Least chipmunks carry NatureServe’s S1 rank in Nebraska, critically imperiled, despite the species’ secure G5 global rank, a stark state-level status for a chipmunk that’s genuinely marginal here at the southeastern edge of its range. All 10 of the state’s records are iNaturalist observations, mirrored in GBIF, so casual photographs, 8 of them from Sioux County in the far northwest, account for what’s documented about this species in Nebraska.
Records scatter thin across nine months, one or two apiece from March through November, too sparse a dataset to draw any real seasonal conclusion, consistent with a species this critically imperiled turning up only occasionally in the state’s wildlife record.
