Invasive species

Invasive alien species are living organisms spread by human action. Some are introduced intentionally for useful purposes, while others may be transported to Finland unintentionally, notably in packaging materials or ships' ballast water. Some species are able to thrive in their new habitats, where they may hinder the survival of native species, spread diseases or cause significant changes in the structures of ecosystems. Invasive alien species are considered to be the second most serious global threat to biodiversity, after habitat loss.
