Site description
The estuary is fed by five major rivers (the Severn, Wye, Usk, Parrett and Avon) in addition to other lesser rivers. Classically funnel-shaped, the estuary has the second widest tidal range in the world and is characterized by strong currents, mobile sediments and high turbidity. Large expanses of cord-grass Spartina occur. The site supports internationally important numbers of wintering and passage wildfowl and waders, in addition to important breeding bird populations.
