WADDEN SEA AND HALLIG ISLANDS OF SCHLESWIG-HOLSTEIN

 
       
  General Description   The Wadden Sea is a coastal area with tidal flats, a tidal rhythm of approximately 12 hours and a tidal amplitude of about 2.5 m. Some islands and sandbanks lie above the mean high water mark. The near shore areas are covered with salt resistant vegetation (salt-marshes).It includes:· Beaches, sand flats and sandbanks: These generally lack vegetation cover and lie between the mean high tide mark and the spring-tide high water mark. Pure sandy beaches can be found in the surf zone.· Salt-marshes: These form the natural transition zone between the tidal flats and the mainland, islands and Hallig islands. This semi-terrestrial habitat is formed naturally in areas where water currents and wave action are reduced, sedimentation of sand and mud can occur and the first pioneer plant species can settle. Salt-marshes can tolerate flooding by saltwater because the plants living there are adapted to high salt levels. Salt-marshes occur in the region between 40 and 50 cm above the mean high tide line.· Tidal mudflats and sands: high-lying mudflats and sandbanks that fall dry at low tide (eulittoral). Tidal flats are geo-morphologically flat and are divided by creeks and channels. They are often structured by sand ripples and tracks and signs of animals.· Creeks and channels: Creeks and channels extend into the tidal flats from the North Sea to the mainland. They are up to 4 km wide and many of them still contain water up to 1 m deep at low tide.· Marine area to the west in the transition zone between the Wadden Sea and the open sea (down to the 15 m below sea level)Human population in the Core Area 8, in the Buffer Zone 10 and in the Transition zone 459.Core and buffer zones are managed by the State of Schleswig-Holstein, State Ministry of the Environment, Nature Conservation and Agriculture State Office for the National Park Schleswig-Holstein Wadden Sea. The transition zone lies in the County of Nordfriesland in the districts of Pellworm and Nordstrand and includes the municipalities Hooge, Langeneß/Oland, Gröde and Nordstrandischmoor.

  Brief description   Trilateral Monitoring and Assessment Programme (TMAP) with its implementation phase 1994-1997 and operation phase since 1997. Implementation of the Common Package in 1997 including all parameters that are important for the ecosystem.COSA (Coastal Sands as Biocatalytical Filters) Research carried out together with Polish, Dutch, Danish and German scientists.MINOS (Marine Warm-blooded animals in the North and Baltic Seas), applied research on porpoises, seals and seabirds in connection with the development of offshore wind parks.Socio-economic monitoring is carried out with relation to the National Park.
