Endangered Plants in Canada

A species is endangered if there are threats to its survival. Plants are put at risk for several reasons, including: climate change and the loss of natural habitat to cities, agriculture and industry. In Canada, these activities threaten entire natural ecosystems, such as older forests and Prairie grasslands. As of 2021, 250 plant species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, four are extirpated and one is extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the bent spike-rush (Eleocharis geniculate) is included on the list of at risk plant species twice, as there are two different populations, one in British Columbia and one in Ontario, facing different threats to their survival.

Endangered Animals in Canada

Many animals in Canada face the risk of extinction. Animals are put at risk for several reasons, including: climate change, the loss of forest and grassland to cities and agriculture, hunting, fishing, and the pollution of lakes and rivers. As of 2021, 554 animal species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, 18 are extirpated and 18 extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the beluga whale (Delphinapterus leucas) is included in the list of at risk animal species six times, as there are six different populations facing different threats to their survival.
