The Act on Managing the Risk Caused by Alien Species (Laki vieraslajeista aiheutuvien riskien hallinnasta 2023) lays down provisions on how the EU Regulation on Invasive Alien Species is to be implemented in Finland. In addition, the Act contains provisions on invasive alien species which are not included on the List of species of Union concern but which can be considered harmful in the Finnish environment. Provisions on the national list are laid down in a Government decree. The list is being updated as necessary.
Since these species are classified as invasive alien species in Finland their importation, cultivation, sales and other possession or release into the environment are prohibited.
So far, Finland has included 23 species, eight species groups and one hybrid in the national list.
