The Wash

Special Protection Area

The Wash. The largest embayment in England. This phenomenal seascape on England’s east coast, extending from Lincolnshire’s windswept Gibraltar Point to the banded cliffs of Hunstanton in North Norfolk comprises a myriad of coastal habitats that support a breath-taking diversity of marine life. The birds of The Wash fly the flag for British avian wildlife.

The historic reclamation of marshlands around The Wash has left four unique near-linear tidal rivers: The Great Ouse, Nene, Welland and Witham. These rivers, flow through saltmarsh, over mud and sandflats into the deep central channels of the embayment. The Wash is dominated by saltmarsh, intertidal banks of sand and mud, sandy and shingle beaches and subtidal sandy sediments.

Intertidal mud and sand flats support a variety of polychaete worms and bivalve molluscs, including cockle and mussel beds, which alongside algae provide rich foraging grounds for many bird species. These include the dark bellied brent geese, oystercatcher, common scoter, sanderling, gadwall, curlew, pintail, shelduck, dunlin, knot, bar tailed- and black tailed godwit.

The extensive saltmarsh provides important roosting habitat for many bird species, including redshank, curlew, pintail and dunlin. The saltmarsh also houses a nutritious food resource for dark bellied brent geese, wigeon, pintail and dunlin. The latter of which also roosts alongside oystercatchers on arable fields.

The agricultural and pasture land that borders the much of The Wash saltmarsh provide foraging grounds for pink footed goose and overspill foraging for curlew, oystercatcher, dunlin and black tailed godwit when the tides are at their highest. Redshank, grey plover and black- and bar-tailed godwit enjoy unrestricted views of the surrounding area and take advantage of bare ground and short vegetation to roost. Tern species, sanderling and grey plover use the sandy, shingle and gravel beaches to roost. Wigeon roost at Wainfleet, black bout at Wolfreton Sands and pink footed goose can be found roosting at Freiston, Snettisham and Terrington.
