTECTION ASSOCIATION Fire is a keystone factor in the long term survival of fynbos and the cycle of destruction, regeneration and maturation, and will prevail into the future. To survive in a fire driven system such as this, many fynbos plants and animals have evolved adaptations to respond to fire (Cowling and Richardson 1995). However as the major driving force fire can also pose the greatest threat to the biodiversity of the Cape Floral Region. If fires burn too frequently or too rarely, the plant structure, composition and ecosystem function changes for the worse. If not managed properly the favourable conditions created after the fire for the germination of alien invasive seed may have a huge impact on biodiversity in the BRM. The impacts of global climate change will exacerbate the risk of fire. This will translate into a significant management challenge for the municipality not only in terms of potential damage to the local socio-economic sphere, but for the maintenance of biodiversity as well. 73 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The Greater Cederberg Fire Protection Association (GCFPA) was registered in 2005 with the Minister of the Department of Water Affairs and Forestry. A key challenge this association is facing is in aligning its activities and actions in such a manner that it will mitigate the impacts of climate change over the coming decades. The vision of the GCFPA is to promote integrated fire management in the GCFPA in order to minimise losses to social, economic and ecological assets. This is achieved through the successful implementation of strategies focussing on fire awareness, fire prevention, fire preparedness and fire protection. Successes of this association Membership is up to 276 landowners and communities with a current size of 417 744 hectares. The growth of the association is rapid and increasing annually. Integrated fire management plans for various management units have been completed and focus on the mitigation of risk, improve awareness and implementation of appropriate ecological acceptable fire regimes. The GCFPA has recently established a partnership with Working on Fire and the BRM to appoint 22 people from Piketberg that will be trained and used as fire fighters and to perform risk mitigation work. 6.4.2 VELDDRIF HERITAGE FOUNDATION The Velddrif Heritage Foundation is registered as a Conservation Body with Heritage Western Cape. The objective of the foundation is to: 3 3 3 Protect places with historical and cultural values; Create awareness and interest in conservation amongst the general public; Provide technical assistance to the alterations and or development of conservation worthy heritage resources. Projects currently underway are the restoration of the old Laaiplek cemetery, the catalogue of old fisherman cottages and old buildings (with the assistance and help from local schools), the monitoring of new developments in order to ensure that no heritage resources are impacted on and establishment of a museum that showcases the local history 74 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 and the pelagic fish industry. 6.4.3 VELDDRIF BERGRIVIER CONSERVATION ASSOCIATION (VBRCA) This body has been active for the past 15 years, and is constituted by a wide spectrum of interested and concerned people from the town and farming communities. Various statutory organizations, such as CapeNature, DEA & DP, MCM, and the local Municipality are represented. The main goal of the Association is to focus on the status and integrity of the Berg River Estuary as an extremely sensitive and important ecological system, and to identify and bring to the attention of appropriate authorities any aspects that may threaten the integrity and functioning of the system. Some achievements in the past few years include: 3 In collaboration with a number of statutory organizations, preparation and presentation of proposals to DEA & DP for registration of the Berg River Estuary as RAMSAR Wetland (these were not successful due to the fragmented nature of authority over the Estuary, and unfortunate lack of commitment by the local Municipality); 3 Registration of a Conservancy including farms on both northern and southern sides of the Estuary; 3 Production of an information pamphlet to inform locals and tourists regarding the special features of the Estuary as a Wetland of national importance; 3 Doing the groundwork for the establishment of a Management Forum for the Estuary. 6.4.4 KROM ANTONIES WATER USERS ASSOCIATION The rains which fall on the Piketberg feed the Krom Antonies River which has sustained farming in the fertile Moutonshoek Valley for 300 years. The Piket-Bo-Berg and the Moutonshoek Valley produce export fruit, nuts, olives, potatoes, proteas and world class horses, and provide work and a livelihood for hundreds of local people. The Krom Antonies River feeds the Verloren River which runs past Redelinghuys on its way to the sea. This water constitutes 60% by volume of that received by the Verlorenvlei, which forms an estuary at Elands Bay and functions as a nursery for the local fishing industry. The Krom Antonies Water Users Association has been established in collaboration with the DWA to manage this very limited and important resource through a community-based structure. 6.5 SUSTAINABLE AGRICULTURAL “BEST PRACTICES” 6.5.1 SUSTAINABLE ROOIBOS PRODUCTION “RIGHT ROOIBOS” The goal of the Right Rooibos Initiative is to: 75 3 Ensure sustainable development of the Rooibos industry through the protection and development of ecological, social and financial resources; 3 To determine and implement sustainable practices throughout the industry; 3 Promote the protection of the biodiversity on private land, with or without entering into a formal agreement with authorities; 3 Implement best practices as determined by the Right Rooibos standards for Rooibos production in order to improve harmony with nature and that the BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 people working in and lived in the industry will gain financial benefit; 3 To develop a certification system that acknowledges produces that comply with the Right Rooibos standards and to create markets for sustainable certified Rooibos; 3 To develop a long term reputation of good practices for Rooibos production that is link and associated to the conservation of a Global Biodiversity Hotspot, and ethical production practices. Successes of the Right Rooibos: 3 Development of a guideline document "Biodiversity Best Practices for Rooibos Production; 3 36 Rooibos producers are currently implementing the guidelines, total area covered 95000 hectares; 3 Definite market interest in certified Rooibos - establish Right Rooibos certification, Utz Certified certification and Rainforest Alliance certification at the end of 2010; 3 Secure Landcare funding to implement an alien invasive eradication program in a CBA. In a partnership agreement between 5 Rooibos producers, Right Rooibos and Landcare. 6.5.2 BIODIVERSITY BEST PRACTICES FOR POTATO PRODUCTION IN THE SANDVELD Agriculture and in particular potato production is the core economic activity in the Sandveld area of the Western Cape. On average approximately 6500 hectares of potatoes are planted annually for the production of seed potatoes, fresh potatoes and potatoes for the processing industry (French fries and frozen products). The value of the National Industry is estimates at 9 approx. R 4.0 billion (10 ) per annum. A significant portion of this annual turnover is generated in the Sandveld with an annual turnover that can approach R400 million per annum (Calculated on 6500 ha x 40t/ha x R13/10kg), offering job opportunities to some 3 250 workers. Input costs in the Sandveld are high and have risen from R 65 000-00 p/ha last year to R105 000-00 p/ha this year primarily as a result of escalating fuel, fertiliser and crop protection costs. Climatic conditions and other farming conditions often pose great challenges to the farmer in maintaining a viable enterprise. Projections from global climate change modelling exercises conducted by the University of the Witwatersrand for the area show decreased rainfall in the interior and increased minimum and maximum temperatures which translate into less water availability and increased evapo-transpiration from the plants. These conditions pose a significant risk to the business and biodiversity of the area in the years to come. This is because, with the exception of the production along the Olifants and Berg Rivers, almost all irrigation depends on groundwater as a source of water, and less will be available in time to come. While the underground water reserve volume remains unknown at present, there is evidence of over-abstraction and reduced water quality in some aquifers. 76 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 In addition, a number of important biodiversity features are found within the area. The core of the production area coincides with an important ecological corridor, the Greater Cederberg Biodiversity Corridor, linking the conservation areas (including two World Heritage Sites) with the lowlands and the coast. The Verlorenvlei inland of Elands Bay is a World Heritage Wetland under a RAMSAR treaty. The vegetation of this area has been identified as a international biodiversity hotspot thus an area of global biodiversity significance, at least 65 rare and threatened plant species, 30 of which are unique to this region, and a large number of threatened animal species occur in the Sandveld. Three entire vegetation types (ecosystems) are restricted to this area, and all three are regarded as nationally threatened. Recent studies suggest that a further four new vegetation types should be recognised in this area, all of which are threatened. The sustainability of the agricultural system is dependent on the wise use of natural resources. One of the legs of sustainability is the environment, and in the production area on the West Coast it is being impacted in two key ways. Firstly the clearing of these threatened habitats for agricultural production and the abstraction of the water resource on which the business and many internationally important water dependent ecosystems depend. Potatoes South Africa and CapeNature have joined forces to address these challenges to agricultural sustainability through an initiative that has been named the Biodiversity Best Practices for Potato Production in the Sandveld. The projects key objectives are aimed at the: 3 Improvement of general farming practice through the implementation of the biodiversity best practice guidelines including the conservation of Critical Biodiversity Areas; 3 3 To improve soil conservation through the implementation of sound soil management principles; To improve water conservation through the implementation of efficient irrigation guidelines; 3 To improve soil fertility and plant nutrition through the implementation of effective fertilisation guidelines; 3 To promote integrated pest management and biological farming principles aimed at minimising the environmental impacts of agrochemicals. Progress with the Potatoes South Africa Best Practices Project have been: 3 3 77 There are currently 30 producers that have joined the project; The project area spans 86 000 ha of which 42 500 is still natural veld, 86% of this natural vegetation is threatened. Large BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 areas are identified as CBA's (CAPE FSP). This illustrates the ability of a project such as this to influence landuse practice at a landscape scale; 3 Nearly 10 000 hectares formally conserved through biodiversity agreements & contract nature reserves in the Sandveld with more than 2000 hectares located within the Bergrivier Municipal area. 6.6 STAKEHOLDER PARTICIPATION AND COMMUNICATION Forums and committees are establish to get stakeholder buy in, participation and active involvement from project conceptualising, planning and implementation. This is always a good platform to share common goals and inform the role players of progress and to create awareness levels. 