GOWY MEADOWS RESERVE Site Management Plan 2010-2020 (with a 25-year vision) STAGE 1 - DESCRIPTION Chapter 1.1 General information 1.1.1 Location The reserve sits on the eastern flank of the River Gowy, immediately to the south of Stanlow Oil Refinery on the southern side of the Mersey Estuary, about 3 km southeast of Ellesmere Port and 8 km northeast of Chester. 1.1.2 Summary description Gowy Meadows Nature Reserve covers 166 ha on the eastern bank of the Gowy floodplain, close to the river’s confluence with the River Mersey at Stanlow. Two-thirds of the site comprises rushy pasture on the flood plain itself, with the remaining third, along the eastern side, being on drier mineral ground. A network of straight open ditches drains the peaty soils of the former tidal marshes. They support a diverse flora and fauna, which includes several species classed as rare or uncommon in Cheshire, currently making them one of the site’s most important wildlife features. The fields on the mineral soil have been improved to a greater extent agriculturally, but old hedges and boundary trees still enclose them and the old green lanes that give access to the reserve. The Reserve is held on a 25-year lease from the owners, Shell UK. Assisted by a Countryside Stewardship agreement to maintain the infrastructure and habitat features, CWT’s stock graze the majority of the land, while the southeastern third is sublet to a local grazier. Shooting rights are retained by the landowners and let to Newton-le-Willows Wildfowlers. 1.1.3 Land tenure The entire reserve is leased from Shell UK. The agreement to manage the land for nature conservation was agreed on 1st May 2000 and runs for 25 years until 30th April 2025. The majority is grazed by CWT, but an area of approximately 45 ha is sub-let to local farmers under an annual grazing licence agreement. 1 1.1.4 Map coverage Ordnance Survey has produced many editions of their maps since the mid 19th Century, most available at 1:2500 (or 25 inches:1 mile) scale, providing an invaluable record of floodplain development. One early example from the 1870s, predating the Manchester Ship canal and Stanlow refinery, is presented as Map A: other prints are stored in ‘Gail’s White File’. The current relevant Ordnance Survey coverage is: 1:50,000 ‘Landranger’ Series - Sheet 117, ‘Chester’; 1:25,000 ‘Pathfinder’ Series - Sheet SJ47; 1:25,000 ‘Explorer’ Series - Sheets 266 & 267; 1:10,000 Sheet SJ47SW; 1km MasterMap tiles SJ4373, SJ4473, SJ4374, SJ4473. [OS 1:10,000 raster data, held digitally by Cheshire Wildlife Trust, has been used as the base on which to present the maps created for this management plan.] 1.1.5 Photographic coverage 1.1.5.1 Ground-based Many photographs have been taken to record aspects of the site over the last 20 years: Natural England may still hold photographs taken during pSSSI appraisal (late 1980s). ‘Gail’s White File’ holds contact prints of photograph collections held on CWT computer files and on CD Paul Hill - ‘Photographic Monitoring’ October 1999 (digital files? fixed point?) Most of the survey reports contain general views and topic-specific photographs. Several photographs were taken to record the condition of the Reserve at the beginning of the Plan period. These are included in Appendix 2 and are referenced within the Plan text [numbers in square brackets] with their position shown on Map L, also in Appendix 2. 1.1.5.2 Aerial Air photograph material is available (prints in Gail’s White File) from the following years: 17th July 1972 (black & white) 6th June 1993 (colour) ‘May 2003’ (colour) ‘Google Earth’ provides colour satellite imagery dated: 5th March 2003 23rd November 2003 27th April 2005 (a print is reproduced as Map B) 2 Chapter 1.2 Environmental information 1.2.1 Physical 1.2.1.1 Climate No unusual climatic factors affect the site, although its open character leaves it exposed to winds from all directions. Annual average precipitation recorded at Liverpool Airport on the other side of the estuary is 775 mm/year. 1.2.1.2 Hydrology The canalised River Gowy drains the floodplain centrally towards the north, with the agricultural land to the east and west served by a network of drainage ditches. The reserve itself is served by two ‘main river’ open ditches - Thornton Main Drain (TMD) running S-N across the centre of the floodplain land and Thornton Uplands along its eastern flank - both these ditches arise to the south of the M56. TMD is unusual in that it passes through a siphon under Thornton Brook towards the north of the reserve. The latter is a W-E channel, which was engineered to carry the main flow of the River Gowy during the 19th-century, but is now cut-off by a floodgate. Thornton Uplands enters this still-water channel, giving Thornton Brook a flow beyond the confluence. In 2003 Thornton Brook was diverted along a new channel excavated across the northern edge of the reserve, which now outfalls to the Gowy of the reserve’s northwestern corner. A boarded sluice, set at 4.25 m AOD, controls the outfall from TMD into the new channel. All these watercourses are shown on Map C. 1.2.1.3 Geology Sandstone rocks of Triassic origin provide the underlying hard geology. The ‘Chester Pebble Beds Formation (CPB)’ underlies the southwestern half of the Reserve, corresponding to those parts where superficial deposits are either ‘Peat’ or ‘Wind-blown Sand’. The ‘Wilmslow Sandstone Formation (WLSF)’ underlies the northeastern half of the Reserve, corresponding to those parts where superficial deposits are either ‘Tidal Flat’ or ‘Devensian Till’. A geological fault approximately follows the line of Thornton Green Lane, with the Chester Pebble Beds underlying further to the northeast. These pebble beds outcrop in Thornton-le-Moors village. See Map D. 1.2.1.4 Geomorphology Prior to construction of the Manchester Ship Canal and Stanlow Refinery the northernmost reaches of the River Gowy were tidal and much of the reserve area would have been saltmarsh, with brackish creeks. Today, the floodplain is flat with the shallow channels of the former creeks evident locally. On the eastern flank of the Reserve the mineral ground rises by about 5 m to the 10 m contour. 