Site description (2007 baseline)
These marshes extend for about 15 km along the coast on the south side of the Thames, and include areas of the inner Thames up to the Thames barrier. Habitat-types include extensive grazing-marshes, saltmarshes, mudflats and pits. Reed Phragmites and duckweed Lemna dominate the freshwater dykes, with Ceratophyllum in the more brackish dykes. Waders and wildfowl breed on the grazing-marshes, which also attract wintering raptors. The IBA attracts a wide range of wintering and passage estuarine and wetland birds.
