Cambridgeshire County Council owns 8 Local Nature Reserves (LNRs).
- Isleham Railway Cutting
- Kingston and Bourn Old Railway
- Mare Fen
- Melwood, Meldreth
- Ring's End, Elm
- Worts Meadow
All local authorities have powers under Section 21 of the National Parks & Countryside Act 1949, to acquire, declare and manage LNRs. The process of designation involves formal consultation with Natural England, local communities and other interested parties. LNRs are normally greater than two hectares in size and are managed for people and wildlife. This management ensures that the LNR will continue to make an important contribution to local wildlife for future generations to enjoy.
The council is working with local volunteers from the community to develop 'Friends of' groups. It is also working with Parish Councils to provide local input to help with the management of the LNR sites. The council currently has groups for 5 of the nature reserves, including Isleham, Melwood, Ring’s End, Somersham and Worts Meadow.
