  • Group: A = Amphibians, B = Birds, F = Fish, I = Invertebrates, M = Mammals, P = Plants, R = Reptiles
  • S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
  • NP: in case that a species is no longer present in the site enter: x (optional)
  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
  • Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics

An extensive area of coastal waters of the North Sea, extending from Rotterdam in the north up to the Westerschelde estuary in the south. The site also adjoins the closed-off delta area of the Rhine/Maas river system including six other Natura 2000-sites, and is close to Vlaamse Banken in Belgium. It contains shoals, mud and sand flats, beaches, sand-dunes and raised saltmarshes. Important habitats include shallowly submerged sandbanks and intertidal mud- and sandflats.

4.2 Quality and importance

The following data refer to the period 1993-1997 (data in paragraph 3.2a-b refer te period 1999-2003). 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).Species meeting the 1% threshold (non-breeding): Eurasian Spoonbill Platalea leucorodia (3,3%), Greater Scaup Aythya marila (1,8%), Grey Plover Pluvialis squatarola (1,0%), Common Redshank Tringa totanus totanus (1,7%).The site regularly supports more than 20,000 wintering waterbirds: average peak number 39,000+ (1992/93-1996/97, not all species included).One of the five most important sites for (non-breeding): Red-throated Diver Gavia stellata, Horned Grebe Podiceps auritus.Site largely overlaps with IBA 020-21 (IBA2000).
