| Summary: | This study was initiated to obtain information on the ecology of the northern interior grizzly (Ursus arctos), with the main objective of obtaining detailed data from a self-regulating population on a study area in the interior mountains of the Yukon Territory. The study area was the Kluane Game Sanctuary, and the study ran from July 1964 to September 1972. Population size was determined by total enumeration of all grizzlies in the study area. Ecological information was collected from observation of free-roaming marked bears. Specimen material from 320 grizzlies from the range of the northern interior ecotype was examined to determine the sex and age distribution of the population. Final age was determined from analysis of teeth, and a technique to determine age from skull measurements was refined. Grizzly bear harvest data from the Yukon were collated and analyzed to establish a base with which to compare and appraise subsequent harvest patterns. Some ideas regarding grizzly management in general are also discussed. |
