WINTER HABITAT SELECTION BY MOOSE IN NORTHERN BRITISH COLUMBIA
This study reports a 3-year field investigation of the relationships between moose (Alces alces andersoni) and their winter habitat in the Liard River valley in northern British Columbia. Sixteen browse species accounted for 97 percent of all browse utilization by moose, with willows alone contribut...
