Benfleet and Southend Marshes SPA
This site is on the north shore of the outer Thames Estuary in southern England. The site comprises a large area of saltmarshes, cockle shell banks, mud-flats and grassland. These areas provide an excellent feeding ground for a wide range of wintering wildfowl and waders. In fact, over winter, the area regularly supports over 34,000 individual waterfowl, including dunlins, ringed plovers, oystercatchers, knots, grey plovers and dark-bellied brent geese.
