Conservation Status: Least Concern.

The Eastern Heather Vole has a wide distribution across Canada. Its population is thought to be very sparse, but this could be because so few are trapped. Remains of the Eastern Heather Vole in owl pellets and marten feces indicate higher densities than trapping records suggest. Other predators include hawks and weasels. Eastern Heather Voles often pile food near their burrows, probably gathering it at night to eat the following day. They do not hibernate, and it is not clear whether or not they store food supplies for winter.

Also known as:
