7. Wild Futures Lecture outline: Lecture 7 Re-wilding Re-introductions of native species Workshop: Developing a wilderness inventory for Britain GEOG3320 – Management of Wilderness Environments 1 "Ability to see the cultural value of wilderness boils down, in the last analysis, to a question of intellectual humility. The shallowminded modern who has lost his footage in the land assumes that he has already discovered what is important...." Aldo Leopold, A Sand County Almanac Lecture 7 GEOG3320 – Management of Wilderness Environments 2 1. Re-wilding Emerging wild land policy in the UK - background of historical, environmental, social, political and economic drivers Benchmark projects Multiple benefits and environmental resilience - The Carrifran Wildwood Project - Trees for Life - Wild Ennerdale - Hafod y Llan - Wicken Fen Lecture 7 GEOG3320 – Management of Wilderness Environments 3 Question: What is re-wilding? Lecture 7 GEOG3320 – Management of Wilderness Environments 4 1. Re-wilding (cont’d) Multiple viewpoints as to what is ‘wild’ History of attrition Emerging policy Opportunities for (re)wilding Lecture 7 - from prehistory to present - recent revival in interest in ‘wild nature’ - Scotland (SNH, NTS, JMT) - England (English Nature, Wildlife Trusts) - Wales (Coed Eryri, CCW) - economic climate - policy climate - public interest GEOG3320 – Management of Wilderness Environments 5 1. Re-wilding (cont’d) Two basic approaches: - "letting go“ • if a landscape is left unmanaged for a long enough period, nature will take over and produce its own entirely natural landscape • may not necessarily be the same landscape that existed before human settlement, but it will be natural - "wild by design“ • we may need to actively 'design' wild landscapes by assisting the regeneration of native species to recreate a more natural looking landscape • limited economic activity in the form of low intensity grazing and recreation is still possible and indeed desirable • E.g. Council for National Parks (1998) Lecture 7 GEOG3320 – Management of Wilderness Environments 6 1. Re-wilding (cont’d) Developing new wild lands where opportunities arise - Edwards Review (1991) - CNP “Wild By Design” (1998) Aspects of re-wilding - promotion of wilderness qualities - enhancing and recreating semi-natural habitats - promotion of ecological process in near-natural areas Lecture 7 GEOG3320 – Management of Wilderness Environments 7 1. Re-wilding (cont’d) Lecture 7 Edwards Review (1991) “a number of experimental schemes on a limited scale should be set up in National Parks where farming is withdrawn entirely and the natural succession of vegetation is allowed to take its course” (Recommendation 6.3, Edwards, 1991) GEOG3320 – Management of Wilderness Environments 8 “Wild By Design” Lecture 7 Semi-natural areas, which appear natural but are in fact influenced by management for agriculture or forestry. Near-natural areas, where the land is totally divorced from agricultural or forestry use – in which natural processes are encouraged to maintain the diversity of habitats, and vegetation is free to vary naturally with variations in the physical environment. (After CNP, 1998, p.3) GEOG3320 – Management of Wilderness Environments 9 1. Re-wilding (cont’d) Promotion of the wilderness qualities - while maintaining productive use which may best be applied to semi-natural areas - in accordance with the aims of the UK Biodiversity Action Plan (BAP) to conserve and enhance biological diversity Lecture 7 GEOG3320 – Management of Wilderness Environments 10 1. Re-wilding (cont’d) Enhancing and recreating semi-natural habitats and recreating others For example: - reducing grazing pressure to allow vegetation to - Lecture 7 develop more naturally enhancing and restoring natural features such as river restoration schemes restructuring specific landscape elements such as conifer plantations to give a more natural outline GEOG3320 – Management of Wilderness Environments 11 1. Re-wilding (cont’d) Promotion of areas where ecological processes can be paramount - especially in near-natural areas where relatively large areas of land can be left without management for long periods of time Lecture 7 GEOG3320 – Management of Wilderness Environments 12 Question: What is the current basis for re-wilding in Britain? Lecture 7 GEOG3320 – Management of Wilderness Environments 13 1. Re-wilding (cont’d) Environmental resilience - how does (re)wilding fit with this approach/view? - drivers for change • social, environmental, economic - factors influencing environmental degradation and landscape response • robust nature vs delicate balance • landscape and public perceptions Lecture 7 GEOG3320 – Management of Wilderness Environments 14 1. Re-wilding (cont’d) Environmental drivers - climate change and ecological response • shifting patterns of migration and range • N-S movements and altitudinal shifts - changing geographies of nature - humanistic barriers to adaptability • lack of space/continuity between wild areas • pollution (critical loads) and environmental stress Lecture 7 GEOG3320 – Management of Wilderness Environments 15 1. Re-wilding (cont’d) Policy drivers - CAP reform and changes in agricultural subsidies paid to farmers • over-production/over-grazing • environmental stewardship • agri-environment schemes (fitting in) - habitat Directive • Natura 2000 • Biodiversity Action Plans (BAPs) • Water Framework Directive Lecture 7 GEOG3320 – Management of Wilderness Environments 16 1. Re-wilding (cont’d) Economic drivers - CAP reform and the single farm payment - agricultural ‘disasters’ • FMD • BSE - falling prices and the power of the big - Lecture 7 supermarkets increasing proportion of rural economy based on tourism and recreation GEOG3320 – Management of Wilderness Environments 17 1. Re-wilding (cont’d) Social drivers - rise in outdoor recreation and leisure time - greater mobility and disposable income - rural migration: • in migration of retirees and commuters • out migration of farm workers, etc. Lecture 7 GEOG3320 – Management of Wilderness Environments 18 1. Re-wilding (cont’d) Wilder Futures? Where do we go from here? Possible scenarios? Lecture 7 - change is inevitable… work with it - inclusive debate and decision-making - plan, respond and initiate - status quo - abandonment - rewilding - diversification - urbanisation GEOG3320 – Management of Wilderness Environments 19 1. Re-wilding (cont’d) Various strategic projects: The Wildland Network - LUPG’s “New Wildwoods Project” - RSPB’s “Futurescapes” - new umbrella organisation - objectives: • To promote the recognition and appreciation of wild land • To protect and conserve the qualities of wildness • To promote the establishment of complete ecosystems on a large scale, through research, advice, encouragement and education - http://www.wildland-network.org.uk/ Lecture 7 GEOG3320 – Management of Wilderness Environments 20 1. Re-wilding (cont’d) The next steps? - “Wild by Design” highlights the challenge…“the commitment to leave minimal intervention areas on a much larger scale (landscapes of thousands of hectares) and over much longer periods (hundreds of years)” (CNP, 1998) - integrating re-wilding with farming • “Wilderness and Plenty” Fraser Darling - packaging and marketing • selling idea to public and politicians - developing a workable and realistic strategy Lecture 7 GEOG3320 – Management of Wilderness Environments 21 2. Re-introductions of native species Nature management in UK? - maintaining habitats and species - remnants of former farming/forestry systems - management using past practice - i.e. “nature gardening” Lecture 7 Alternative systems? - less human intervention - role of large herbivores and predators? GEOG3320 – Management of Wilderness Environments 22 2. Re-introductions of native species (cont’d) Herbivores as a management tool? - NOT a unit of production (e.g. farm animals) - Vector of ecological maintenance • “shaggy gardeners” or “woolly mowers” • prevent tree regeneration on heaths • Maintain short grass sward on chalk down Lecture 7 GEOG3320 – Management of Wilderness Environments 23 Question: What are the key issues when considering use of large herbivores as a tool in rewilding projects? Lecture 7 GEOG3320 – Management of Wilderness Environments 24 2. Re-introductions of native species (cont’d) What are appropriate populations? - carrying capacity? - relationship between animal numbers and pattern and structure of vegetation? - species type? • grazers vs browsers vs foragers • preferred fodder • niche habitats (e.g. beaver in riparian zone) - predation and demographics? - The “herbivore guild” Lecture 7 GEOG3320 – Management of Wilderness Environments 25 Question: What is an appropriate “herbivore guild” for Britain? Lecture 7 GEOG3320 – Management of Wilderness Environments 26 Question: What about carnivores? Lecture 7 GEOG3320 – Management of Wilderness Environments 27 2. Re-introductions of native species (cont’d) US Wildlands Project: - “Cores, Corridors and Carnivores” - large mammalian carnivores seen as essential to wildland • bear • wolf • lynx - re-introductions in mainland Europe • bear and lynx (France, Spain, Switzerland, Austria, Itlay and Poland) • wolf (Norway, Germany, Poland and wider Alps) Lecture 7 GEOG3320 – Management of Wilderness Environments 28 2. Re-introductions of native species (cont’d) Lynx as a possible starting point - adaptable • variation in prey • range of suitable habitats (mountain scrub to dense forest) • cold adapted - mountains of Scotland, northern England, Wales • sufficient prey and habitat Lecture 7 GEOG3320 – Management of Wilderness Environments 29 Question: What about wolf and bear?
