The policy brief entitled “Action on invasive alien species should better anticipate climate change effects on biological invasions in Europe” is based on the combined results of the WhoIsNext, INVAXEN and Resipath projects. This 4-page brief presents key recommendations on measures for the implementation of the Alien Invasive Species policy by Member States and the European Commission. These projects have demonstrated how the use of distribution modelling tools under different climate scenarios to inform invasive alien species risk assessment would be an efficient and reliable tool to focus and prioritise global and national efforts against biological invasions. The brief further introduces the example of a continent-wide early detection and rapid response system for invasive alien garden plants in Europe under different climate scenarios.
