Fossil finds have helped document shifts in the geographic distribution of the Woodland Vole over the centuries. During the Pleistocene, when glaciers covered much of North America, this species ranged well into Texas and northern Mexico. As the climate warmed and the Southwest got drier, Woodland Voles, which prefer habitats with a thick leaf layer or dense grassy patches, became concentrated in the eastern United States. Other small mammals found in the same habitats as Woodland Voles include Jumping Mice, White-footed Mice, Deermice, Red-backed Voles, Prairie Voles, Meadow Voles, Smoky Shrews, and Short-tailed Shrews. Hairy-tailed Moles frequently share their burrow systems.
