Description

Grizzly bear population inventory work has been underway in various population units along the eastern slopes of Alberta. As of the time of the preparation of this report two population units have not been inventoried, the Swan Hills and the Alberta North units. In order to provide a science based estimate of possible grizzly bear population size in the Swan Hills unit we utilized existing data sets from previous DNA inventory work to provide estimates for the purpose of a species status review. We used an objective, multi-scale approach to estimating occupancy-habitat associations based on DNA hair snag information and predicted (extrapolated) occupancy to similar habitats in the Swan Hills grizzly bear management unit.
