Littoral survey of the Ribble, Duddon and Ravenglass estuary systems, east basin of the Irish Sea 1992
Marine JNCC Publications Seabed Habitats and Geology 0963-8091 Coastal and Estuarine JNCC report series Marine 37
The Ribble, Duddon and Ravenglass estuary systems were surveyed in June 1992 as part of the Marine Nature Conservation Review (MNCR), which was a project initiated by the Nature Conservancy Council (NCC) in 1987 to consolidate the information already collected on British marine ecosystems.
The Ribble, Duddon and Ravenglass estuarine systems enter the eastern basin of the Irish Sea. The Ribble Estuary is a large coastal plain estuary with sandy outer shores and a series of saltmarshes fringing the inner muddy shores. The Duddon Estuary has extensive mobile sand-flats at the entrance, becoming progressively muddier towards the upper tidal limit. The Ravenglass estuarine system is formed from three estuaries – the Esk, Irt and Mite; it is sandy in the outer estuary and muddy in the inner estuary.
From this survey, 140 taxa were recorded in 76 habitats from 25 sites. A total of ten community types were identified: six hard substrata and four sedimentary communities.
