The southern meadow jumping mouse needs wet ground more than open grass. It forages along stream edges and marshy sedge that stay damp through summer, then packs on fat for a hibernation that can run seven months or more. In the Kansas Flint Hills, that likely means the creek bottoms and spring-fed draws of Geary and Riley counties, not the dry upland bluestem itself.
Records cluster tightly between May and September, when the mouse is active and feeding, with August the highest month at 16 sightings and June close behind at 12. Outside that window there’s nothing, consistent with a species that disappears underground for most of the year rather than one that’s simply hard to find in winter.
The most recent confirmed record on file dates to 2016, a decade old now, which says as much about how rarely anyone surveys these wet-meadow pockets as it does about whether the mouse is still there.
