Trilateral Conference on Neobiota in the Wadden Sea - Challenges for Nature Conservation 26 August 2010   Wilhelmshaven Das Wattenmeerhaus
Trilateral Conference on Neobiota underlined the Importance of Management Plan for the Wadden Sea On 26 August 2010, the 5th Trilateral Wadden Sea Day was held in Wilhelmshaven. Over 110 participants attended the conference on “Neobiota in Wadden Sea – Challenges for Nature Conservation”. The Conference was jointly organized by the National Park Administration Lower Saxon Wadden Sea and the Common Wadden Sea Secretariat. The great response on the registration clearly showed the high relevance of this issue.

Furthermore, the experts presented proposals for prevention, management and control of invasive alien species. During the concluding discussion, priority issues were named. These were, for example, preparing an inventory of ongoing projects and activities, setting mechanisms to control introduction of alien species, using the existing framework of national, international and EU regulations for managing alien species, and enhancing cooperation between the countries by developing a trilateral management plan for the Wadden Sea.

With increasing global trade the introduction, both intentional and unintentional, has increased concomitantly and has increased in complexity. Next to global habitat loss and climate change, this biological globalization has become a key process in altering the biosphere. The Quality Status Report for the Wadden Sea 2009 has shown that in the Wadden Sea, a diverse range of alien species has established permanent populations. The rate of alien species is continuously increasing. Many of the species have become abundant and several can be regarded as invasive in the sense of having a significant effect on the recipient ecosystem.  Furthermore, with inscription of the Wadden Sea on the World Heritage List in June 2009, the World Heritage Committee encourage the State Parties to implement a strict monitoring program to control invasive species associated with ballast water, marinas and aquaculture in the property.  The conference has the aim to provide insights in recent research and management projects along the Wadden Sea coast, to assess the possible threat to the World Heritage and to discuss with scientists and managers how new challenges by marine alien species can be met by trilateral policy and management.
