Camilty Wind Farm remaining 38% were categorised as pipistrelle species, with 2% (one pass) recorded as Daubenton’s bat. 11.3.52 A total of 21 bat passes were recorded along the driven transect routes in all five transect surveys from May to October. The only species recorded during these surveys were common pipistrelle and soprano pipistrelle. 11.3.53 The walked transect, driven transect and automated Anabat passive detector surveys identified activity levels ranging from moderate to very low. This is to be expected as the site is dominated by coniferous woodland and is composed mainly of habitats considered of low value to bats. Comparatively higher levels of activity were recorded in the maternity season when compared to the mating/dispersal period. 11.3.54 Surveys for Nathusius pipistrelle included vantage point watches, walked transects, static Anabat surveys and driven surveys. Survey effort for the species was further increased by using an Anabat recording system at 65 m height in the met mast. The latter was deployed continuously for a total of 85 nights from 25/05/2012-04/10/2012 throughout all periods within the bat activity season with bats recorded on a total of 8 nights. The total number of files containing bat calls recorded on any one night varied between 1 – 14 bppn. A total of 28 files were recorded over the entire deployment period. No Nathusius calls were recorded on the Anabat deployed at height nor during any of the other surveys throughout the year. Great Crested Newt Legal Protection 11.3.55 Great crested newts are protected through inclusion in Annex IV of the EC Habitats Directive as translated into UK law by the Conservation (Natural Habitats, &c.) Regulations 1994 (as amended) as a European Protected Species (EPS). This species is further highlighted as a UK BAP priority species and within the Scottish Biodiversity List. Great crested newt is listed as a priority species in the West Lothian LBAP (2002). Desk Study 11.3.56 A search of NBN gateway database did not identify records of great crested newt within the ecology data search area. The consultation process did not return any records of great crested newt within the site or the ecology data search area. Field Survey Results 11.3.57 Seven ponds were identified within 250 m of the Camilty site boundary (referred to as Ponds A - G in Figure 11.7), all of which were located over 200 m from the Camilty site boundary. The HSI concluded that all of the ponds have no more than average (moderate) potential to support great crested newts (assuming the absence of fish) while Pond E is likely to have below average (low) potential. 11.3.58 Given the limited terrestrial habitat suitability, and the potential of the assessed ponds ranging from “below average” to “average” it is considered unlikely that the species is present. This assertion is further strengthened by the site’s level of isolation, with the Pentland hills providing a physical barrier to the east and south, and extensive commercial forestry present west of the site. It is considered that as a result, in those areas, connectivity with other populations at a landscape context will be minimal or even non-existent.

Camilty Wind Farm 11.3.59 In all, given the limited suitability of ponds and terrestrial habitats on site, the distance to known (historical) records (up to ten times the likely upper dispersal range of 500 m) and the isolated position of the development site in the wider landscape context it is considered unlikely that any of the assessed water bodies currently supports great crested newts. However, despite the low likelihood of the species presence, it cannot be conclusively ruled out that the species is present within, or within the zone of influence of, the proposed Camilty development. 11.3.60 It was agreed in consultation with SNH (Table 11.1) for a design alteration to be implemented by using a 300 m buffer zone around all seven ponds, which will be a no-go zone for turbines, infrastructure and any associated kind of built up structures (inset in Figure 11.7 shows the extent of this buffer, with the turbine locations shown). A distance of 300 m is used given that the species dispersal range lies predominantly within 250 m from a breeding pond (English Nature, 2004). 11.3.61 In doing so, it is considered that if the ponds supported a great crested newt population, the development would be sufficiently far away to avoid any direct impact on the ponds (i.e. habitat loss, pollution). In addition, any impact on terrestrial habitat beyond 300 m would be negligible given that it consists entirely of Sitka spruce plantation – itself of marginal suitability for newts. As such, this species is not considered further within this chapter. UK Protected Species Water Vole Legal Protection 11.3.62 Water voles are protected through Schedule 5 of the Wildlife & Countryside Act 1981 (as amended), in respect of Section 9(4) only. This species is identified as a priority species within the UKBAP, the Scottish Biodiversity List and the West Lothian LBAP (2002). Desk Study 11.3.63 The NBN database held historical records (from 1969) for this species within 10 km of the ecology data search area. The consultation process did not return any records of water vole within the ecology data search area. Field Survey Results 11.3.64 All watercourses and waterbodies were assessed for their potential to support water vole as well as for the presence of this species. 11.3.65 During the Phase 1 habitat survey possible water vole signs (runs and clippings) were found along the Shear Burn (TN18). They were not recent and no burrows or latrines were found. In isolation these observations are not considered diagnostic – i.e. they do not prove the presence of water voles. No diagnostic signs of the species were found during the dedicated water vole surveys. The majority of drainage ditches and watercourses within the survey area are considered to be unsuitable habitat for water voles. The drainage ditches along the edges of the forest tracks are exposed and devoid of suitable shelter and forage vegetation, whilst those running through forestry plantation areas do not provide banks into which water voles could establish adequate burrows. 11.3.66 Consequently, the likelihood of water voles being present on site is considered to be negligible. As such this species is not considered further within this chapter. March 2013 11-24 ES Chapter 11 Terrestrial Ecology Copyright Partnerships for Renewables Development Co. Ltd 2013 ©
