Invasive Alien Species - Additional external resources

The resources listed here, although hosted on external websites, were either produced by IUCN, or completed with the oversight of IUCN, and provide comprehensive and up-to-date information on the ways to prevent, manage and mitigate the impacts of IAS.

IUCN provides technical and scientific support to the European Commission for implementation of the EU Invasive Alien Species (IAS) Regulation (No. 1143/2014). The outputs listed below have been produced with the aim of supporting the application of the IAS Regulation across EU Member States, with a particular focus on the 88 species of Union concern. See here for an infographic on the EC IAS Regulation.
