This comprised a desk study, Phase 1 Habitat Survey and an ecological scoping survey which assessed the potential of the site to support species of conservation concern or other species which could present a constraint to the development of the site. • The development proposals involve the creation of a new water play area comprising formation of shallow water features and erection of play equipment and associated structures within an existing farm park. • The site is approximately 0.3 ha in size and comprises grassland, a hedgerow, an existing zipwire and some juvenile trees. The surrounding land contains a small woodland copse, hedgerows, childrens play park, livestock pens and enclosures, areas of recreation grassland and footpaths. • The Preliminary Ecological Appraisal desk study identified 20 statutory designated sites within 5 km of the site and four non-statutory designated sites within 2 km of the site. The closest designated site was Horton Country Park Site of Nature Conservation Importance (SNCI) approximately 0.09 km from site. • The Phase 1 Habitat Survey identified that the site was predominantly an amenity grassland field. A native species-rich hedgerow was present along the northern boundary, wuth juvenile trees along the south of the site. A bark based zipwire and bare ground footpath were present in the east of the site. • The habitats on site provide some potential to support protected and notable species including birds, foraging and commuting bats, badgers and suitable terrestrial amphibian habitat. • A total of eight ponds were identified within 250 m of the site boundary. A Great Crested Newt (GCN) Habitat Suitability Index (HSI) survey of the four ponds on site identified that one pond provided Average suitability for GCN. The other three ponds were all assessed as providing Poor suitability for GCN. • A badger survey was also conducted at the same time as the Phase 1 Habitat Survey. No evidence of badgers or their setts were recorded within the site or 30 m from application boundary. • It is recommended that a GCN eDNA survey is undertaken on the pond that was identified as being of Average potential to support GCN (Pond 1). • No other protected species surveys are recommended but mitigation and enhancement measures have been provided. • Mitigation measures include, timing of vegetation removal to avoid the nesting bird season, retaining as many of the trees as possible. • Enhancement measures could include providing bird boxes within the site.
