Annex 4 of the 2014 Tønder Declaration

Strategic Framework Alien Species

The overall objective of the Strategic Framework is to prevent threats to the Wadden Sea ecosystem and biodiversity through alien species. This will be done by

  • Preventing alien species from entering the Wadden Sea Area
  • Minimising further spread of alien species once they have been detected in the Wadden Sea Area
  • Eradicating, if feasible, alien species that have become established in the Wadden Sea Area and are assessed as (potentially) invasive

Several approaches provide recommendations for management of alien species in the Wadden Sea (e.g. national strategies and/or action plans and various publications, amongst them the QSR 2009). There is general agreement that efforts to address alien species in the Wadden Sea should focus on five main elements:

  1. Prevention
  2. Early Warning/Detection and rapid response  
  3. Eradication and control
  4. Raising awareness
  5. Implementation
