Douglas-fir seedlings, Pseudotsuga menziesii (Mirb.) Franco, which have been planted on Crown lands under the jurisdiction of the B. C. Forest Service following logging have in many cases been damaged and severely limited in growth due to browsing by blacktail deer, Odocoileus hemionus columbianus (Richardson). Among the most serious of problem areas is the mid-west coast of Vancouver Island and its smaller neighbouring islands. The most severely damaged plantations in this area are found on Union and Nootka Islands and in the Amai Creek and Kaouk River drainages (M. Wareing, personal communication), where plantations up to eleven years of age exhibit negligible growth since planting (see Map I). Economic losses'due to delayed establishment of healthy forest stands are of considerable concern to the Forest Service and to industry, and means of preventing browsing damage are therefore a valuable tool in forest management. This study attempts to evaluate the biological background to the browsing problem in two areas considered to represent typical examples of situations which will be found elsewhere, and to list and evaluate in terms of probable effectiveness alternative remedies for each situation. The effectiveness of each alternative is rated only on the basis of a solution to the browsing problem. No consideration has been given to the welfare of the deer population.
