Abstract
The Danish part of the Wadden Sea comprises 1.500km2 and makes up about one tenth of the whole Wadden Sea area. In contrast to the other parts of the Wadden Sea the water quality in the Danish section is not influenced by large rivers, but mostly inputs from the North Sea. During 1990–2010 nitrogen in the water body has been nearly halved. The Houting, an endemic fish species may now been secured due to intensive river restoration. The breeding birds occur numerous, but the populations of many species have decreased recently. Millions of water birds stay during spring and autumn, and the site is of international importance to 20 species. Sea mammals like the Harbour seals are numerous, and the small population of Grey seal increase in number. The Danish part of the Wadden Sea is well protected, but still under pressure from changes in land use and recreational activities.