6.6.1 GCBC STEERING COMMITTEE The objective of the GCBC Steering Committee is to oversee, advise and facilitate the implementation of the Greater Cederberg Biodiversity Corridor. This multi-sectoral steering committee (representation from 22 organizations) ensures meaningful participation and active involvement. The GCBC Steering Committee accepts that several other stakeholders are involved in the management of or have interest in the extended area and recognize the different mandates of its members. It act in support of and endeavour not to undermine these mandates. The Steering Committee is currently establishing working groups to deal with specific topics and issues. This will improve coordination between different role-players and institutions during the planning, budgeting and implementation phases of projects and programmes. Implication for the BRM The BRM should be an active member of all of these Committees and Coalitions as they all contribute directly to the conservation and management of biodiversity within the BRM. 6.6.2 SANDVELD INFO FORUM The forum was established with the goal to consolidate and encourage partnerships between Governmental departments, authorities, conservation agencies, NGO's, agricultural industries, research and landowners (Ranger et al 2006). Successes of this initiative: 78 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 The Sandveld Action Plan was drafted in 2006, on request by the MEC of the Department of Environmental Affairs and Development Planning and make recommendations to stakeholders on how to improve governance and natural resource management in the Sandveld. Although some of the recommendations were implemented, other are not sufficiently dealt with. In the initial stages of this forum biodiversity issues were the key discussion point, but today it has created a culture of sustainable natural resource utilization, management and protection of the Sandveld. 6.6.3 GROOT WINTERHOEK FRESHWATER STEWARDSHIP STEERING COMMITTEE This committee give guidance and inputs for the implementation of the Groot Winterhoek Freshwater Stewardship Core Corridor and consists of WWF-TMF (funders), Citrusdal Water Users Association, Department of Water Affairs, members of the Groot Winterhoek Conservancy, Landcare, CapeNature and the landowners. 6.6.4 GROOT WINTERHOEK PROTECTED AREA ADVISORY COMMITTEE The Groot Winterhoek Protected Areas Advisory Committee (PAAC) is intended to establish partnerships between the communities that live adjacent to protected areas and CapeNature's management staff. As envisaged in section 2(e) and (f) of the National Environmental Management: Protected Areas Act, 2003 (Act No 57 of 2003), the PAAC will play a crucial role in facilitating a participatory form of monitoring and management planning that reflects the needs and concerns of the communities. CapeNature has already established the Groot Winterhoek Protective Area Advisory Committee and the BRM must participate in order to establish links with CapeNature. This will strengthen local Community Based Natural Resource Management (CBNRM) and Local Economic Development (LED) initiatives. 6.6.5 VERLORENVLEI COALITION The recently withdrawn application for mining rights and newly submitted application for prospecting rights in the Moutonshoek Valley for tungsten ore are a huge concern and threat to not only Moutonshoek but also to the people who live in the district, their way of life, food security, provision of water, air quality and the potential for massive environmental degradation throughout the Verloren Valley from Piketberg to the Atlantic Ocean. To date 1400 individual members and 46 organisations have registered with the Verlorenvlei Coalition. 6.6.6 BERG RIVER ESTUARY MANAGEMENT FORUM This Committee was formed between the DWA, DEA&DP, West Coast District Municipality, BRM, Bergrivier Conservancy, Marine and Coastal Management, CapeNature and Civil Society. The committee meets to discuss management issues and concerns related to the Bergrivier Estuary. The management committee is in the process of determining the most appropriate institutional home for the management of 79 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 the Berg River Estuary and to provide a forum for stakeholders to report back on management activities. 6.6.7 VERLORENVLEI FORUM ESTUARY MANAGEMENT This forum is responsible for the implementation of the Verlorenvlei Estuary Management Plan (CSIR 2010) and to link the plan with other initiatives such as the Integrated Development Plan (IDP). The forum will appoint a chairperson and technical working groups that will be responsible for implementation. Technical working groups will consist of teams dealing with agriculture, enforcement, conservation, water quantity and quality, enterprise and entrepreneurial and empowerment. The BRM should engage with this forum. 