The genus ''Arborimus'' is a group of voles found in western North America. The genus name means "tree mouse" in Latin. These animals live in forested areas and two species live in trees. They are small rodents with short ears and long legs. They are primarily herbivorous. Predators include owls and mustelids. Some sources include this genus with the heather voles, genus ''Phenacomys''. == Classification == The complete list of species is: *White-footed vole (''Arborimus albipes'') *Red tree vole (''Arborimus longicaudus'') *Sonoma tree vole (''Arborimus pomo'') Based on mitochondrial DNA, ''A. pomo'' and ''A. albipes'' are more closely related to one another than either are to ''A. longicaudus''.〔Bellinger, R., S. Haig, E. Forsman, and T. Mullins. 2005. Taxonomic relationships among ''Phenacomys'' voles endemic to western United States. Journal of Mammalogy, 86:201-210.〕〔Blois, J. L. and B. S. Arbogast. 2006. Conservation genetics of the Sonoma Tree Vole (''Arborimus pomo'') based on mitochondrial and amplified fragment length polymorphism markers.
