Wolverines are among North America's most elusive and wide-ranging carnivores, with their welfare tied to vast territories, persistent snowpack for denning, and freedom from the trapping that still claims thousands annually.
Wolverines face a dual welfare crisis: individual suffering from trapping, and population-level existential threat from climate change. Trapped wolverines experience acute pain from the trap mechanism, progressive injury as they struggle to escape, and the prolonged stress and suffering of confinement in extreme cold until the trapper arrives. Climate change threatens wolverines not through sudden events but through a slow erosion of the spring snowpack that makes successful breeding possible - a landscape-level reduction in reproductive success that represents a form of chronic population-wide welfare harm. As climate change accelerates, more individual wolverines will experience breeding failures and the stress of failed reproductive investment.
