List of local nature reserves in West Sussex

Local nature reserves (LNRs) are designated by local authorities under the National Parks and Access to the Countryside Act 1949. The local authority must have a legal control over the site, by owning or leasing it or having an agreement with the owner. LNRs are sites which have a special local interest either biologically or geologically, and local authorities have a duty to care for them. They can apply local bye-laws to manage and protect LNRs.

As of March 2019, there are twenty-seven LNRs in West Sussex. Nine are Sites of Special Scientific Interest, six are Nature Conservation Review sites, four are Ramsar sites, two are Special Areas of Conservation, four are Special Protection Areas, one includes a scheduled monument and two are managed by the Sussex Wildlife Trust.

West Sussex is in south-east England and it has a population of approximately 780,000. The county town is Chichester. In the north of the county are the heavy clays and sands of the Weald. The chalk of the South Downs runs across the centre from east to west and in the south a coastal plain runs down to the English Channel.
