The area includes the most interesting parts of the coastal polders to the north of Brugge which consist of grasslands, extensively used ditches, canals and reedbeds. It also includes a small part of the coastal dunes near Blankenberge.
This is an internationally important wintering site for Anser brachyrhynchus, A. albifrons and Anas penelope. The area is also important for breeding meadow birds.
