Site description
An area of sandbanks and shallow waters, with a small reedbed and an embanked grassland polder, along the Frisian south coast. It is a subsite of Lake IJsselmeer (034).



Key biodiversity
The site is an important roost for geese Anser (from Noordoostpolder) and waders, but no recent counts are available. Non-breeding numbers are based on aerial counts which tend to underestimate species with a scattered occurrence. This is the main moulting area for Podiceps cristatus in the Netherlands (up to 20,000). The mean total number of wintering waterbirds exceeds 20,000.



Pressure/threats to key biodiversity
The main problems are water management (the water-level is deliberately kept high during summer), disturbance by boating, and excessive reed-harvesting (`Other' threat, above).
