Recent progress in managing invasive alien species in the EU

Every six years, European Union (EU) Member States report on national implementation of the EU Invasive Alien Species Regulation 1143/2014 (IAS Regulation). This briefing summarises highlights from the 2019-2024 reporting period on 87 ‘invasive alien species (IAS) of Union concern’ by all EU Member States.

Key messages

IAS of Union concern are present in the environment of all Member States. Hotspots occur mainly in densely populated areas, along rivers and near major transport hubs (e.g. harbours).

More than 300 rapid eradication response actions have resulted in almost 200 successful (full, partial or temporary) eradications of IAS populations.

More than 4,200 management measures have been implemented. More than half have successfully mitigated negative impacts on biodiversity; outcomes of the remaining measures are still pending.

All Member States identified pathways of introduction and spread and have action plans in place; 13 Member States have also established lists of IAS of national concern.

Despite progress, increased efforts are required as IAS continue to spread in the EU and new species are likely to be introduced