3 1.2.1.5 Soils [To be completed - see Soils report in SBI file]. The dry fields adjacent to the M56 were used to receive overburden during the motorway’s construction. 1.2.2 Biological 1.2.2.1 Flora The long history of moderately intensive agricultural use, with fertilizer and herbicide applications, has left virtually all grassland areas comparatively species-poor. The drier, mineral soils support semi-improved neutral grassland, NVC MG7, while the peaty floodplain is more acidic, but again species-poor and widely dominated by Soft Rush Juncus effusus and Tufted Hair-grass Deschampsia caespitosa in a mosaic comprising NVC MG9, MG10, MG13, M23 and M27. One small clump of Meadow Rue Thalictrum flavum towards the southwest [photo 3] and patches of Brown Sedge Carex disticha towards the northwest [photo 4] are the only uncommon species to be found in the floodplain grassland. Two areas in particular retain standing, open water through a good part of most years [photos 9 & 10]. In sharp contrast, the main ditches are moderately species-rich locally, particularly TMD, where Water Violet Hottonia palustris and Bladderwort Utricularia australis were found quite widely until very recently. Whorl-grass Catabrosa aquatica, also locally uncommon, appears to be increasing, especially in the dead-arm section of Thornton Brook. Common Reed Phragmites australis dominates a few ditches, especially towards the north end. NVC swamp and aquatic communities represented include primarily: NVC A2b, A9b, S4 and S14. Five mature Black Poplar Populus nigra ssp. betulifolia survive as hedgerow trees on the drier grassland [one is shown in the plan cover photo]. Features of botanical interest (and the locations of invasive ‘weeds’) are shown on Map E. 1.2.2.2 Fauna The ditch network is also the focus for most of the faunal interest on the Reserve, with aquatic invertebrates being particularly well represented, notably including Mud Snail Omphiscola glabra and Lesser Silver Water Beetle Hydrochara caraboides. Water Voles Arvicola amphibius breed along several of the permanent water ditches. Otters Lutra lutra are known to move along the River Gowy and Great Crested Newt Triturus cristatus populations breed in about half the field ponds [though not the one in photo 12]. Bird usage is surprisingly limited: Snipe Gallinago gallinago breed very occasionally and one or two pairs of Lapwing Vanellus vanellus. Unusually large numbers of Stonechat Saxicola torquata breed in the isolated Hawthorn bushes along the ditch lines. Features of faunal interest are shown on Map F. 4 1.2.2.3 Communities Undoubtedly the ditches support the most significant flora and fauna communities, with the greatest diversity to be found along the deeper, more open sections of the watercourses. 1.2.3 Cultural 1.2.3.1 Archaeology No particular interest has been identified. 1.2.3.2 Landuse Longhorn cattle graze the majority of the site [photo 1], including most of the floodplain and northern parts of the mineral land. Hebridean sheep graze much of the rest, while the tenanted land might support various breeds of agricultural livestock. Several fields are closed to grazing in spring with a hay crop taken, followed by aftermath grazing. The northwest sector of the floodplain is currently ungrazed because there is no waters supply for grazing animals - a temporary situation while Shell repair pipes from their water abstraction points (pumping stations are scattered across the holding). The public footpath crossing the site gives local residents access to the site for passive recreation. The northern edge of the site is a corridor for buried water, gas and electrical services and three substantial overhead power lines cross the northern half of the Reserve. 1.2.3.3 Past management for nature conservation Management primarily for nature conservation has only occurred since CWT took over the lease for the land. Prior to this, four graziers tenanted the land with no LSV constraints and included the grazing of horses and the cutting of hay. A Countryside Stewardship agreement (1st Oct 2001 to 30th Sept 2011) has prescribed much of the recent management, the details of which include: [Compile summary list from the Agreement] Although several plans have been drawn up to more actively enhance the reserve’s wetlands, the sluice at the outfall of TMD has been the only major infrastructure modification. Environment Agency/CWT undertake annual cutting/de-weeding along the River Gowy and ‘main river’ ditches, an activity considered essential to flood defence, but also judged to be of benefit for nature conservation because it maintains open conditions. 