The southern short-tailed shrew is one of the more frequently recorded small mammals in Louisiana’s database, with 382 records logged statewide. That volume still traces where people have set traps and looked closely, not a direct count of how many shrews live in any one place.

A leaf-litter hunter across the state’s hardwood floor

This shrew tunnels through loose, moist soil and leaf litter, hunting insects, earthworms, and snails, and it delivers a mildly toxic bite that helps subdue larger prey. That means it needs consistently damp ground under a hardwood canopy, conditions found in the hardwood-lined drainages that cut through Kisatchie National Forest’s piney hills, in the live oak and hackberry forest at Fontainebleau State Park on Lake Pontchartrain’s north shore, and on the slightly higher, drier hardwood ridges bordering the Atchafalaya Basin’s wetter backswamp.

Records build through fall

Reports climb steadily from summer into a clear peak in November and December. Cooler, wetter ground in late fall likely brings the shrew closer to the surface litter layer where people and traps are more likely to encounter it, rather than signaling any change in how many shrews are out there.

Status in Louisiana

The southern short-tailed shrew is native to Louisiana and carries a NatureServe rank of S4, apparently secure, in the state.
