List of invasive alien species of Union concern

In 2016, following the EU Regulation 1143/2014 on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern. The list was first updated in 2017 and comprised 49 species. Since the second update in 2019, 66 species are listed as IAS of EU concern. Since the third update in 2022, 88 species are listed as IAS of EU concern, although the final inclusion of three of these species has been deferred to 2024, and one to 2027.

The species on the list are subject to restrictions on keeping, importing, selling, breeding and growing. Member States of the European Union must take measures to stop their spread, implement monitoring and preferably eradicate these species. Even countries in which they are already widespread are expected to manage the species to avoid further spread.
