The complete county distribution, spread across 3 West Virginia counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

West Virginia’s 12 rock vole records come from the highest, coolest corner of the state. Pendleton and Randolph counties, which share the Spruce Knob and Dolly Sods high country of the Monongahela National Forest, hold 11 of them, and Webster County adds the twelfth. Here the rock vole is a mountain relict, holding on in mossy boulder fields and red spruce slopes far south of its main northern range.

Ice Age leftovers on the high ridges

South of Pennsylvania, rock voles survive in scattered high-elevation pockets, cool refuges left over from a colder climate. Cheat Wildlife Management Area, with 5 records, and the Blackwater Falls country sit in exactly that zone: rocky, spruce-shaded, and wet. Watoga State Park rounds out the suggested ground farther south. Each pocket is isolated from the next, which makes every occupied ridge matter and every new record genuinely informative.

A June flush

Half of West Virginia’s records landed in June, the month when survey crews work the high country and the voles’ runways through the moss are freshly busy after snowmelt. The animals themselves stay active all year beneath the snowpack; the calendar says more about access than activity.

Status in West Virginia

NatureServe ranks the rock vole S2, imperiled, in West Virginia, a sharper grade than it earns anywhere farther north. Native, patchy, and tied to a habitat that warming winters won’t improve, it’s one of the state’s more quietly consequential small mammals. Thin records don’t prove decline, but at the southern edge of a range they deserve attention rather than reassurance.
