National working group “Biological invasions in aquatic environments”

Created in 2008 and co-lead by Onema and Cemagref, then by the French Committee of the International Union for Conservation of Nature (IUCN) and the French Agency for Biodiversity, the national working group “Biological invasions in aquatic environments (GT IBMA) had for main objective to assist managers and decision makers.

It served as an interface for communication and discussion on IAS management and brought together more than 80 representatives of different stakeholders: managers of natural areas, researchers, associations, public institutions, state and local services, etc.

For 10 years, the GT IBMA digested and made accessible the knowledge acquired on the management methods of IAS, produced operational tools (website, management experience feedback, practical guides, etc.). It has also supported the development of strategies and public policies, and has enabled the exchange of information and the networking of stakeholders.

Building on its 10 years of experience, its positive results and the dynamic generated, the GT IBMA has now become the Scientific and Technical Expertise Network (REST) ​​of the Resource Center. It has expanded to terrestrial and marine environments to deal with all environments affected by biological invasions. Pillar of the Resource Center, the REST is mobilized to contribute to the development of tools, the identification of needs, the dissemination of knowledge or the development of training, and it supports the implementation of policies public authorities on EEE.
