Site description This site comprises the sand-dunes of the barrier island Terschelling in the Wadden Sea, from an extensive sandflat in the west (Noordvaarder) up to De Boschplaat (006) in the east. In the south it is bordered by villages, grassland polders and conifer plantations. There are shifting and fixed dunes, with the latter covered in herbaceous vegetation or crowberry Empetrum nigrum, as well as humid dune-slacks. Land-uses include scattered holiday-houses, recreational facilities, hunting, and groundwater abstraction. This site, together with site 006, formed part of a single, larger site (Terschelling, former site NL005) in the previous international IBA inventory (Grimmett and Jones 1989).
