The core of Regulation (EU) No 1143/2014 is the list of Invasive Alien Species of Union concern (the Union list), which is updated regularly.
The species included on the Union list are subject to restrictions and measures set out in the Regulation. These include restrictions on keeping, importing, selling, breeding and growing. Member States are required to take action on pathways of unintentional introduction, take measures for early detection and rapid eradication of these species, and to manage species that are already widely spread in their territory.
DG Environment has prepared a brochure including a short description of the 49 invasive alien species of Union concern (defined by the Commission Implementing Regulation (EU) 2016/1141 and the Commission implementing Regulation 2017/1263), offering brief and informal summaries of their origin, their present distribution in the EU, how they threaten our native biodiversity, and how the applicable restrictions and obligations will help mitigate their negative impacts.