5 1.2.3.4 Public interest Although acquisition generated much interest amongst Trust members and local naturalists, the reserve hasn't yet been promoted to the wider public and the site retains a fairly low profile. Promotion and interest might have been greater if public access were easier [photo 13]. One public footpath, running E-W across the northern half of reserve is currently the only access and the terms of the lease do not permit the development of a visitor centre or allow large groups of people to be guided round the reserve (Health and Safety Regulations do not allow ‘gatherings’ of more than five people within 2 km of Shell’s petrol refinery). 6 1.2.4 Ecological relationships and implications for management Two major historical changes have reshaped the ‘natural’ ecological relationships on the Reserve: Exclusion of tidal waters and major industrial development of the land between the Reserve and the estuary has resulted in this area of floodplain no longer being a selfsustaining estuarine creek. River engineering and land drainage to facilitate agricultural use and industrial facilities on the ‘reclaimed’ land mean that the whole area remains much drier than it might be naturally. If the ground were left unmanaged, it would certainly not return to the condition it was in 200 years ago. Allowing ecological processes to follow their natural course (total, nonintervention management) is not an option, because strategically important drainage channels through the site will be rigorously maintained by others, in order to preserve developments up and downstream of the reserve. The current drier and freshwater (non-saline) environment has to be accepted as the prevailing baseline condition against which to envisage the succession that might occur and how management might be needed to limit or control these changes. Non-intervention (apart from essential drain maintenance) would probably result in a gradual succession to Willow carr over rank grassland, with Hawthorn and Ash colonising the drier mineral ground to the east. Additionally, it must be appreciated that current management activities (enforced and preferred) are maintaining the primary features of interest on the site. Key flora and fauna features of the site are only able to survive because of intervention management; because they require open conditions [photo 2]. Long-standing aspirations to return the site to the important wildfowl and wader refuge that it used to be could only be realised if open conditions are maintained. The clear implication is that continued, moderately intensive management activity to prevent succession to woody shrubs and trees will be essential to maintaining current interest and to realising potential. 7 Chapter 1.3 Bibliography Site Management Plans for Nature Conservation, Nature Conservancy Council, 1988 (used as the template for this plan).

At that time, the true importance the rare and diverse aquatic invertebrate fauna was awaiting discovery. 2.1.2 SSSI status under Wildlife and Countryside Act 1981 The site currently has no national designation. Since SSSI consideration in the early 1990s, the aquatic invertebrate fauna diversity (an assemblage, including several national rarities) has been identified and appears to qualify the site for SSSI designation. Natural England is not currently considering notification. 2.1.3 cSAC status under EC ‘Habitat & Species Directive’ The site has no European designation. 2.1.4 Site definition and boundaries The lease agreement defines the Reserve boundaries, which are very obvious on the ground because they follow strong physical features on all sides: North edge - Oil Sites Road, A5117 (highway boundary) East edge Thornton Green Lane (west roadside hedge) South edge - M56 motorway (highway boundary) West edge - River Gowy (mid-line of the canalised channel) The only deviation is around the village of Thornton-le-Moors, where residential properties, a small recreational woodland park and a single field adjacent to the village are all excluded. (See Map G and all others) 9 Chapter 2.2 Evaluation of features 2.2.1 Evaluation 2.2.1.1 Size At 166 ha, the Reserve is the largest area of land managed by CWT and is undoubtedly a significant area of floodplain. The land holding is considered large enough to encompass the full range of habitats - from the river itself, to the fringing mineral ground - and moderately resilient to outside influences. E-W highway links (M56 and A56) and development of the Gowy Landfill facility have fragmented the lower Gowy floodplain, which extends southwards, flat and wide, as far as Hockenhull Platts Reserve, almost 10 km upstream. 2.2.1.2 Diversity Habitat diversity is generally high, particularly the range from open water, through aquatic and emergent vegetation to marshy grassland types, with high botanical and aquatic invertebrate diversity in some ditches and marshy areas. However, it should also be noted that the botanical diversity of both dry and marshy grassland is poor, except in one or two compartments at the northern end of the Reserve. 2.2.1.3 Naturalness The majority of the site has been severely modified by tidal exclusion, land drainage and previously more intensive agricultural use. The most natural communities are now to be found in watercourses all created or modified by man - the River Gowy’s canalised channel and the network of ditches. Grassland areas are the least natural, although some compartments towards the northern end appear to have been less improved by ploughing, fertiliser and herbicide applications or the effects of sustained intensive grazing than the majority. Patches of invasive alien plants scattered across the site detract from its naturalness. 