Abstract

A repellent evaluation process used by the U.S. Fish and Wildlife Service in a research program directed at reducing browsing damage to regenerating Douglas-fir (Pseudotsuga menziesii) by black-tailed deer (Odocoileus hemionus columbianus) in the Pacific Northwest is reviewed. Several methods of repellent testing to control deer damage to commercially valuable trees are being used in the United States. Our procedures to assess deer damage and efficacy of candidate repellents could be used in most of these evaluations to provide uniform data for comparisons of materials and aid in registration of deer repellents needed by land managers.
