Historically, wolverines ranged south from Canada and Alaska, through the mountainous regions of the West to California, Utah, and Colorado. Today, healthy populations of wolverines inhabit remote, high-elevation areas of the Northern Cascades in Washington, and the northern Rocky Mountains in Idaho, Montana, and Wyoming. It is estimated there are between 250-300 wolverines in the contiguous United States today. Current climate change projections indicate that wolverines could lose up to 63% of their snowy habitat in the lower-48 by the year 2085. Colorado’s Rocky Mountains are likely to retain much of their spring snowpack, because of their high elevation, which could provide an important refuge for wolverines in the West.
