The site is approximately 20 hectares in size and contains a range of habitat types that are typically associated with disused quarries. The quarry floor supports agriculturally improved grassland surrounded by a mixture of vegetated and bare limestone cliffs. In addition, there are spoil mounds located within the quarry void that are characterised by steep, eroding sides, which support a sparse open vegetation community and a flat plateau of improved grassland. Above the quarry void, there is a thin strip of land to the south and west, which supports calcareous and neutral grassland with scattered trees and shrubs. Improved pasture adjoins the south, east and west boundaries. The north of the site supports vertical and very steep slopes that consist of semi-mature and mature broadleaved woodland. The edge of this woodland is defined by the A6 Buxton to Matlock road. On the north side of the A6 is the River Wye which is bordered by broadleaved woodland. Towards Buxton lies the former Sewage Treatment Works site which, following restoration, is now planted with broadleaved trees. Beyond the improved pasture grasslands on the east side of the site there is a small dale that supports a mixture of habitats including neutral and calcareous grassland, broadleaved woodland and tall herb stands that are located on steep slopes and rocky outcrops. The study site is set in a typical landscape for this part of Derbyshire, which consists of improved grasslands and small woodlands on the plateaus and the less steep slopes of the dales. The numerous quarries and steep-sided valleys add topographical variation to the local landscape. 1.2 Proposed Works Express Parks Buxton Ltd is proposing to develop the quarry void for industrial, recreational and educational purposes. Works will include the removal of the spoil mounds along the northern edge of the site. The development will be located within the floor of the former quarry. 1.3 Aims of Study Baker Shepherd Gillespie was commissioned by Glentoal Associates on behalf of Express Parks Buxton Ltd to undertake an Extended Phase 1 Habitat Survey of the site, in order to identify habitats or species that may be affected by the proposed works, and provide a preliminary ecological assessment. The objectives of the survey were to: • Identify the existing habitats within and adjoining the site; • Check for evidence of protected species within and adjoining the site; • Assess the potential for protected species to be present in the area; • Identify potential ecological impacts relating to the proposed works; • Identify requirements for further survey; • Propose mitigation measures to avoid and reduce ecological impacts, as far as these can be determined at this stage. 4500_002_rpt_mw_gt.doc Page 2 Express Parks Ltd Cowdale Development 2 Methodology 2.1 Desk Study A desktop study was carried out to determine the presence of any protected or notable species records for a 2km radius around OS grid reference SK 079 723 and for statutory or non-statutory designated sites of nature conservation value (such as Sites of Special Scientific Interest (SSSIs), Special Area of Conservation (SAC) or Local Wildlife Sites (LWS), within a 5km radius of the site. The Derbyshire Wildlife Trust was contacted to supply some of this information and Natural England’s nature-on-the-map website1 was consulted to determine the locality of statutory protected sites within 2km of the study site. 2.2 Field Survey Philippa Harvey MIEEM (Principal Ecologist) and Mark Woods MIEEM (Senior Ecologist) undertook a walk-over field survey on 7th October 2009 between 0900 and 1530 hours. The weather was sunny with light winds and an average temperature of 160C. The site was walked over and the habitats were described using the Phase 1 Habitat Survey methodology2. Checks for signs of protected species were made throughout the site. Scattered and woodland trees were inspected to assess their potential to support roosting bats. Habitats were assessed for their suitability to support nesting birds. Searches were also made for evidence of badgers Meles meles (such as setts, dung pits, hairs and tracks) and water vole (such as burrows, feeding remains, droppings and tracks). The site was also searched for the presence of the invasive non- native plant Japanese knotweed Fallopia japonica. 3 Results 3.1 Desk Study 3.1.1 Designated sites 3.1.1.1 Statutory Designated Sites A number of statutory sites of nature conservation interest were located within 5km of the site, including the Peak District Dales Special Area of Conservation (SAC) and the Peak District Moors Specially Protected Area (SPA) and South Pennine Moors SAC. • Wye Dales SSSI is located 0.4km to the north of the site at its nearest point (Cunning Dale), centred at OS grid reference SK 154 722. Other dales included within the Wye Dale SSSI such as Deep Dale and Woo Dale are located within 2km distance, to the west of the study site. 3.1.1.2 Non-statutory designated sites Four Local Wildlife Sites: (LWS) and one “recorded site of interest” are located within 2km of the site. A LWS is identified as having county level importance for its nature conservation interest. • Cow Dale, which forms the eastern edge of the survey area, is an unimproved calcareous grassland site and is designated as a LWS (HP 176), covering an area of 8.64 Ha. Approximately half of this LWS (3.79 Ha) is identified as a semi-natural grassland. 1 www.natureonthemap.org.uk/ 2 JNCC, 1993.
