Coypu, also called nutria, are formally listed as invasive in Arkansas, with USGS NAS documenting 99 nonindigenous occurrences and an established population, well beyond the 37 records tracked in this dataset; NatureServe’s SNA rank reflects that introduced species don’t receive a state conservation status. The record leans almost entirely on iNaturalist (36 of 37 records), suggesting casual sightings, not trapping surveys, drive most of what’s logged here.
Records peak in the first third of the year, January through April together account for 21 of the 37 sightings, more than half the total, likely tracking cooler-season visibility along White River and Cache River wetlands before summer vegetation growth makes this large semi-aquatic rodent harder to spot.
