A border vole
This is a compact vole about 4 to 6 inches long including a short tail, yellowish-brown above and grayish below, with notably long claws on the forefeet for digging. The name comes from its Canadian haunts, where it feeds heavily on heather and other low shrubs. South of the border it reaches only the northernmost tier of the lower 48, and in the United States Minnesota holds the confirmed records.
For most of the twentieth century this animal was considered the same species as the western heather vole of the Rockies and Pacific ranges. Detailed study split them, leaving the eastern heather vole with a huge Canadian range and only a thin slice of US territory. Telling the two apart by sight is not realistic; the boundary does the work.
Forest floor, northern style
Heather voles live in cool coniferous and mixed forest, using runways through ground cover and stocking small caches of cut vegetation for winter. They are active year-round under the snow, and their middens of clipped stems and droppings are often the first sign of their presence. In Minnesota that means the bog edges, spruce-tamarack stands, and brushy cuts of the northern counties.
The record set is correspondingly thin, a small handful of documented occurrences. That reflects both genuine scarcity this far south and the difficulty of separating this vole from the red-backed voles and other small brown neighbors without a specimen in hand.
What a handful of records means
The IUCN rates the eastern heather vole Least Concern across its full range, which is secure and extensive in Canada. The US question is narrower: a species at the extreme southern edge of its distribution, where small populations are naturally scattered and vulnerable to local change.
Minnesota’s records, few as they are, mark the southern rim of a northern animal. Records at a range edge always look sparse, and some of that sparsity is real rarity while some is detection difficulty. Either way, each confirmed occurrence helps pin down where the species actually reaches, and the state’s north-woods surveys keep adding to that small but important file.
