There are three local nature reserves in Epsom and Ewell, all looked after by Epsom and Ewell Borough Council:
The largest Local Nature Reserve in Surrey, part of a Site of Special Scientific Interest (SSSI) and part of Ashtead Common National Nature Reserve. The site has a number of habitats including woodland, grassland, scrub and remnants of heathland. The common also has several ponds. There are more than 400 species of trees and plants and a range of insect, mammal and bird species. Rare flowering plants, such as the common spotted and southern marsh orchids are also found on Epsom Common, along with pollarded oak trees, which are several hundred years old and home to a number of rare insects, such as purple emperor and white admiral butterflies. The Epsom Common Association website has more information.
Hogsmill Local Nature Reserve
Situated in the northern part of the borough and comprises 33.42 hectares of wild open space with a network of grass and surfaced paths. For those wanting to explore a wild part of the borough this is a good site. There are many different bird species to be found, including kingfishers.
Horton Country Park
A Local Nature Reserve and Site of Nature Conservation Importance (SNCI). Its variety of habitats harbour rich and varied plant and animal communities. Of particular importance are the communities associated with woodland, some of which is known to be 'Ancient' coppice woodland, meaning that it was present before 1600.
