Site details
Site description: A stagnant shallow freshwater lake with reedbeds and wet meadows, which was cut off from the Oosterschelde (028) in 1983. It is adjacent to the Zoommeer (029) in the north-west, with the city of Bergen op Zoom at the north-eastern border, and the Schelde-Rhine river connection at the west side. This site, together with sites 028 and 029, formed part of a single, larger site (former site NL050) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: The site is a roost for geese Anser from surrounding feeding areas, but no counts are available.
Delineation rationale: 9 March 2017: area edited. Now equal to the designated Special Protection Area (Birds Directive).
