Indiana is the southeastern edge of Franklin’s ground squirrel country, and the state’s 14 records map that edge with precision. Nearly all of them come from the northwest corner, Newton, Lake, and Porter counties, the sandy prairie-and-wetland mosaic around Kankakee Sands and the Indiana Dunes. Records from Boone and Tippecanoe counties mark the thin inland fringe.
NatureServe ranks the species Critically Imperiled (S1) in Indiana, its most precarious grade, and the record shows why. This squirrel needs tall grass and undisturbed soil, and Indiana’s version of that habitat now exists mostly in restored parcels. Kankakee Sands, where prairie restoration has brought back exactly the cover it uses, is the kind of place keeping the species on the state’s map at all.
Reports peak from July through September, late in the active season, when young squirrels disperse and adults feed hard ahead of a hibernation that will take them underground for most of the year. With so few records, each verified sighting in the northwestern counties matters, and any record east of that core would genuinely rewrite what’s known about the squirrel’s Indiana range.
