West Virginia’s eastern harvest mouse record is a historical document. Nine of the state’s ten records come from Greenbrier County, with a lone record from Cabell County at the western edge, and NatureServe now ranks the species as possibly extirpated from the state (SH).
What happened is the familiar story of grassland loss at the edge of a range. West Virginia was never the heart of harvest mouse country. The species reached its northern limits here in weedy fields and meadow edges, habitat that faded as small farms grew back into forest or gave way to more intensive use. A mouse that needs standing grass year-round has little margin in a state trending toward trees.
The records that remain still do useful work. They pin down where the mouse was documented, the Greenbrier valley above all, and that gives any future survey a place to start looking. Edge-of-range species blink out quietly, and sometimes they turn back up quietly too, when someone finally traps the right field. Until a fresh record appears, West Virginia’s harvest mouse exists mainly as these few entries, a reminder that a sparse record can mark a real loss and not just a lack of looking.
