A mother wolverine and her kit play at the edge of a subalpine forest in the Pacific Northwest. Wolverines den%2C hunt and scavenge for carcasses in the snowpack on the sides of mountains. Perhaps 300 wolverines%2C or less%2C are left in all of the Lower 48. Climate change represents a major threat to habitat%2C but so%2C too%2C researchers say%2C is disturbance by recreationists in mountain environment. People displace wolverines from habitat they need to survive. Photo courtesy NPS%252FCascades Carnivore Project
