IJsselmeer. 29/08/00; Friesland, Flevoland, Noord-Holland; 113,341 ha; 052°45’N 005°27’E; Natura 2000 (SPA,SAC). The boundaries of the Ramsar Site have been aligned to the Natura 2000 site, resulting in an increase of 5,220 ha. IJsselmeer was cut off from the Wadden Sea by Afsluitdijk causeway in 1932, and about 45% of the territory was reclaimed as polders. Presently it is a vast shallow freshwater lake, the largest freshwater basin in the country. The Site regularly supports more than 20,000 wintering waterbirds as well as endangered bird species such as ruff, bittern, avocet and spotted crake. IJsselmeer plays a crucial role in regulation of hydrology in the northern Netherlands – it acts as a drain for the surrounding land and water is discharged into the Wadden Sea through Afsluitdijk or into the North Sea via Markermeer and the North Sea Channel. Human activities include tourism, commercial fisheries, shipping traffic and sand extraction. The site is threatened by artificial water level management, intensive commercial fishing, industrialization, urbanization and the construction of wind farms. Ramsar Site no. 1246. Most recent RIS information: 2013.
