Studies of forage preferences of black-tailed deer (Odocoileus hemionus columbianus) were conducted during the winters of 1962 and 1963 in a 3-acre enclosure in the Tillamook Burn of northwest Oregon. Two deer were allowed to forage on native vegetation and planted Douglas-fir (Pseudotsuga menziesii) seedlings while periodic inspections were made of availability and use of trailing blackberry (Rubus ursinus) leaves, twigs of woody species, and the conifer seedlings. Blackberry leaves were the most highly preferred forage during the trial periods. Leaves of salal (Gaultheria shallon) ranked high but plants were relatively scarce in the enclosure. Red huckleberry (Vaccinium parvifolium) and cascara (Rhamnus purshiana) were preferred woody plants but other common species including red alder (Alnus rubra), hazel (Corylus californica), and vine maple (Acer circinatum) were utilized only when leafy forage was unavailable. Douglas fir ranked higher in preference than most common woody plants. Winter-active herbaceous forage was qualitatively determined to be highly preferred winter and early spring food. Douglas-fir and woody plant browsing appeared to be closely related to weather during the winter.
