Wolverines are powerful, wide-ranging mustelids whose survival depends on deep, persistent snowpack for denning. Climate change is reducing suitable habitat faster than most species can adapt.
Wolverine welfare concerns are primarily at the population level, but individual harms from trapping bycatch are significant. Wolverines caught in leg-hold traps or snares may suffer for extended periods before being discovered, and many injuries require euthanasia. Climate-driven habitat loss creates a slower but pervasive welfare harm — individuals that cannot find sufficient prey, mates, or den sites experience chronic nutritional and reproductive stress. Connectivity between habitat patches is essential; wolverines that disperse across fragmented landscapes face road-crossing mortality and isolation from breeding populations. Conservation measures that maintain snowpack refugia and reduce trapping bycatch address both individual and population welfare needs.
