Site description (baseline)
A small, crescent-shaped island in the western part of the Wadden Sea (site 001 encloses the entire site) with beaches, intertidal mudflats and sandflats, and raised saltmarshes. The island was reinforced by building a 2.5 km long dyke on the northern side in 1987 with sand supplementation in 1988 to enlarge the breeding area for terns Sterna.

Key biodiversity
The area is important as a breeding site for terns Sterna, and as a high-tide roost for tens of thousands of waders which feed on the surrounding mudflats.
