Spread of the Pacific Oyster in the Wadden Sea

Causes and consequences of a successful invasion

Conclusions and Recommendations from the Trilateral Workshop on Pacific Oyster invasion in the Wadden Sea (22 March 2007). Interreg IIIB - HARBASINS Project.

In this 2007 report for the first time a comprehensive data compilation of the entire Wadden Sea was carried out in the framework of the Trilateral Monitoring and Assessment Programme (TMAP) to document the spread of the Pacific Oyster with special emphasis on the recent strong increase. The report aims to provide support for reporting and assessment under the EU Water Framework Directive and Habitats Directive and to support necessary updates of TMAP.
