BiodivERsA policy brief: action on invasive alien species should better anticipate climate change effects on biological invasions in Europe

BiodivERsA has announced the publication of a new policy brief entitled "Action on invasive alien species should better anticipate climate change effects on biological invasions in Europe". The brief is based on the combined results of three BiodivERsA projects*. Invasive alien species (IAS) are species that are introduced intentionally or accidentally to Europe, where they are one of the biggest threats to biodiversity and ecosystem services, and damage agriculture, forestry, infrastructures and human health. The policy brief presents key recommendations on measures for the implementation of the IAS policy by Member States and the European Commission.The key recommendations are:

  • Include climate-distribution modelling under different IPCC climate scenarios in horizon scanning to identify alien species that have the potential to be invasive in the future due to climate change, and to screen out species with a low risk of invasion.
  • Include an assessment of the likely species range change in Europe in response to climate change in the risk assessment of invasive alien species identified as high priority in the EU.
  • Introduce an EU-wide early detection and rapid response system for alien garden plants in Europe to anticipate potential invaders under future climate scenarios.

The policy brief can be found on the BiodivERsA website

*: WhoIsNext, INVAXEN and Resipath. WhoIsNext assesses which ornamental plant species will most likely establish and become invasive, and which regions of Europe will most likely be affected by invasions, under climate change. INVAXEN aims at better understanding the biology, dispersal patterns, physiology, invasive potential, and impact on local populations, of X.laevis. RESIPATH aims at studying how European forest communities have been affected by and responded to invasive pathogens and also to develop means to mitigate the impact of invasive pathogens.
