"Winter recreational use, particularly snowmobile and heli-skiing, may be having potentially severe localized habitat impacts on wolverines. While the impact on populations due to removal of critical denning habitats is more obvious, these recreational uses may be placing additional impacts on wolverine populations by removing foraging habitats as well. Management of snowmobile and heli-skiing is warranted in areas with significant amounts of potential denning habitat, and should include access restrictions during the denning period (February – April)."
