Monitoring the Wadden Sea

The joint Trilateral Monitoring and Assessment Programme - TMAP

Established in 1992, the Trilateral Monitoring and Assessment Programme is the common monitoring programme of the Wadden Sea states. The programme covers the entire Wadden Sea, including islands and offshore areas and spans a broad range of topics, from physiological processes to population development and changes in landscape and morphology.

The TMAP supports integrated management and assessment of the World Heritage Site. It provides significant added value for the Trilateral Wadden Sea Cooperation (TWSC) as it:

  1. Provides an important and scientifically sound evidence base for decision-making and policy development at all levels.
  2. Provides essential contextual information to support the management of the Wadden Sea as a single ecological entity.
  3. Supports reporting against directives and the World Heritage status.
  4. Enables integrated assessment to be undertaken, which is an essential prerequisite for the application of the ecosystem approach.
  5. Provides information about progress towards Trilateral Targets and facilitates the discussion about the priorities for the period ahead.

The TMAP is carried out by national and regional authorities in charge of monitoring. The main partners are:

  • Danish Ministry for Food and Environment, Nature Agency
  • German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety,
  • State Ministries for the Environment in Schleswig-Holstein, Hamburg and Lower Saxony, and the National Park Administrations,
  • Dutch Ministries of Economic Affairs

Technical groups, like the Trilateral Data Handling Group (TDG), the Coordinator Group on the Joint Monitoring Programme for Breeding Birds (JMBB) and the Coordinator Group on the Joint Monitoring Programme for Migratory Birds (JMMB) have been installed under the responsibility of the Task Group Management and Monitoring (TG-MM).

In the framework of the TMAP, the Common Wadden Sea Secretariat is responsible for the day-to-day management of the programme and the preparation and of the technical monitoring groups.