2.2.1.4 Rarity Agricultural intensification has undoubtedly been greater on other parts of the floodplain (e.g. the western flank of the river) and the reserve remains a rare example of such an extensive area of floodplain grassland that hasn’t been completely ‘improved’. Consequently, the Reserve also still supports several plants and animals that are classed as ‘rare’ or ‘declining’. 2.2.1.5 Fragility The site’s large size makes it reasonably robust to withstand external influences e.g. spray drift. At the other extreme, the pristine conditions of ditches and their flora and fauna, are very sensitive to change. TMD in particular is extremely susceptible to any change in either the quality or quantity of water entering the system from upstream, outside the Reserve. 10 2.2.1.6 Typicalness Gowy Meadows is not typical of river floodplains found in Cheshire because of the deep peat underlying its grassland and former estuarine influences. In many ways, the communities on Gowy Reserve are more typical of those found on the Somerset Levels. 2.2.1.7 Recorded history Historical development of the field pattern, changes to the River and its outfall to the Mersey Estuary are all well recorded in the series of OS maps produced since the mid-19th century. Social and agricultural history is less well researched. 2.2.1.8 Position within the ecological unit Gowy Meadows Reserve sits strategically between the Dee Estuary (3 km to the west) and the Mersey Estuary (2 km to the north). Wildfowl and waders from either of these important sites are likely to use the Reserve as a refuge during periods of particularly harsh weather. Within the South Mersey Marshes, the Gowy floodplain sits at the western end of a broad tract of freshwater marshes, stretching from the River Weaver across Frodsham, Lordship and Ince Marshes. 2.2.1.9 Potential value Given the degree of drainage and agricultural improvement that has occurred across the site over the last 200 years, there is a great deal of potential for restoration. Indeed, some wet and dry grassland has been so improved that little of value would be lost if the land had to be heavily disturbed during habitat creation. Particularly, there appears to be potential for reedbed creation on part of the floodplain and opportunities for pond creation and to diversify the sward in hay meadows on the mineral ground [photo 16]. Habitat improvement could potentially attract more wildfowl and waders as well as ‘farmland birds’. 2.2.1.10 Intrinsic appeal Undoubtedly the marshes retain a considerable amount of their ‘wilderness’ appeal. Despite the intrusion of traffic on the M56 motorway and the industrial noise and pungent aromas from the refinery, standing in the middle of the reserve, these become merely features on the horizon. The site is not a particularly colourful place even in midsummer. Nevertheless, the diverse vegetation and clear water channel of the River Gowy has a particular appeal, possibly reaching a peak in early summer, when clouds of Banded Demoiselles emerge along its banks. Similar could be said of the clean ditches with their summer show of Water Violet. The emergence of red flowers and young foliage on the Black Poplars is a particularly noticeable spring feature. One small botanically richer compartment in the north becomes a blaze of purple in late summer when Knapweed and Marsh Thistle flower in abundance [photo 11]. 11 2.2.2 Identification/confirmation of important features From a nature conservation point of view, the restorable wet grassland and ditches, with their associated flora and fauna are the most important features (full details are set out in Table 1 below).

Its sheer extent and the type of grazing available give it great flexibility to hold additional stock periodically. Similarly, site quality wouldn’t deteriorate rapidly when under-grazed, should stock be required elsewhere. Conversely, although the site is very large, the cattle herds and sheep flocks managed by CWT should have sufficiently capacity to cope. With the range of animal types available, it should be possible to apply appropriate grazing pressures to break down the tussocky structure of the peaty grassland, at the same time sensitively browsing along ditch margins [photo 6]. Most importantly, lying at the heart of the Gowy and Mersey Marshes Living Landscape Project area, gives this CWT reserve added value as a demonstration site, to give an indication of what can be achieved in floodplain conservation and enhancement. 