Indiana’s least shrew record is thin, just 23 entries, and every one of them comes from the northern third of the state. That pattern fits a species built for the grasslands of the South and southern Plains, reaching only the northern edge of its range here.
A prairie restoration doing exactly what it’s meant to
Least shrews need dense, low grass cover to run their narrow surface runways, and Kankakee Sands, one of the Midwest’s largest tallgrass prairie and savanna restorations, sits in the historic Grand Kankakee Marsh country of Indiana’s northwest corner. A shrew record there is a small sign that the restored grassland is doing its job, rebuilding the thick, matted cover this species needs to move around hidden from predators.
A social shrew at the cool edge of its comfort zone
Unlike most shrews, which fight off their own kind, least shrews often nest and huddle in groups, a habit that likely helps them survive cold snaps that push closer to their tolerance limit this far north than they would in Texas or Florida. Indiana’s other two locations, Indiana Dunes National Park and Pokagon State Park, both offer the same kind of dense grass and wetland-edge cover in the Lakes and Moraines country, well north of where this species usually turns up.
Status in Indiana
NatureServe ranks the North American least shrew S4, apparently secure, and native to Indiana. Its foothold here depends on holding onto grassy, low-cover habitat at the edge of a range centered hundreds of miles to the south, which makes places like Kankakee Sands more important to its Indiana presence than the species’ broad Least Concern status might suggest.
