South Carolina’s occurrence databases hold 107 records for the southern flying squirrel, all from GBIF specimen and survey data rather than iNaturalist, which fits a strictly nocturnal animal that most people never see alive.
Canopy connectivity, from the Sandhills to Congaree’s giants
Records concentrate at Sumter National Forest, Carolina Sandhills National Wildlife Refuge, and Congaree National Park, three sites that look different on the surface but share what this squirrel actually needs: a connected canopy to glide through and old cavity trees to den in. Carolina Sandhills sits on the fall line, a longleaf pine and turkey oak landscape where the squirrel depends on scattered hardwood pockets for cavities. Congaree’s old-growth bottomland, with some of the tallest trees in the eastern United States, offers the same thing at a much larger scale.
A glider that never actually flies
A southern flying squirrel doesn’t fly so much as fall in a controlled line, stretching a loose skin fold between its wrists and ankles to glide a good distance between trees before it flares and lands. That trick depends entirely on canopy gaps small enough to clear, which is why records disappear fast once a forest gets fragmented into isolated patches, even where individual trees still hold plenty of cavities.
Status in South Carolina
NatureServe ranks the southern flying squirrel S4, apparently secure, and it’s native to South Carolina. Its steadiest South Carolina records sit inside protected, structurally intact forest, Congaree’s old growth and the Sandhills’ longleaf remnants among them, ground where the connected canopy this species depends on hasn’t been broken up.
