County Wildlife Sites (CWS), known nationally as Local Sites, are considered to be of value for wildlife in a county context. There are over 1,300 CWS in Norfolk, most of which are privately owned and have no public access. The CWS system in Norfolk is managed by a partnership of Norfolk Wildlife Trust, Norfolk Biodiversity Information Service (NBIS), Norfolk County Council, Norfolk Biodiversity Partnership, Natural England, Environment Agency and the Broads Authority, with NWT taking the lead role.
While CWS do not receive statutory protection, they are given some protection through the planning system, with NWT playing the key role in advising planning authorities, developers and others on their protection. There is no legal constraint on the management of these sites, but NWT works with many landowners across Norfolk, giving help, advice and support with management.
