Black bear resource selection in the northeast Cascades, Washington

We examined resource selection of black bears in the northeast Cascades of Washington at two spatial scales. Specifically, we compared habitats selected for within home ranges to those available in the study area, and habitats selected for versus those available within home ranges. Compositional ana...

description We examined resource selection of black bears in the northeast Cascades of Washington at two spatial scales. Specifically, we compared habitats selected for within home ranges to those available in the study area, and habitats selected for versus those available within home ranges. Compositional analysis showed selection of similar habitats at each spatial scale, with some differences. In the dry climate of the eastern Cascades, black bears appeared to locate home ranges within habitats that would provide abundant food resources, such as riparian and deciduous forests, meadows and shrubfields. Once established in a home range, black bears selected for a mosaic of habitat types that provided security cover in proximity to food resources, such as riparian and deciduous forests, other forest types and meadows.
