These animals are similar in appearance to the meadow vole. Square habitat patches were not significantly different from rectangular patches in meadow vole density. It is similar in structure to that of the meadow vole, but with different proportions. Patterns of mortality apparently vary among meadow vole populations. Predator numbers are positively associated with meadow vole abundance. The seeds are eaten by small rodents, such as the eastern chipmunk and meadow vole. Voles include the prairie vole, woodland vole and the meadow vole. Meadow vole habitat devoid of tree cover and grasses dominated the herb layer. Compared to the meadow vole, prairie voles prefer to inhabit drier areas. Predators, particularly raptors, should be protected to keep meadow vole populations in check. Wildlife inhabiting the park include white-tailed deer, coyote, and meadow vole. Slash burning did not appear to affect meadow vole numbers about 1.5 years after treatment. Other mammals were prairie deer mice, common raccoons, meadow vole, and meadow jumping mouse. Optimal meadow vole habitat consists of moist, dense grassland with substantial amounts of plant litter. The meadow vole is active year-round, usually at night.
