Population Status of the Wolves

After hunting nearly forced the gray wolf (Canis lupus) to extinction in North America, the species is currently present within the Great Lakes, Northern Rocky Mountains (NRM), California, and the Pacific Northwest (defenders.org). Worldwide, there are approximately 200,000-250,000 individuals. Within Canada and the U.S. there are over 65,000 individuals with more than 85% found in Canadian territories. The U.S. population is between 13,400-16,900 individuals who are concentrated in Minnesota and Alaska (San Diego Zoo Wildlife Alliance 2021). The U.S. Fish and Wildlife Service is currently monitoring five populations of gray wolf; two of these populations have been delisted due to recovery, while the others are currently under review (Fish and Wildlife Service). 

Additional populations of the gray wolf can be found in Europe (approximately 17,00 individuals) and Asia (approximately 81,500 individuals) (San Diego Zoo Wildlife Alliance 2021). Gray wolf populations located within the European Union (EU) have been designated as Least Concern but are still protected under the Ben Convention, EU Habitats Directive, and fully protected in Norway (San Diego Zoo Wildlife Alliance 2021).
