9 | P a g e Southern Cascades, during the CWMP 2013 monitoring season we focused our efforts on responding to anecdotal reports of wolf activity south of I-90. WOLVERINE MONITORING The largest terrestrial members of the weasel family, wolverines are one of the rarest carnivores in North America. 7 Wolverines prefer alpine environments where snow packs persist well into summer months. In addition to living in these difficult environments where food is scarce, wolverines are extremely mobile carnivores with home ranges between 100 km² to upwards of 900 km²; this means they typically live in low densities across large landscapes. 8 After almost complete eradication in the 1900s from the lower 48 states, wolverines have begun a comeback to places such as the North Cascades; and since 2005, state researchers have identified a dozen individual wolverines. But much is still unknown about these rare and elusive species, and that's where the Citizen Wildlife Monitoring Project comes in. Though currently unprotected, wolverines are candidates for endangered status under the Endangered Species Act at both the federal and state levels. In 2014, the USFWS is planning to publish their final ruling on the listing status for wolverine nationwide. 9 Conservation Northwest and other organizations are pushing decision makers to create state and federal safeguards for wolverines as they recover across Washington and the lower 48 states. Through CWMP monitoring activities, Conservation Northwest will help shape recovery and critical habitat plans for Washington, inform land management, and build upon ongoing research in the Cascades. Our goals for wolverine monitoring in 2013 were to 1) help the Entiat Ranger District of the Okanogan-Wenatchee National Forest monitor wolverines' presence in the Entiat Valley in the Glacier Peak Wilderness in the North Cascades, with a specific interest in documenting Sasha, a potentially denning and reproducing female wolverine, 2) document the presence of wolverines in the Central and Southern Cascades; and 3) collect genetic data through hair samples to help identify individual wolverines documented. In 2013, our wolverine monitoring continued in the Chiwaukum and Bootjack Mountains where our remote cameras have documented four individual wolverines to date. To ensure that our efforts add to existing research, we focus on areas that lie outside of the current study area established by the 7 Keith B. Aubry, Kevin S. Mckelvey, and Jeffrey P.
