The Chelan mule deer herd occupies a mix of private and public lands from the Columbia River to the crest of the Cascade Range in central Washington. U.S. Highway 2, northwest of Wenatchee, Washington, serves as the southern boundary for this herd and Lake Chelan bounds the northern edge. The high-use winter range includes the southeastern shore of Lake Chelan, the breaks of the Columbia River, the lower Entiat River drainage, and the foothills east of Cashmere, Washington. In the spring, migratory individuals travel northwest into the Entiat and Chelan Mountains to their summer ranges, such as regional Wilderness areas. A small sample of Chelan mule deer was captured near the Swakane Wildlife Area in January 2020 (n = 19 adult females). Thus far, most individuals captured have been migratory, although some individuals reside year-round in the foothills east of Cashmere and along the Columbia River. On the winter range, residential development and disturbance from human recreation continue to be a concern. Semipermeable barriers to migration include U.S. Highway 97A, which overlaps the winter range along the Columbia River, and U.S. Highway 2, which bisects several individual migration routes. These mapping layers show the _location of the migration corridors for Mule Deer (Odocoileus hemionus) in the Chelan population in Washington. They were developed from 40 migration sequences collected from a sample size of 11 animals comprising GPS locations collected every 4 hours.

The feasibility of a potential bull trout (Salvelinus confluentus) reintroduction was simulated across 12 streams and river segments in the upper Lake Chelan basin using a population matrix model. The model considered habitat availability, life history expression, and assumptions regarding constraints on potential bull trout populations. Details of the simulation framework are described in Benjamin et al., 2024 (submitted publication). Scenarios for model simulations included life stage, number of individuals, and years following potential reintroduction. We considered, four life stages of bull trout, eggs, juveniles, subadults and adults. Each life stage has three options for the numbers of individuals reintroduced. For eggs, it was the addition of 5,000, 10,000 and 20,000 individuals; for juveniles, 200, 500, and 2000 individuals; and for subadults and adults, 30, 60 and 100 individuals. Simulated numbers of adult bull trout are provided over 5 time periods (5,10, 30, 50 a ...
