Wolverines are rare, wide-ranging carnivores facing threats from climate change and trapping. Their welfare and conservation needs illuminate the challenges of managing secretive predators.
Wolverine welfare concerns center on the mismatch between their vast spatial needs and the increasingly fragmented wilderness available to them. These solitary, wide-ranging animals evolved in intact northern wilderness; the reduction of connected wild landscape forces them into smaller ranges where prey may be insufficient. The welfare of individual wolverines trapped for fur is a specific concern - leghold and other traps cause injury and prolonged suffering to animals that may not be retrieved for days. Climate change represents a more diffuse but potentially catastrophic welfare threat: females who cannot find adequate persistent snowpack for denning lose their kits, representing reproductive loss as well as the welfare costs of failed breeding attempts.
