Alaska records cluster in the boreal forest around Fairbanks and Denali National Park, and along the Yukon River valley, tracing the mossy, shaded conifer floor this vole depends on across the Interior.
It nests in root tangles and rotting logs and eats heavily on fungi year-round, including underground species most other forest animals never find. By moving through burrows and surface litter, it helps carry fungal spores to new ground, work that quietly supports the same trees whose roots those fungi partner with. In winter it tunnels beneath the snowpack, where the temperature stays far steadier than the open air above.
Alaska’s clearest records run October and November, but that doesn’t mean the vole goes quiet the rest of the year. It stays under snow and forest litter through the cold months, just harder for anyone to detect. The species remains widespread across the northern boreal belt as long as shade, moss, and rotting wood hold up on the forest floor.
