Black rats are an introduced species in Arkansas, historically spread along river and rail corridors, and NatureServe’s SNA rank, not applicable, reflects that introduced species don’t receive a state conservation status. The record leans toward iNaturalist (11 of 13 records), suggesting casual sightings, not trapping data, document most of what’s known about this rat in the state.
January and May are tied for the year’s peak, 3 sightings each, with February and April showing zero records, too thin a pattern in a 13-record dataset to describe any real seasonal trend beyond occasional detection near White River, Big Lake, and Wapanocca national wildlife refuges.
