    Description

    We describe occupancy of arboreal nests of tree voles (Arborintus spp.) by four amphibian species in western Oregon and northern California, including clouded salamanders (Aneides ferreus), arboreal salamanders (Aneides lugubris), Pacific tree frogs (Pseudacris regilla), and a California giant salamander (Dicamptodon ensatus). These observations suggest that occupancy of the canopy of Douglas-fir (Pseudotsuga menziesii) forests by arboreal amphibians may be a more common phenomenon than is generally known. We suggest that salamanders and Pacific tree frogs may be attracted to occupied vole nests because they support large populations of invertebrate prey and provide a damp microenvironment. Tree voles may benefit from the presence of amphibians in their nests because the amphibians feed on mites and other arthropods that commonly infest vole nests. We suggest that more detailed studies are needed to determine the extent of arboreal activity by salamanders in Douglas-fir forests.
