Ribble and Alt Estuaries SPA

Status: Designated

Description

Site overview

This site lies on the coast of Lancashire and Merseyside in north-west England. It is made up of two estuaries, of which the Ribble Estuary is by far the larger, together with an extensive area of sandy foreshore along the Sefton Coast.  This site is part of the chain of western Special Protection Areas (a type of Marine Protected Area) that fringe the Irish Sea. It is a hugely important area for birds, in fact over winter this area supports more than 301,000 waterfowl.  During winter swans, geese, ducks and waders flock here.  A large proportion of this site is within the Ribble Estuary National Nature Reserve.
