Abstract: | The effects of sex, ageclass, and season on habitats and elevations selected by 56 radiocollared grizzly between 1979 and 1995 in the Flathead River drainage of southeastern British Columbia and the adjacent portion of Montana were evaluated using compositional analyses. Two habitat selection strategies were apparent in the population: Mountain resident bears selected avalanche chutes at higher elevations during spring, while elevational migrating bears moved to low elevations and selected riparian habitats. During summer, both groups of bears showed selection for areas that had been burned by wildfire 50-70 yr previously. In autumn, riparian was the highest ranked habitat followed by forest and open forest. Regenerating cut-blocks and rock outcrops consistently ranked lowest. Results of this southern grizzly bear study differ from others in that bears were free to select habitats in both mountains and the wide valley and they showed strong selection for some low elevation habitats. |