13 2.2.4 Specified limits Many key interest features could increase in extent or diversity indefinitely without causing concern, provided they don’t begin to adversely influence other key features. Negative features could disappear or invasive species could become extinct, again without concern. Significant or consistent declines in extent of key habitats and species or their population sizes or increases in invasive species (or habitat types) would be undesirable trends, but setting absolute limits is often difficult because of the natural variations in populations in response to weather and or predation. In some cases, no reliable baseline figure has been measured or agreed. Beyond these generalisations, Table 2 below gives some specific indications of when ‘ecological alarm bells’ should start to ring and suggests several parameters that it will be particularly important to monitor: Table 2. Guideline Table of Specified Limits Feature Range or Limit pH in upper TMD <6.5 at all times Ponds No less than 50% open water area (averaged across all ponds, midsummer). No more than 50% scrub/tree cover (av. across all ponds, midsummer). Burrows always occupied along parts of TMD, the core of the population. Water Vole Great Crested Newt No less than 3 ponds with established breeding. No less than 6, two years after the new ponds have been created. At least two pairs of breeding Lapwing, one pair of Snipe. Wildfowl & waders (esp. Shoveller, Lapwing, Snipe and Redshank*) Raptors (esp. Kestrel, Barn No reduction in existing occasional visits/usage. Owl, Hobby and Peregrine) Aquatic invertebrate No drop in Community Conservation Index value. (Presently calculated on assemblage difficult to replicate, M Tynen survey data: needs recalculation based on a series of sample sites.) Mud Snail Known sites permanently wet or dry for more than one year. No loss of known sites (shown by no snails detected in consecutive years). Lesser Silver Water Beetle No loss of known sites (shown by no cocoons or adults being detected in consecutive years). Black Poplar Sufficient successful take of new plantings to ensure there will be more than 5 trees in 100yrs. Bladderwort [Baseline required] Meadow Rue Existing stand conserved or replaced by fresh colonisation elsewhere Water-violet [Baseline required] Japanese Knotweed No increase. Gradual reduction in number and extent of stands Creeping Thistle/Ragwort No more than ‘occasional’ in any compartment. Himalayan Balsam No spread beyond the established stands along River Gowy margins. 14 2.2.5 Ideal management objectives The ‘Ideal Objectives’ (listed below) concentrate solely on wildlife considerations and are not constrained by the ‘real world’ situation. They provide a useful theoretical baseline when drawing up Operational Objectives (Chapter 2.4), which take into account the trends and constraints discussed in Chapter 2.3. To preserve/enhance the open character of the floodplain, creating conditions suitable for the long-term development of a vegetation mosaic typical of peaty, lowland grassland typified by the community types: MG9, MG10, MG13, M23 and M27 (as defined by the National Vegetation Classification (NVC) (Rodwell, 1991). To preserve, enhance and increase the ditches and seasonally flooded areas, especially Phragmites reedbed, associated with the floodplain grassland zone (NVC A2b, A9b, S4, S14, &c.) To preserve/enhance previously agriculturally improved dry neutral grassland, managing land by traditional grazing and/or haymaking to encourage the development of a more typical NVC MG5 (or MG4) community type. To safeguard, maintain and enhance appropriate habitat within those parts of the site that the following fauna species are already known to use: Otter, Water Vole, Stonechat, Reed Bunting, Reed Warbler, Great Crested Newt, Mud Snail, Lesser Silver Water Beetle and general aquatic invertebrate assemblage. To safeguard, maintain and enhance appropriate habitat within those parts of the site where the following plants are already found: Black Poplar, Bladderwort, Brown Sedge, Meadow Rue, Whorl-grass and Water-violet. To enhance wet and dry grassland to provide breeding/over-wintering habitat attractive to Lapwing and a variety of wildfowl and wading birds. To preserve, enhance and increase pond and hedgerow features associated with the dry grassland zone. To maintain conditions to support avian predators such as Barn Owl, Peregrine Falcon, and Hobby and enhance wetland grassland to bring additional characteristic raptors such as Short-eared Owl, Marsh Harrier and Hen Harrier. To prescribe and carry out an effective, low intensity monitoring strategy to enable the effectiveness of the management strategies to be assessed, and to provide useful data to assess unexpected habitat or species change attributable to off-site influences. To maintain an infrastructure allowing access for maintenance, monitoring and controlled public access across the site. To increase public awareness and appreciation of the wildlife value of habitats associated with lowland wet grassland and traditionally managed farmland. To improve wildlife links that connect Gowy Meadows Reserve to other wet grassland in the River Gowy floodplain and the nearby ‘Mersey’ Marshes. 15 Chapter 2.3 Factors influencing management 2.3.1 Natural trends Without management, grassland would become even more rank and invaded by Willow and Hawthorn depending on the wetness of the ground. Without clearance, ditches would become choked with vegetation, silt up and eventually flood onto fields or at least cease their drainage function. Trees and shrubs would gradually shade out the ponds and ditches. Neither trend is considered beneficial to nature conservation. In any case, succession will not be allowed to proceed in the ditches, to ensure there is no flooding of Gowy landfill upstream and industrial interests downstream. Invasive weeds such as Creeping Thistle, Ragwort, Water Fern and Himalayan Balsam have the competitive ability to increase significantly [photos 14 & 15]. 2.3.2 Man-induced trends Under current grazing pressure, the tussocky structure of wet grassland would be broken down. Ongoing ditch maintenance/management by EA and CWT will perpetuate their drainage function and maintain open conditions beneficial to flora and fauna diversity. 