Species at Risk and Invasive Species

Species at Risk – The purposes of the Species at Risk Act (SARA) are to prevent Canadian indigenous species, subspecies, and distinct populations from becoming extirpated or extinct, to provide for the recovery of endangered or threatened species, and encourage the management of other species to prevent them from becoming at risk.  The Christie Lake Association, Inc. strives to keep the Lake community informed on several invasive species that may impact Christie Lake.  Species at Risk in Kemptville District – pdf 848kB

Endangered – A species is classified as endangered if it lives in the wild in Ontario but is facing imminent extinction or extirpation (if it lives somewhere in the world, and it at one time lived in the wild in Ontario, but no longer lives in the wild in Ontario).

Threatened – A species is classified as threatened if it lives in the wild in Ontario, is not endangered, but is likely to become endangered if steps are not taken to address factors threatening it.


Special Concern –  A species is classified as special concern if it lives in the wild in Ontario, is not endangered or threatened, but may become threatened or endangered due to a combination of biological characteristics and identified threats.

Invasive SpeciesInvasive species are plants, animals, aquatic life and micro-organisms that out-compete native species when introduced outside of their natural environment and threaten Canada’s ecosystems, economy and society.
