The red tree vole is a small rodent that lives in trees in coniferous forests in the west of North America. It almost never descends to the ground and feeds on needles.
The red tree vole differs from other voles by living high in trees and feeding on needles. It is important for the forest as food for birds of prey and as part of nutrient cycling in old coniferous forests.
