An invasive species is any organism (plant, animal, insect, disease, etc.) that has been introduced to an area outside of its native range, has a tendency to spread, and threatens the environmental, economic or social health of the area to which it has been introduced.
We move species around the world every day, both intentionally and unintentionally, through our social and economic activities, and naturally through environmental pathways. Invasive species tend to show up more around urban centres and transportation hubs.
