The patch-nosed salamander (Urspelerpes brucei) is a geographically restricted plethodontid salamander known only from approximately 20 km2 in the Tugaloo Mosaic of Georgia and South Carolina. All of the 17 documented localities are in first- and second-order streams in or near the Brevard Fault Zone and Tugaloo River. Here, we use environmental DNA surveys to test for the presence of the patch-nosed salamander in two regions of potential occupancy in North Carolina: 1) the Brevard Fault Zone in Gorges State Park; and 2) the Upper Chattooga River. We collected three 1L samples from each of 19 streams, but we failed to detect the patch-nosed salamander with any sample. Our results provide additional evidence that this species is likely restricted to the small region from which it is currently known.
