The wolverine is one of the most elusive large carnivores in North America, requiring vast wilderness territories and deep spring snowpack for denning, with welfare threatened by trapping, habitat loss, and climate change.
Wolverines face acute welfare threats from leghold trapping, which causes limb injuries, severe stress, and death by exposure or predation when animals are not checked frequently. The psychological complexity of wolverines, which show play behaviour and apparent frustration responses, suggests meaningful welfare capacity. Climate loss of spring snowpack threatens denning success, causing reproductive failure and potentially abandonment of kits. Habitat fragmentation creates dangerous dispersal routes across roads and developed land.
