WWT Martin Mere is a wetland nature reserve and wildfowl collection managed by the Wildfowl and Wetlands Trust at Tarlscough, Burscough, Lancashire, England, on the West Lancashire Coastal Plain, 6 miles (10 km) from Ormskirk and 10 miles (16 km) from Southport (Merseyside).

[7] The name of the centre comes from the mere[8] on the west side of the reserve which is ringed by more than ten observation hides.

[9] Martin Mere has its own "Domesday Book", listing (for 2002)[10] nationally important species of wildlife found at the reserve, other than birds include the whorled caraway (Carum verticillatum ), at its only site in England away from the southwest, and the regionally scarce water dropwort (Oenanthe fistulosa).

[12] This reserve is at its best in winter, attracting huge flocks of pink-footed geese and Eurasian wigeon, many whooper swans and occasional rarer birds such as the snow goose.

The reserve and centre were the concept of haulage contractor, Ronnie Barker, who was a friend of Sir Peter Scott.
