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).
