Pagham Harbour

Site overview: This site lies between Bognor Regis and Chichester in West Sussex, and the naturally occurring harbour is a tidal inlet. The Marine Conservation Zone (MCZ), a type of Marine Protected Area, protects features within the harbour area including the Ferry Pool lagoon and Church Norton spit. The site covers a total area of nearly 3 km2 - making it one of the smallest MCZs. The spit runs next to the coast which makes it a sheltered environment, so it is home to a varied and diverse number of species. This is one of just three places in the UK where the rare Defolin’s lagoon snail occurs. Seagrass beds are found in this site and act as an important food source for wildfowl, as well as a safe place for younger fish to hide.
