Woodland vole records in Pennsylvania come entirely from GBIF specimen and trapping data, with not one iNaturalist photograph in the mix, which tracks with an animal that spends nearly its whole life tunneling under leaf litter and rarely surfaces where a person could see it. Sightings turn up in every season but peak sharply in November, a spike that likely reflects when small-mammal surveys run rather than any true rise in activity underground.
NatureServe rates the woodland vole Secure across Pennsylvania, S5, and its occasional ranking among Pennsylvania mammals has more to do with how hard the species is to detect than with any real rarity. Reports concentrate around Allegheny National Forest, Delaware Water Gap, and Ricketts Glen State Park, forested sites with the loose, litter-covered soil this vole needs for its shallow burrow systems.
