Since it was first discovered in 1890, the red tree vole has remained a mysterious resident of the forests of western Oregon. Most people don’t even know they exist, and even those who study them often have a difficult time finding them. Although they appear to be a fairly common resident in old forests in western Oregon, there is concern that their numbers may be declining as a result of habitat loss, especially in northwest Oregon, where there is little federal land and very little old forest. Because of concerns about habitat loss and evidence of low population numbers in some areas, the US Fish and Wildlife Service recently concluded that the red tree vole warrants listing as a threatened species in parts of its range. In this talk Eric will describe what we know about the distribution and population status of the tree vole and describe the behavior of the species based on recent studies in which video cameras were used to observe tree voles at night.
