The Allegheny woodrat isn’t the pest species its name suggests. It’s a native packrat of broken rock, cliffs, and boulder piles across the Appalachians, hauling food and found objects back to sheltered crevices. Pennsylvania’s 25 records are almost entirely GBIF entries rather than iNaturalist photos, the kind of split that usually points to specimen or trapping surveys rather than casual sightings, which fits an animal that dens deep in rock and rarely poses for a camera.

NatureServe ranks it S2, imperiled in Pennsylvania, matching a rangewide decline tied to disease and shrinking forest mast. Records turn up across the year with no single strong peak, spread from spring through fall. The listed sightings cluster near Pymatuning, Presque Isle, and Delaware Water Gap, places with heavy visitor traffic rather than the rocky slopes this species actually needs, a reminder that report location tracks where people look as much as where woodrats live.
