Shiras moose forage selection in relation to browse availability in north-central Idaho
Forty-eight feeding site examinations from 1979 to 1981, consisting of 13 653 instances of use, described seasonal diets of Shiras moose (Alces alces shirasi) in north-central Idaho. Thirty-three of these sites were in mature, dense conifer stands. Pacific yew (Taxus brevifolia), menziesia (Mensiesi...
