IEEP recently conducted a project for the European Commission reviewing the EU legal and policy framework for invasive alien species (IAS). The outcomes of this project were presented in the fourth International Conference on Biological Invasions (NEOBIOTA conference) that took place in Vienna on 27-29 September and brought together 370 alien species experts from all over the world. IEEP’s work on IAS received a wide support among the conference participants and the project outcomes, including recommendations for possible future actions, formed an important element of the Resolution adopted by the conference – aiming to urge the European Commission to step up its efforts in adressing threats posed by IAS in Europe.
