Chichester Harbour is a large natural harbour in West Sussex and Hampshire. It is situated to the south-west of the city of Chichester and to the north of the Solent. The harbour and surrounding land has been designated as an Area of Outstanding Natural Beauty (AONB) and a biological and geological Site of Special Scientific Interest (SSSI). The area is also part of the Solent Maritime Special Area of Conservation, Chichester and Langstone Harbours Ramsar site, Special Protection Area and Nature Conservation Review site, Grade I. Part of it is a Geological Conservation Review site and two areas are Local Nature Reserves. Chichester Harbour is a area that is managed by Chichester Harbour Conservancy, an independent public body that was established by an Act of Parliament in 1971. Description Chichester Harbour is one of four natural harbours in that area of the coastline, the others being Portsmouth Harbour, Langstone Harbour and Pagham Harbour. It is one of the few remaining undeveloped coastal areas in Southern England and remains relatively wild. Its wide expanses and intricate creeks are at the same time a major wildlife haven and among some of Britain's most popular boating waters. The massive stretch of tidal flats and saltings are of outstanding ecological significance. Very large populations of wildfowl and waders use the mudflats feeding on the rich plant life and the huge populations of intertidal invertebrates. More than 7,500 Brent geese overwinter on the intertidal mud-land and adjacent farmland and around 55,000 birds reside in or visit the Harbour throughout the year. The harbour is one of the south coast's most popular sailing waters with as many as 12,500 craft regularly using the harbour, with competitive racing taking place among the 14 sailing clubs of the Chichester Harbour Federation. The villages, sea walls and footpaths are a popular leisure area for residents and tourists alike. Set up by the Chichester Harbour Conservancy Act 1971, Chichester Harbour Conservancy has the duty to conserve, maintain and improve the harbour and amenity area for recreation, natural conservation and natural beauty. As well as being the statutory harbour authority, the Conservancy manages the Area of Outstanding Natural Beauty (AONB). To the south west of the entrance to Chichester Harbour is Chichester Bar, a shallow spit which can present a significant navigation hazard at all states of the tide. The entrance to the harbour is deep with a fast tidal stream
