Movements of northern flying squirrels in different-aged forest stands of western Oregon

Article Abstract:

The home ranges and movements of northern flying squirrels in old-growth and second-growth coniferous forest stands were investigated to determine differences in habitat. To this end, 39 samples from the Cascade Mountains of central Oregon were livetrapped and radiotagged in the summer and fall of 1991-1992. It was found that male northern flying squirrels had larger mean home range sizes than females. No association was identified between distances moved and stand type or sex. These findings suggest that abundance and movements of squirrels have no effect on the preferential selection of old-growth forests by northern spotted owls.
