Wolverine, North Cascades.

Individual wolverines can be identified by their unique chest blaze. This female wolverine, affectionately known as Stella, has been captured on several of the projects camera traps.

Every wolverine has a uniquely identifiable chest blaze, allowing researchers to keep track of individual animals that show up at different research sites.

The Wolverine fire in the Lake Chelan watershed decimated fast stands of forest in the mountains here. Climate change is affecting how fires burn in the North Cascades. The impact of this on wolverines is currently unknown.

Smoke fills canyons on the western slope of the North Cascades during an unusual wildfire event in this rainforest clad landscape. Above treeline the grey ice and bare rock visible at the lower elevations of these North Cascades glaciers are a sign of glacier recession. Both of these are related to human caused climate change in the ecoregion which is predicted to reduce wolverine habitat significantly.

Glacial ice exposed at the very top of the Colonial glacier (upper left of this photo) suggests that this glacier no longer has an accumulation zone. Under current conditions, it is just a matter of time before the glacier disappears completeley--perhaps within the next several decades.

Mountains goats are often an important food item for wolverines. In the North Cascades wildlife managers are concerned their numbers may be declining.

Wolverines depend on locations where snow lingers into late spring, making natal dens in deep shaded valley bottoms or in high elevation talus fields.

White-tailed ptarmigan's in the Cascades were recently protected under the federal endangered species act due to habitat decline, mirroring concerns about the future of wolverines in these mountains.

Wolverines are a curious species that will inspect novel things in their environment such as our research and camera equipment.
