Site details
Site description: An area of shallow lakes and canals (former peat-workings) with fens, reedbeds, swampy woodland and wet meadows, located to the north of the city of Zwolle. The IBA is adjacent to De Weerribben (064), with which it formed a single site (`De Wieden and De Weerribben', the former site NL027) in the previous pan-European IBA inventory (Grimmett and Jones 1989). Human activities include water-sports, tourism and reed-harvesting (`Other' land-use, below).
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: A roost for geese Anser from surrounding feeding areas, but no counts are available.
Delineation rationale: 3 March 2017: area now equal to the designated Special Protection Area (Birds Directive).

Threats
Summary of threats to biodiversity at KBA: The site is threatened by the drainage of surrounding polders, commercial reed-harvesting (`Other' threat, above), and by nutrient pollution of wetlands by agricultural and industrial/urban discharges. A compensation scheme is in place for those farmers affected by restrictions on agricultural practices.
