Southern red-backed voles turn up in 318 mapped Maine records, most of them logged from mid-summer into fall. That seasonal shape says more about when small-mammal surveys run in the state’s forests than about any real swing in vole activity itself.
Downed wood is the real habitat
This vole rarely strays far from a fallen log or a patch of deep moss. Maine’s North Woods and the Western Maine Mountains hold the cool, moist, conifer-heavy forest this species needs, and just as important, they hold plenty of the decaying, coarse woody debris a red-backed vole uses for cover and runways. Cleared or heavily thinned forest, with the fallen wood removed, offers far less of what this species actually needs to get by.
An underground fungus-eater that feeds the forest back
Much of a red-backed vole’s diet is fungus, including underground truffle-like fungi it digs up and eats, alongside seeds, berries, and insects. That habit isn’t just a quirk of the animal’s diet. Eating and moving spreads the spores of fungi that form partnerships with tree roots, helping conifers pull nutrients from Maine’s often thin, acidic forest soil. A vole tunneling through a mossy log in the North Woods is doing more for the forest around it than just staying fed.
Status in Maine
NatureServe ranks the southern red-backed vole S5, secure, and it’s native to Maine. Its dependence on downed wood and intact forest floor makes it a useful stand-in for how undisturbed a patch of Maine woods really is.
