✦ Synopsis

Since the present quality state of the Wadden Sea is judged more discordantly than that of the North Sea, it is examined whether the Wadden Sea is a separate ecosystem. The nutrient load into the Wadden Sea and the trend of the load are assessed. Biological indicators of the ecological state of the Wadden Sea are examined with the result that there are signs of a bad as well as of a good state. This contradiction is assigned to the fact that quality standards are absent. Self-protection mechanisms of the Wadden Sea are discussed with respect to their responsibility for the relatively good state.. A qualitative model is proposed to explain the long-term behaviour of the ecosystem.