6.7 LAW ENFORCEMENT TABLE 11: RESPONSIBILITIES OF VARIOUS DEPARTMENTS & INSTITUTIONS Type of activities Responsible Department Developments (agricultural, resorts, roads and Department of Environmental Affairs and other) Development Planning Overgrazing, erosion, alien subdivision of agriculture land plants, National Department of Agriculture Harvesting of protected plants, sell and buy protected plants, transport of game and plants, hunting, animals in captivity, CapeNature relocation of game, damage causing wildlife, indigenous fish 4 80 Water related issues Department of Water Affairs Activities related to the use of seashore and estuaries resources Marine and Coastal Management Rock art, changing the structure of buildings older than 50 years, paleontological assets South Africa Heritage Resource Agency BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 6.8 MONITORING BERGRIVIER BASELINE MONITORING PROGRAMME (BRBMP) The overall objectives of the BRBMP are to: 3 describe the natural and present state, including the natural variability, of those chemical, physical and biological characteristics of the river; 3 describe its hydraulically linked systems (i.e. estuary, floodplains and groundwater) that are most likely to be affected by changes imposed after the construction of the Bergriver Dam. 6.9 RESEARCH The final BRBMP report consists of five volumes. Volume 1 provides an introduction to the Bergrivier catchment and the groundwater environment, and an analysis of the natural and present-day flow regime. Volume 2 focuses on the riverine environment, Volume 3 on the Bergrivier estuary and floodplain and Volume 4 on social and cultural dependence on the Bergrivier and estuary. Volume 5 provides a synthesis of findings and recommendations for ongoing monitoring (Clark & Ractcliffe 2007). 81 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 COMMUNICATION 7. COMMUNICATION, EDUCATION AND PUBLIC AWARENESS The BRM has a communications policy that aims to adhere to the key constitutional tenets of transparency and public participation in the administration of this local authority. The communications policy must address the key challenge of communicating with stakeholders in a manner that allows free access to information that is presented in a way that is clearly understandable and in the language of choice. Fundamentally communication needs to be in the language that is understood by the target audience. Two target audiences are addressed in the policy and include: 3 3 The internal audience within the BRM the Executive Mayor, Mayoral Committee, Council Members, Senior and middle management and the staff; The external audience of the BRM Political Parties, Business Sector, NGO's, Religious denominations, media, civil society, other municipalities and government departments. The policy provides for effective communication between the Speaker who chairs the Council and the Executive Mayor and the Mayoral Committee with the Municipal Manager. In turn these two structures, Council & Mayoral Committee, within the municipality are the links and the eyes and ears of the municipality with the community at large. They are the channel through which information can be communicated to civil society and from which the needs, concerns and perceptions of the constituents can be heard within the municipal structure. The BRM has formalised the manner in which a motion is tabled with either the Council or the Mayoral Committee and handled in accordance with the various clauses and order rules of the BRM. The same holds true for Council members who request access to reports, enquiries and access to information. The municipal manager is legally responsible for communication between the municipality and political parties and office bearers. The manager’s office is the critical and only recognised link in this communications channel. All communication, both internal and external, speaking on behalf of the municipality must be undersigned by the municipal manager. There are a number of internal communication channels that have been created through which communication can funneled. These include staff meetings, management meetings, staff and management meetings, departmental meetings, committees, workshops and capacity building sessions, through a quarterly bulletin released by the municipality and via postings on the notice boards. Communications tools used by the BRM include the circulation of letters, e-mail, fax, telephone and the internet. Controls on communication are in place through formalised mechanism to discipline transgressions and allow aggrieved staff to raise objections. External communication occurs through the release of a municipal newsletter each quarter, the annual report of the BRM, the updating of the website, the supply of corporate materials through the office of the Strategic Manager, advertising and marketing through administrative services of the various departments and community meetings. In general all meetings convened by the municipality are open to the public other than in cases where the meetings have relevant grounds to be convened behind closed doors. The public however has the legal right to interact and influence the decision making process of the municipality through either written or oral representations in meetings or through the channels mentioned above. They also have the legal right to insist on a response or to gain access to information in the possession of the municipality. 82 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 Public participation is ensured through the Integrated Development Programme (IDP) which is prepared in September. A process plan for the IDP is prepared on approval of the IDP by the Council. Thereafter a budget is prepared and approved by Council. The communications strategy aims to ensure both horizontal and vertical communication within the structures of the municipality is achieved to provide for a healthy relationship with the public both internally and externally. 83 BIODIVERSITY REPORT | BERGRIVIER MUNICIPALITY | 2010 REFERENCES Anchor Environmental, 2008.
