Invasive Species

A species is considered invasive if it has been introduced into the environment where it is not native and that has since become a nuisance through rapid spread, often to the detriment of native species.  Invasive species arrived in Ontario generally through people who moved here and brought them from their native country.  Information on six particular invasive species can be found under the Three Invasive Species Article and Beware of Invasive Plants.
