Conservation and Resource Assessments for the Tongass Land Management Plan Revision

Person, David K.; Kirchhoff, Matthew; Van Ballenberghe, Victor; Iverson, George C.; Grossman, Edward. 1996. The Alexander Archipelago wolf: a conservation assessment. Gen. Tech. Rep. PNW-GTR-384. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 42 p. (Shaw, Charles G., III, tech. coord.; Conservation and resource assessments for the Tongass land management plan revision). We summarized the scientific information available for the Alexander Archipelago wolf (Canis lupus ligoni) in the Tongass National Forest of southeast Alaska. Information concerning the morphology, distribution, taxonomy, genetics, and ecology of wolves are presented. Three issues for the conservation of wolves in southeast Alaska are discussed: loss of long-term carrying capacity for deer due primarily to extensive timber harvesting, increased mortality of wolves associated with improved human access from roads, and continued high levels of harvest of wolves by humans. Continued timber harvesting at current levels and by current methods will likely have adverse consequences for some segments of the wolf population. Although some short-term regulatory changes and the management of road access may need to be considered to keep wolf harvest at a sustainable level, the most important consideration is to maintain long-term carrying capacity for deer, the principal prey for most of the wolf population. A series of old-growth forest reserves may provide an effective strategy to increase the likelihood that wolves will persist where extensive timber harvesting has occurred, or is planned.
