Ornithological information The raised saltmarshes are an important spring feeding area for Branta bernicla, and the area is also important as a high-tide roost for tens of thousands of waterbirds which feed in the Wadden Sea.
Site description A 22-km long area of sand-dunes on the eastern side of this barrier island in the Wadden Sea (adjacent to site 001). The width of the dunes varies from 100 m (near the main village) to 1.5 km. Other habitats include saltmarshes (Neerlands Reid), sandflats (De Hon), and intertidal mudflats. The site does not include the villages, extensive touristic facilities, or the grassland polders that are intensively used for dairy farming. Land-uses include natural-gas extraction, groundwater abstraction, hunting (restricted to rabbits), and reed-harvesting. The area lies close to an airfield.

Management considerations Threats include shellfish fisheries (Wadden Sea), gas extraction, disturbance by small aircraft (the local airfield was extended recently), reed-harvesting, and an increase in tourism (although part of the dune area is closed to the public during the breeding season). The dune area and the eastern part of the island are managed as Nature Reserves, although only small parts are actually owned by conservation bodies. The saltmarshes and mudflats are included in the SPA- and Ramsar-designated Wadden Sea.
