This report summarizes information gathered to date in the coastal grizzly bear project, outlines proposed management products, and presents the working plan for 1986. Year 4 1985 marked the end of the first phase of the study, the intensive field work in the lower Kimsquit River valley. Results of monitoring grizzly bear movements, home range, and habitat, cover, and food selection are presented and discussed in terms of the potential impacts of logging. Four-year home ranges of two adult female grizzly bears were 30.4 (N-236) and 25.3 (N=241) km2 using the reduced minimum convex polygon method. Two adult female grizzlies spent approximately 30% of their active season (1982-1985) in coniferous forests, 40% in floodplain seral habitats, 20% in high elevation units and 2% in logged areas. Results of testing the accuracy and error estimation of the ground telemetry system are given. Of the 85% of tests that gave closures, only 20% were actually located within the assigned error polygon.
