Take hom final Virginia Harris Part 1: A) Boyce and Waller predicted that 321 ± 49 bears could live in the Bitterroot ecosystem based on the Yellowstone ecosystem resource selection function models. This population estimate was based on using a resource selection function in which data from habitats, populations, and use similar to the study site is used to extrapolate a population estimate. In this case, data fromYellowstone and Swan Mountain was used. B)The most important limitations on population were food availability and human caused mortality. These were represented greenness, and high and low impact activity points. Spring results in bears being in the lower elevations, along with other seasonally related movements to various elevations. Resource facilitated movement also results in less human related resource selection in the Spring. C)One reason to conserve grizzly bears is the same as for almost any other species. They were here first, and it is highly likely that a lot of their population decrease is human related. We must