2.3.3 External factors Drainage from M56 could bring pollution from salt applications, accidents and spillages. Under rare conditions of a high tide and substantial surface run-off from the Gowy catchment, the river flood banks would over-top, flooding the reserve with river water. This flooding doesn’t appear to have caused damage to the site when it has occurred in the past – indeed the frequency of such flooding is something that this plan seeks to increase Surface water drainage from the landfill site upstream to the south, which currently feeds into TMD, has the potential to affect the sensitive water chemistry, flora and fauna in that ditch and its side arms, particularly while soils are being reworked over the dome. In the longterm, even after the tip has long been completed, CWT will remain obliged to maintain unimpeded flow along Thornton Main Drain to prevent water backing up and flooding the landfill cells, causing far more serious pollution. Fumes from Stanlow Refinery probably do no harm to features of interest, but do nothing to improve visitors’ enjoyment. 16 2.3.4 Obligations To observe no-dig zones, related to gas/electricity/sewerage installations To permit National Grid and their contractors access to pylons To permit access to Shell’s water abstraction infrastructure To permit Environment Agency maintenance staff access to the River Gowy flood-banks and ‘Main River’ sections to undertake annual works To maintain drainage function along TMD and other major water courses To adhere to the terms of the Countryside Stewardship agreement 2.3.5 Legal constraints 2.3.5.1 Constraints of tenure There are many in the terms of lease. Reference to the lease itself should be made for full details, but in summary these include: [To be completed from the lease] The lease is transferable to the new owners of the site should Shell decide to sell their interest. 2.3.5.2 Constraints of access Existing access routes for vehicles required for management work are shown on Map G, which also indicates the existing public footpaths. 2.3.5.3 Health and Safety All normal responsibilities apply. Additional constraints are contained within the lease agreement. Some of the marshes and many of the ponds, ditches and larger watercourses are very deep, often appearing shallow, but actually having floating rafts of vegetation and/or deep, soft sediments. 2.3.5.4 Wildlife Water Voles and their habitat are protected under the Wildlife and Countryside Act 1986, as amended. Any work to ditches and bank-sides that support Water Voles should be guided by a Method Statement agreed with Environment Agency. Great Crested Newt presence in several ponds (a species benefiting from European legal protection), requires a Pond Conservation Licence to cover positive management work to aquatic or terrestrial habitats and pond creation near to existing breeding sites. Management activity should also be mindful of the presence of Lesser Silver Water Beetle (also benefiting from European legal protection). There should be no disturbance of breeding sites and the egg cocoons produced in May, a particularly sensitive month to be avoided. No breeding birds should be disturbed, nor should any birds benefiting from ‘Special’ protection while they are present on the site, effectively pushing much management work on the open grassland and hedgerows into the late summer to early spring period. 17 2.3.6 Management and other key constraints The current distribution of legally protected species constrains, for example, water level raising projects or at least the timing/means of managing/enhancing. Potential cost and manpower requirements will be the primary concerns. However, these are not envisaged to be a serious constraint to a rotational and carefully phased maintenance programme. It is perceived that while management input is likely to need to remain fairly high in the short term, the demands will decrease as the capital works are completed and the site settles down to any modified water level or grazing regime conditions. Public opinion and support for management activities needs to be carefully considered at such a high profile site. Many activities carried out in the interests of nature conservation (such as ditching work or removal of problematic plants/animals) are likely to be seen as only destructive unless clearly and fully explained/justified to site visitors. The Trust might not hold sufficient stock of the right type to implement the desired grazing regimes [photo 6]. Having to maintain flows along TMD to prevent the landfill site flooding is a particularly onerous management constraint (severely limiting the scope for water level management). Rewetting will make pedestrian and vehicle access more difficult, requiring careful planning and possibly the provision of additional bridge infrastructure. 