The Site is a complex of shallow marine waters and adjacent low-lying wet meadows along the coast of the Kattegatt Sea. Important habitats include shallow bays, lagoons and islands, rocky shorelines, sand dunes, salt meadows, moors, mudflats and reefs. The flat shore meadows are unique in the European Continental Region and are of great ecological importance for plants and staging and breeding waders. The combination of grazed meadows and mudflats supports nesting waders and is a staging area for migratory birds such as the locally vulnerable garganey Anas querquedula, common eider Somateria mollissima and little tern Sternula albifrons. Human activities include fishing and other recreational activities. The main threats to the ecological character of the Site include housing and urban areas, recreational activities such as camping and windsurfing, and wind turbines. Continued grazing by cattle is essential to the ongoing condition of the shore meadows.
