There are three local nature reserves in Reigate and Banstead, looked after by Reigate and Banstead Borough Council.
Earlswood Common in Redhill contains parkland, woodland and lakes and is a Site of Nature Conservation Interest (SNCI).
A Site of Special Scientific Interest (SSSI) consisting of open heath and acidic grassland. The site also contains alder woodland and some marshy meadows which are the only ones of this type remaining in Surrey. The marshy meadows contain a colony of the rare southern marsh orchid.
Banstead Woods and Chipstead Downs
This wonderful ancient woodland and rare chalk grassland habitat has become the newest Local Nature Reserve in the borough, having been awarded designation in June 2017. The majority of the LNR is also designated a Site of Special Scientific Interest (SSSI). The LNR is actively managed in partnership for wildlife and people by the borough council's Greenspaces team, Downlands Partnership and local Wood Chip conservation volunteer group, through practical conservation work and grazing with livestock. Banstead Countryside Walk and Nature Trail are now complemented by a new family 'Narnia-themed' walking trail.
