The complete county distribution, spread across 9 Massachusetts counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Massachusetts’s occurrence tallies for the woodland vole hold 69 records, most of them clustered in spring, tracing three separate parts of the state rather than one core range.

An orchard-country connection in the valley

The woodland vole spends nearly its whole life underground, tunneling through loose, well-drained soil beneath leaf litter, old fields, and orchard rows, and that habit lines up with the Connecticut River Valley’s long history as Massachusetts’s fruit-growing country. Farther east, the forested hills of the Worcester Plateau and the wooded uplands behind the coastal plain’s marshes offer the same loose woodland-floor soil, minus the orchards.

A vole that gnaws roots, not grass

Unlike the meadow voles that graze on grass in open fields, the woodland vole feeds mostly on roots, bulbs, tubers, and bark from below ground, which is also why orchard growers in the valley have long dealt with it as a root-gnawing nuisance around fruit trees. Records here spike in May, when spring breeding activity brings more voles closer to the surface, then rise again in early fall.

Status in Massachusetts

NatureServe ranks the woodland vole S5, secure, and it’s native to Massachusetts. Its scattered, modest record fits a species that spends nearly all its life out of sight underground, not one under any particular strain.
