Every three to four years, national and regional authorities, scientific institutions, and environmental NGOs engage in topics of paramount importance for the protection of the Wadden Sea World Heritage Site.

Once per year, the members of the Expert Group Salt Marshes and Dunes (EG-SMD) meet to discuss the newest research conducted and management measures taken in relation to different habitats in the Wadden Sea.

From 2 to 3 November 2022, 16 trilateral experts held a workshop on “subtidal habitats” in the framework of the Trilateral Monitoring and Assessment Programme (TMAP) in Büsum, Germany.

With the foundation of the Common Wadden Sea Secretariat (CWSS) in 1987 by Denmark, Germany, and the Netherlands, 35 years ago, an institutionalised structure began to form. A team of two, who began on 1 November 1987, has since grown to a team of nine.

Die Erhebungen dieser im Wattenmeer bekanntesten Robbenart werden während der Fortpflanzungszeit im Juni und der Zeit des Fellwechsels im August durchgeführt.

The trilateral Wadden Sea Plan was adopted at the 8th Trilateral Governmental Conference in Stade in 1997.
