North America:
* Canada: Widely distributed across the country, particularly in the boreal forests, tundra, and mountainous regions.
* United States: Primarily found in the northern and western states, including Alaska, Minnesota, Montana, Wyoming, Idaho, and Oregon. Their range is expanding in some areas as they are reintroduced.
* Mexico: A small, isolated population exists in the northern Mexican states.
Eurasia:
* Europe: Found in Scandinavian countries, Eastern Europe, and parts of Central Europe. Their range has been expanding in recent decades due to reintroduction efforts.
* Russia: Large populations exist across Siberia and the European part of Russia.
* Asia: Found in parts of China, Mongolia, and other Central Asian countries.
Key factors influencing their distribution:
* Suitable habitat: Grey wolves prefer large, undisturbed areas with abundant prey, such as deer, elk, and moose.
* Presence of prey: Their distribution is heavily influenced by the availability of their main food sources.
* Human activity: Human encroachment, hunting, and habitat fragmentation can impact wolf populations.
Note: The distribution of grey wolves is constantly changing as they expand their range in some areas and face threats in others.
