Habitat
Wolverines primarily inhabit boreal forests, tundra, and mountainous regions in remote, wilderness areas. They prefer cold climates with snow cover for much of the year, found in North America, Europe, and Asia. These areas offer ample space for roaming and access to prey.
Diet
Wolverines are opportunistic omnivores that primarily eat carrion such as deer or moose remains, small mammals like rabbits and ground squirrels, and birds. They also consume berries, roots, and insects, often scavenging or hunting at dawn and dusk when they are most active. Their powerful jaws allow them to crush bones and access frozen food sources.
Behavior
Wolverines are solitary animals that maintain large territories, marking them with scent to avoid encounters with others. They are primarily nocturnal but can be active during the day, traveling long distances of up to 15-20 miles in search of food. Known for their aggressive and fearless nature, they defend food caches vigorously and are highly territorial, especially during mating season.
Hunting
Trapped to some extent but the fur has little commercial value other than for parkas in arctic regions, because it accumulates little or no frost. Considered a pest worldwide because of its habits of following traplines and eating trapped animals, of breaking into cabins and food caches and befouling the contents with its anal scent glands after eating its fill, and of preying on domestic reindeer. As a game animal, it usually is taken as a target of opportunity while hunting other species. Tracking by snow machine is an option in some areas. Only wolverines that have been hunted are eligible for the SCI Record Book.
Conservation Status
The IUCN classifies the wolverine as Least Concern globally, but some populations are vulnerable due to habitat fragmentation. Major threats include climate change, which reduces snow cover, and human activities like trapping and road development.
