Résumé

Largely due to influences related to dramatic human population growth, threats to many species are on the rise globally. An examination of mammals assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) determined the major threats facing terrestrial mammal populations in Canada. Significant threats were associated with habitat loss and overall mortality caused directly by humans. Carnivores and rodents differed substantially in mortality caused directly by humans and loss of food resources. Large mammals were more affected by climate change than small mammals.