2.3.7 Impact assessment The overall thrust of the management effort is directed towards ‘nature conservation’ and most prescriptions are to be at a ‘limited intervention’ level. Therefore, implementation of the plan should not give rise to any significant adverse impacts. Quite the reverse, implementing the prescriptions is essential to maintaining and enhancing existing interests. However, badly timed management works could cause avoidable disturbance. Cessation of conservation and access management across the reserve would lead to a deterioration of its open habitats as succession advances. Other invasive colonisers (such as Japanese Knotweed, Himalayan Balsam and Water Fern) would extend their dominance at the expense of native flora and fauna. Communities occupying any areas where water levels have been raised will suffer short-term adverse impacts as they adjust to the wetter environment, but refuges for communities that require drier conditions from time to time will always remain around edges of the site. In summary, it appears that a sustainable balance of wildlife and human requirements can be accommodated on the Reserve. Furthermore, the management activity required to maintain wildlife resources appears to be sustainable, but only with some financial subsidy and volunteer input at present. 18 Chapter 2.4 Operational objectives and management options 2.4.1 Rationale Table 3 below shows how the constraints identified in Sections 2.3.1-6 limit the Ideal Objectives listed in Section 2.2.5. The resulting Operational Objectives and prescriptions shown in Table 4 are indicated in the right hand column. Table 3: Rationalisation of Ideal Management Objectives Ideal Objective (abbreviated) Constraint Preserve/enhance the open character of the floodplain, creating conditions suitable for the long-term development of a vegetation mosaic typical of peaty, lowland grassland. Preserve, enhance and increase the ditches and seasonally flooded areas, especially Phragmites reedbed, associated with the floodplain grassland zone. Preserve/enhance previously agriculturally improved dry neutral grassland, managing land by traditional grazing and/or haymaking to encourage the development of a more typical community type. Safeguard, maintain and enhance appropriate habitat within those parts of the site that key fauna species are already known to use. Safeguard, maintain and enhance appropriate habitat within those parts of the site where key plants are already found. Enhance wet and dry grassland to provide breeding/over-wintering habitat attractive to Lapwing and a variety of wildfowl and wading birds. Preserve, enhance and increase pond and hedgerow features associated with the dry grassland zone. Maintain conditions to support avian predators and enhance wetland grassland to bring additional characteristic raptors. Prescribe and carry out an effective, low intensity monitoring strategy to enable the effectiveness of the management strategies to be assessed, and to provide useful data to assess unexpected habitat or species change attributable to off-site influences. Maintain an infrastructure allowing access for maintenance, monitoring and controlled public access across the site Increase public awareness and appreciation of the wildlife value of habitats associated with lowland wet grassland and traditionally managed farmland Improve wildlife links that connect Gowy Meadows Reserve to other wet grassland in the River Gowy floodplain and the nearby ‘Mersey’ Marshes Operational Objective/prescription Water level control (TMD). Water for stock. Vehicle access for topping. As ‘Ideal’, but prescriptions need to accommodate constraints. Water level control. Safe poaching by stock. Potential pollution (TMD). Limited water quality data. Cost, if not funded. Legacy of elevated soil nutrient levels. As ‘Ideal’, but prescriptions need to accommodate constraints. Conflicting requirements of different species with overlapping distributions. Enhancement only when not adversely affecting other species of interest. Conflicting requirements of different species with overlapping distributions. Tussocky nature of sward. No tilled land. As for fauna (above), but there is less likelihood of conflict. Cost, if not funded. GCN presence, otherwise none. Adverse impact on Water Voles, Waterfowl and Waders. Cost, if not funded. Insufficient experts to undertake the work. As ‘Ideal’, but ensure a Pond Conservation Licence is in place. H & S (terms of lease). No infrastructure (styles, paths and bridges). Limited public access on site, otherwise none. Objective should be for only limited increase. Landfill site sterilises a part. Highway fragmentation. Stanlow refinery. CWT is not the landowner. Use opportunities arising from ‘Mersey and Gowy Washlands Project’. Offer grazing if stock available. 19 As ‘Ideal’, but land may require remedial soil nutrient stripping. Concentrate effort on areas where there will be least public disturbance. Enhance habitats to increase capacity. Very important, but constraints impose stringent limitations on scope. Essential to adopt a ‘SMART’ monitoring strategy. Use the site to promote sensitive floodplain management via ‘The Grebe’ and other media. 2.4.2 Identification of operational objectives and selection of management options and outline prescriptions Please refer to Table 4 (pages 21 & 22), which follows overleaf.

