Decision model simulation of the reintroduction of bull trout in the upper Lake Chelan basin, Washington
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 and 70 years after reintroduction). Here, in the data tables, we provide results from a one-way sensitivity analyses and global sensitivity analyses as well as the potential effect of dispersal on simulated bull trout populations.
