Grizzly bear use of avalanche chutes in the Columbia Mountains, British Columbia ...
I examined spring season use of avalanche chutes by grizzly bears (Ursus arctos L.) in the Columbia Mountains, southeastern British Columbia. Sixty radio-collared grizzly bears were monitored between 1994 and 1998. The frequency of avalanche chute use, the selection of general habitat characteristic...
