When the park was expanded into the present Denali National Park and Preserve in 1980, it incorporated the territories of
many more wolf packs. A complete survey of the park’s wolf population was undertaken in 1985 (Dalle-Molle and Van Horn 1985), and in the course of that aerial survey, the remains of eight wolves that had been poached from aircraft were found in the park. Concern over the extent of wolf poaching led the NPS to begin extensive wolf research in 1986, using radio collars to keep track of the packs (Mech et al. 1998). With more than a dozen wolf packs roaming over many thousands of square miles, radio collars have provided the means to study wolves throughout the park, and throughout the year.
