Firth of Tay and Eden Estuary. 28/07/00; Scotland; 6,918 ha; 56°24'N 003°05'W. Special Protection Area, SSSI, National Nature Reserve. A complex of estuarine and coastal habitats in eastern Scotland adjacent to the city of Dundee. The site includes extensive invertebrate-rich intertidal mudflats and sandflats created by the massive sediment load deposited by the River Tay, as well as large areas of reedbed and sand dune and a small amount of saltmarsh. At least four species of wintering waterfowl are present above the 1% threshold of international importance, and on average some 48,000 waterfowl are supported there in winter, including 14 species in nationally important numbers. Some disturbance is caused in some parts of the site by large numbers of walkers and illegal use of all-terrain bicycles, but these and other potential threats are considered manageable. Students from many nearby universities conduct research on the site. Ramsar site no. 1034. Most recent RIS information: 2006.
