          the most acute problems include habitat destruction, the co-
        
        
          inciding of recreational activities with breeding periods of
        
        
          rare species, and increasing populations of predators.
        
        
          The Wadden Sea is also regarded as the most impor-
        
        
          tant wetland for migrating waterbirds on the „East Atlantic
        
        
          Flyway” which, via the birds, ties such different geographic
        
        
          areas as the high Arctic tundras in Siberia, Greenland and
        
        
          northern Canada together with coastal wetlands in western
        
        
          and southern Africa. It is estimated that the Wadden Sea is
        
        
          of international importance for at least 52 geographically
        
        
          separate populations of 41 species.
        
        
          The Danish Wadden Sea plays a role for migrating
        
        
          waterbirds all year round as a feeding, resting and moul-
        
        
          ting area, and when most populations reach their peak in
        
        
          autumn, it is not uncommon to be able to count between half
        
        
          a million and a million waterbirds at a time. And if the focus
        
        
          is on the impacts on the waterbirds, which can be limiting
        
        
          or threatening to the many populations, the most significant
        
        
          is reckoned to be the acute threat of pollution of the marine
        
        
          environment, the increasing number of recreational activi-
        
        
          ties and the types of fishing which can affect species, both
        
        
          in terms of food supply and disturbances.
        
        
          Protection of birds in the Wadden Sea is a concept which
        
        
          has been known for many years, and the first bird reserves
        
        
          were established as early as 1907 and 1939. But it was not
        
        
          until the 1970s that the need to provide better protection
        
        
          for the Wadden Sea’s unique natural environment and bird-
        
        
          life grew significantly. There was considerable focus on
        
        
          the hunting of migrating waterbirds, and it was decided to
        
        
          create Denmark’s biggest game reserve in the Wadden Sea
        
        
          in 1979, following which the Wadden Sea became a nature
        
        
          protected area in 1982, and it has since been managed in
        
        
          accordance with a comprehensive regulation on the Nature
        
        
          and Game Reserve Wadden Sea.
        
        
          Apart from the national legislation, Denmark, Germany
        
        
          and The Netherlands have sought to coordinate the admini-
        
        
          stration and protection of theWadden Sea since 1982 via the
        
        
          Trilateral Wadden Sea Cooperation. Apart from this govern-
        
        
          mental partnership, the Danish Wadden Sea is also cove-
        
        
          red by the Ramsar Convention (since 1977), the EC Bird
        
        
          Protection Directive (since 1979/1994) and the EC Habitat
        
        
          Directive (since 1992/1998), and work is currently in pro-
        
        
          gress on designing the provisions in the EU-based directives
        
        
          and agreements via the so-called NATURA 2000 planning.
        
        
          In general terms, the many years of Danish, German,
        
        
          and Dutch initiatives for the Wadden Sea have gradually,
        
        
          and especially the over 25 years with the Danish nature and
        
        
          game reserve, borne fruit and had positive effects on a large
        
        
          part of the highly significant occurrences of both breeding
        
        
          and migrating birds which are so characteristic of the area.
        
        
          But as the protection is still limited to parts of the birds’
        
        
          habitats, and as new problems are continually arising in re-
        
        
          lation to the birds’ wellbeing in the Wadden Sea area, the
        
        
          future will also present a challenge to be met in adapting
        
        
          the reserve such that its administration becomes even better
        
        
          and more sustainable. Finally, it will also be a challenge to
        
        
          establish a Wadden Sea national park in such a way that it
        
        
          includes a balance between use and protection of the unique
        
        
          landscape and nature area which the Wadden Sea truly is.
