This small rodent builds nests of small twigs and needles in the branches of its nest tree, and eats the tree’s needles by first stripping the resin ducts. Nests are constructed of branchlets, discarded resin ducts, and other materials, ultimately shaped into a sphere with interior tunnels. A comparison of historical data with current surveys strongly suggests that the North Oregon Coast population has declined significantly. The vole is an important prey for the threatened northern spotted owl and other owls (Forsman et al. This vole is endemic to western Oregon.

However, red tree voles now appear to be uncommon or absent in much of the North Coast Range and North Cascades of Oregon. The red tree voles that occur away from coastal areas will also inhabit Douglas fir. These effects are further exacerbated by the vole’s naturally narrow habitat requirements, low mobility, low reproductive potential, and low dispersal ability to move among limited habitat.

This species is an important dietary component for Northern Spotted Owl and other forest predators and is a species of concern given its dependence on mature forest and difficulty associated with monitoring population trends. Because of their exclusive diet of conifer needles, red tree voles are restricted to conifer forests. However, red tree voles in a portion of the North Coast Range are associated with Sitka spruce and western hemlock forests. Without protections, most of the private and state lands in this area are being heavily managed to maximize timber production — causing dramatic declines in the North Coast red tree vole.
