Missouri’s Franklin’s ground squirrel records pile into the state’s northwest corner. Nodaway County alone holds 10 of 23, and with Atchison and Holt counties it forms a tight cluster along the Missouri River floodplain and loess hills. The rest of the state contributes only scattered singles. Missouri marks the southeastern edge of the species’ range, and the map reads exactly like a range edge: a solid core in one corner, then a fade.
The calendar leans late. Reports peak in September and October, when squirrels are feeding urgently ahead of hibernation and young animals are wandering onto new ground. It’s a short window of visibility for an animal that spends most of the year in its burrow and rarely strays from dense grass when it’s out.
NatureServe ranks the species Imperiled (S2) in Missouri. That grade, the range-edge geography, and the squirrel’s need for untilled tallgrass all point the same direction: the northwestern counties are the stronghold, and their remnant prairies and grassy rights-of-way carry outsized importance. A new verified record anywhere south or east of that corner would be real news for the species in the state.
