South Carolina’s occurrence databases hold 439 records for the American beaver, the densest cluster of any mammal in this dataset, drawn mostly from iNaturalist and backed by a solid run of GBIF data. That tally tracks where people have logged dams, lodges, and gnawed stumps. It doesn’t count how many beavers actually work the state’s waterways.
From Blue Ridge creeks to Lowcountry blackwater
Records turn up in three very different corners of the state: the fast, rocky streams below Table Rock State Park in the Blue Ridge escarpment, the tannin-dark river swamp of Congaree National Park in the Midlands, and the tidal-fed creeks of Francis Marion National Forest out on the coastal plain. A beaver only needs water deep enough to hide a den entrance year round and woody plants close to the bank, and South Carolina supplies both from the mountains down to the coast.
A vegetarian that reshapes its own creek
Beavers gnaw bark and the soft cambium beneath it from sweetgum, willow, and river birch, then haul the cut branches into an underwater pile that becomes a winter larder. That felling opens the canopy along a stretch of bank and lets the same sun-loving saplings resprout, feeding the colony again the following year. Records climb every spring, matching the months when two-year-olds strike out from their home pond to build somewhere new, and fresh dams and pale, pencil-pointed stumps are at their easiest to spot and report.
Status in South Carolina
NatureServe ranks the American beaver S5, secure, and the species is native across the state. It’s the most dependable wetland engineer South Carolina has, holding water and building habitat everywhere from Blue Ridge headwaters to coastal blackwater rivers.
