Wolverines depend on persistent spring snowpack for denning and kit survival — as climate warming reduces snowpack, wolverine reproductive success is declining with significant welfare implications.
Female wolverines unable to find adequate snow for denning face reproductive failure and kit mortality — a welfare harm with a direct climate mechanism. Kits born in inadequate dens that lose snow cover before weaning are exposed to cold stress and predation. The individual welfare harm — the loss of a litter, the energy expenditure of a failed reproductive attempt — is real and measurable. The welfare case for wolverine conservation is inseparable from the case for climate action.