Within each category there are several options: A Habitat management A1 Non-intervention - natural response to be allowed to develop, accepting subsequent development. A2 Limited intervention - natural response to be allowed to develop, accepting subsequent development, subject to specific conditions or limits. A3 Active management - create and/or maintain a defined habitat. B Species management B1 Non-intervention - no management action is required. B2 Control and reduction - management action needed to maintain or limit individual populations. B3 Encouragement and increase - action required to increase numbers of a species or group of species. B4 Re-introduction - re-introduction of a formerly occurring species. B5 Introduction - establishment of a species not known to have occurred there formerly. 23 C Study and research Most sites are suitable for some degree of study or research. Different options may apply to different areas of complex or fragile sites. Facilities that can be provided include the research provision of permits for work and help with research. C1 No facilities - site unsuited to study - usually fragile or dangerous sites. C2 Specialist facilities - provision only when study/research will benefit the management of the site. C3 Controlled facilities - for use by small numbers, when or where thought acceptable. C4 Open facilities - any request to carry out study/research will be granted or encouraged. D Education and interpretation Educational groups often use sites. The level of provision of interpretative material varies with the suitability of that site, or parts of that site, to withstand visitor pressure. D1 Minimum publicity - not for educational use. Typically a fragile/unsafe site. D2 Low-key publicity - no active encouragement of educational use, no provision of interpretative material. D3 Active publicity - site to be used for education. Locally publicised. Interpretative materials such as booklets or displays to accompany nature trails. D4 Special promotion - high profile site, with board displays, trails, educational packs, visitor centre. Habitat management for demonstration purposes. E General access and recreation Access will often have to be controlled to aid management, but Rights of Way and established use must be respected. E1 Closed - no access. Not possible where Rights of Way exist. E2 Restricted access - access for permit holders only or on Rights of Way. Used to control sensitive areas or sites. E3 Partially open access - permit required away from Rights of Way. E4 Open access - no access permission required, but some restriction may be imposed through byelaws. 24 STAGE 3 - PRESCRIPTIONS Chapter 3.1 Projects 3.1.1 Project register and description Specific ‘projects’ should be developed from the prescriptions listed in Table 4. Chapter 3.2 Work schedule 3.2.1/2 Work programme/Annual Work Plan This could be developed in outline for the 10 years of the plan period and in more detail for each year, from projects arising from the final columns in Table 4, by the Reserve staff who understand the constraints on (and opportunities presented by) the best use of available time, manpower and mechanical skills. The anticipated Higher Level Stewardship application and agreement is likely to have a significant influence on the work programme over the next 10 years. Chapter 3.3 Control 3.3.3 Plan review There are several references in Table 4 to aspects of the site requiring survey or monitoring work. A well-devised monitoring strategy will target survey effort so it will be very importance to consider any trends indicated by that work when critically reviewing the successes and failures of management activity during the preceding plan period. When updating the plan for the next 10-year period, the prescriptions may need to be adjusted if management is not achieving the desired objectives. In some cases, although the trend may be in the right direction, the desired state may not be being achieved quickly enough, indicating that the management regime should be modified. Unexpected ‘side-effects’ of management should be identified to ensure that beneficial effects outweigh any undesirable trends. The sustainability of management work should also be assessed; a carefully prepared plan review will be very helpful when attempting to secure funding or manpower to implement the next 10-year phase. Conversely, if existing funding cannot be sustained or other constraints become evident, then management priorities can be reassessed more easily. In the hope of maintaining a longer-term perspective, a vision for the Reserve 25 years on is presented in Stage 4 overleaf. 25 STAGE 4 - LONGER-TERM VISION - 25 YEARS ON The landfill site has been completed and has a modified drainage system, which involves a local relief solution to permit overflows from the upper end of TMD direct to River Gowy. The quality of the flora in Thornton Main Drain matches that currently only found in ditches south of the M56 [photo 8]. Water levels have been successfully raised locally, with established, regionally important reedbeds and associated raptors. SSSI interest has been acknowledged and the site notified. All overhead power cables have been buried, redirected or removed. There are many other successful rewetting and flood relief schemes along the Gowy floodplain. Flocks of birds range up and down, moving from site to site along the wide wildlife corridor. An appropriate visitor strategy has been devised and implemented. Visitor numbers are significantly increased without appreciable increase in disturbance to wildlife. The established, species-rich hay meadows are used as a source of ‘green hay’, which is in constant demand for meadow restoration elsewhere. There is an increased demand for the high quality meat produced on the Reserve. The landholding becomes profitable without subsidies. Shell UK was so impressed by the Trust’s successful management of the land that the company agrees to sell or gift the land to CWT. 26
