Timber wolves, also known as gray wolves, live in North America, Europe, Asia and parts of North Africa. Eastern timber wolves, considered a separate species, are found only in southeast Canada.
Associated with northern climates, timber wolves also live in warm regions. Livescience reports that timber wolves can survive a temperature range of negative 70 to 120 degrees Fahrenheit. They are considered native to the entire Northern Hemisphere, but they prefer to inhabit forested areas far away from human populations.
Timber wolves have long been considered a predator. They rarely approach humans but have been known to attack domestic animals. According to National Geographic, the species was once hunted to near extinction in the U.S. Although few wolves remain in Europe, they are still common in Alaska, Canada and Asia.
Timber wolves roam in packs with as many as 30 wolves, although 10 is a more typical number for packs. Each pack has a leader known as the alpha male. As a unit, they hunt, travel and protect their territory from outside threats, including other wolves not associated with the pack. Wolves are transitory and often travel several miles a day. As nocturnal animals, they conduct hunts at night and spend their days sleeping.
