Tetney Marshes

Flock of waders landing on mudflats at sunset

Tetney Marshes covers over 1,500 hectares of coastal mudflats, salt marsh, dunes and saline lagoons on the north Lincolnshire coast. The reserve forms an important part of the Humber estuary, which is one of the top five estuaries for birds in the UK, with at least 175,000 birds using the estuary during the winter months. The site is designated as Site of Special Scientific Interest and Special Protected area and protected under both UK and EU legislation. The RSPB has managed the reserve since 1975 to safeguard these important habitats for wildlife. Large areas of intertidal mud and sand supports up to 50,000 wintering and passage waders and wildfowl including nationally and internationally important numbers of brent geese, knots, grey and golden plovers and sanderlings. Salt marsh covers 289 ha of the reserve and is one of the largest areas of this threatened habitat on the east coast north of the Wash. The marsh holds an important population of around 70 pairs of breeding redshanks and attracts wintering twites and hen harriers. The saline lagoons support a specialist community plants and animals including the rare lagoon sand shrimp, which occurs here at its northernmost site in the UK.
