A habitat-diverse site comprising shallow small and bigger freshwater lakes and numerous canals established by peat extraction activities mainly in 18th and 19th centuries, reedbeds, fens, wooded peatlands and non-wooded ones, and wet meadows. De Wieden is the most extensive lowland peatland in northwestern Europe. It is also a habitat for several rare and endangered species and communities. It acts as a water storage reservoir from drains of the surrounding polders and provides water for irrigation. Among the main human uses are tourism (with a visitors' centre), angling, boating, commercial fisheries, farming, and reed harvest. The site is threatened by drainage due to groundwater abstraction and intensive farming in the surrounding polders.
