Other Site Characteristics

Former tidal estuary of the Rhine/Maas system, completely closed off from the Oosterschelde (028) in 1987. It also adjoins SPA Grevelingen (NL9802021) in the west, SPAs Haringvliet/ Hollands Diep (NL9802018-19) in the north, and is linked with the Zoommeer (NL9902010) via the Schelde-Rhine river connection (shipping lane to Antwerp). The 20-km long stagnant freshwater lake includes some islets, mudflats and former saltmarshes. Formerly named SPA Volkerakmeer.

4.2 Quality and importance

An important site for breeding Recurvirostra avosetta, Charadriusalexandrinus (max. 184 pairs, 1989) and Sterna albifrons, but numbersare decreasing due to vegetation succession. The best breeding site forLarus melanocephalus in the Netherlands.Species meeting the 1% threshold (breeding): Avocet Recurvirostra avosetta (4%); (non-breeding): Great Crested Grebe Podiceps cristatus (2%); Great Cormorant Phalacrocorax carbo (1%); Eurasian Spoonbill Platalea leucorodia (7%); Mute Swan Cygnus olor (1%); Greylag Goose Anser anser (1%); Barnacle Goose Branta leucopsis (1%); Gadwall Anas strepera (6%); Northern Pintail Anas acuta (4%); Northern Shoveler Anas clypeata (5%); Tufted Duck Aythya fuligula (2%); Common Goldeneye Bucephala clangula (1%); Common Coot Fulica atra (1%); Avocet Recurvirostra avosetta (2%).One of the five most important sites for (breeding): Avocet Recuvirostra avosetta, Mediterranean Gull Larus malanocephalus, Little Tern Sterna albifrons; (non-breeding): Horned Grebe Podiceps auritus.The site regularly supports more than 20,000 wintering waterbirds: average peak number 81,548 (1991/92-1995/96).Site largely overlaps with IBA 026 (IBA2000).
