Site description An extensive area of intertidal mudflats, saltmarshes, and grassland polders outside the Wadden Sea dyke of Friesland (total length 40 km). The site is contiguous with the Wadden Sea IBA (site 001), and adjacent to Lauwersmeer (015) in the east. Land reclamation by the furthering of natural accretion (intensified since the 1930s) has ended, but the existing system of dams and ditches will be maintained to reduce erosion.
