The Wash SPA
This site is located on the east coast of England and is the largest estuarine system in the UK. It is fed by the rivers Witham, Welland, Nene and Great Ouse that drain from much of the east Midlands of England. The intertidal flats here are full of small worms, along with beds of glasswort which act as a food source for a large numbers of waterbirds. This is also a breeding ground for shellfish including mussels, cockles and shrimps. These provide food for oystercatchers. Large numbers of geese, ducks and waders live here, both in spring and autumn. Over half of the total population of Canada/Greenland breeding knots live here.
