Chesil Beach is a major shingle beach and provides a maritime shingle environment. The seaward side of the beach is highly mobile under storm conditions and cannot support any plant communities. The eastern side of the beach is much more stable enabling plant communities to establish. In some areas the beach is sufficiently stable for a turf to form, particularly at Ferrybridge.
The Fleet Lagoon is a shallow area of saline water between Chesil Beach and the mainland. It is 13 km long. Its width varies from 900 metres at Littlesea down to just 65 metres in the Narrows. The deepest part is 4-5 metres deep, but all of the mid and upper Fleet is less than 2 metres deep.
The four lists located on the drop down menu at the top of the page show the species that have been recorded on the beach, lagoon and the land shore.
