Wolverines are wide-ranging carnivores threatened by trapping, climate change, and habitat fragmentation. Their welfare suffers from both direct human persecution and environmental change.
Trapped wolverines experience severe welfare harms. Leg-hold traps cause injuries, frostbite, and prolonged distress before the trapper returns — often 24-48 hours in remote areas. Wolverines are energetically demanding animals with high food requirements; food stress during poor prey years causes significant suffering. Climate change is reducing the persistent snow cover wolverines need for den construction and food preservation, forcing pregnant females to seek alternative, often suboptimal denning sites. Wolverines displaced by habitat loss must travel greater distances for food, increasing energy expenditure and the risk of mortality from human causes including road collisions, livestock conflict, and trapping. The welfare and conservation crises for wolverines are deeply intertwined.
