What is cited as the primary threat to wolverine habitat resulting from rising temperatures?
Answer
Reduced snow persistence
The long-term survival of the wolverine is intrinsically linked to climatic conditions, specifically the presence of snow. Defenders of Wildlife highlight that the most significant threat arising from rising temperatures is the reduction in snow persistence. If locations lose their reliable spring snow cover—which is essential for late-season denning—they may cease to function as meaningful habitat for the species, even if the elevation is otherwise suitable.
