Norway rats are an introduced commensal species in South Carolina, and NatureServe’s SNA rank, not applicable, reflects that introduced species don’t receive a state conservation status. With only 13 records total, split fairly evenly between iNaturalist (9) and GBIF (8), this is a thinly documented species here, likely because South Carolina’s rural refuge landscape offers fewer opportunities for people to encounter this rat than dense urban settings would.
Records scatter across eight months with a modest September peak (3 sightings) and complete silence from June through August, too sparse a pattern to describe a confident seasonal trend, though a species that breeds year-round makes any true seasonality unlikely to begin with.
