Severn Estuary SPA
The Severn Estuary is located between Wales and England in south-west Britain. It is a large estuary, made up of mud-flats and sand-flats. The site is really important during the spring and autumn migration periods for waders moving up the west coast of Britain, as they come to feed here. In winter this area is home to a large number of waterbirds, especially swans, ducks and waders.
