Site description (baseline)
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.

Key biodiversity
This is the main feeding site for Branta leucopsis and B. bernicla in winter, in the Netherlands at least, and possibly over a much greater area. The saltmarshes and polders are an important high-tide An important area for non-breeding Platalea leucorodia and a wide variety of waterfowl.
