Wisconsin’s Least Chipmunk record is based entirely on 57 GBIF entries, with most dated to July–August. Because Wisconsin lies at the edge of the species’ regional story and the suggested sites span very different landscapes, from Horicon marsh country to Necedah sand country and Mississippi floodplain. Specimen identity and locality deserve more weight than a generic habitat inference.

The records confirm what collections or contributing datasets have reported, not Least Chipmunk abundance. Collection history, possible identification confusion with Eastern Chipmunks, and uneven survey effort can create both clusters and gaps, so the map is not a population estimate.
