An extensive area of coastal waters of the North Sea, extending from Rotterdam in the north up to the Westerschelde estuary (032) in the south. The site also adjoins the closed-off delta area of the Rhine/Maas river system, which includes seven other IBAs (021-024, 027-029), and is close to Vlaamse Banken in Belgium. Important habitats include shallowly submerged sandbanks and intertidal mud- and sandflats. This site, together with sites 022 and 023, formed part of a single, larger site (former site NL046) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
In winter this area holds fluctuating numbers of Aythya marila (max. 5,550, 1992/93), Somateria mollissima (max. 9,968, 1992/93) and Melanitta nigra (max. 20,000, 1986/87). The mean total of waterbirds in February (1992/93-1994/95) exceeds 20,000.
