Deep, workable soil links Pennsylvania’s hairy-tailed mole records across upland forest, moist ravines, wooded slopes, and old fields. Soil depth and moisture at Allegheny National Forest, Ricketts Glen, and Delaware Water Gap are more informative than the park names themselves for an animal that remains underground.
Records jump in April, persist through summer, and rise again in October. Rain, thaw, or ground disturbance can expose tunnels or animals, so surface discoveries do not indicate how many moles are below.
