Abstract
Animal translocations are frequently used in conservation programs to assist the recovery of endangered species. Understanding the factors contributing to extreme post-release movements is crucial for improving translocation efficacy. We examined post-release movement phases and habitat selection of translocated red squirrels (Tamiasciurus fremonti fremonti) in the White Mts of Arizona. Post-release movements of translocated red squirrels represent at least two different behavioral phases characterized by differences in movement patterns and the scale of selection for environmental features. During the first phase (“exploratory phase”), squirrels made long rapid movements and selected areas with taller trees and valley bottoms basing their landscape evaluation at relatively broad spatial scales (i.e., 500-600 m). In contrast, during the second behavioral phase (‘settlement phase’), squirrels seemed to behave like resident squirrels by displaying shorter movements within a smaller area, caching food, and defending their middens. Importantly, translocated squirrels also selected areas with fewer resident conspecifics.
