An extensive area of shallow lakes, pools, reedbeds, Salix woodland and grassland which has developed on a polder (Zuidelijk Flevoland, reclaimed in 1968), having been spared from cultivation. It is situated south of the city of Lelystad, and adjoins Markermeer (038) in the north. This site, together with site 067, formed part of a single, larger site (former site NL031) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
The site is the main roost for geese Anser from feeding areas in Flevoland, and is the most important moulting area for Anser anser in north-west Europe.
Pressure/threats to key biodiversity
The main problems affecting the area are the natural succession of vegetation and the effects of botulism on wild birds (`Other' threat, above). In 1997 the area was reconnected with Lepelaarplassen (067) by a 250-m-wide stretch of marshland.
