Site description A heathland with areas of bog and a small patch of Quercus scrub and forest. The area is contiguous with Jardelunder Moor in Germany.

Key Biodiversity The site holds one of the densest populations of Lanius collurio in Denmark. Several additional species listed on Annex I of the EC Birds Directive bred at the site in 1983 but these are no longer present, although it is hoped that Tringa glareola and Chlidonias niger will recolonize the site following habitat restoration efforts.
