Site description (2000 baseline)
An area of shallow waters, wet meadows and (landward of the dyke) improved grassland along the Frisian west coast. It is a subsite of Lake IJsselmeer (034), and lies adjacent to the Makkumer- and Kooiwaard (035) in the north. This site, together with site 035, formed part of a single, larger site (former site NL016) in the previous pan-European IBA inventory (Grimmett and Jones 1989).
Key biodiversity
Non-breeding numbers are based on aerial counts which tend to underestimate species with a scattered occurrence. The site is an important roost for geese and waders, but actual roosting numbers are poorly reflected by counts. The average seasonal peak number of waterbirds during 1992-1996 exceeded 20,000.
