The hispid pocket mouse is a sandy-soil specialist, a coarse-furred little rodent with fur-lined cheek pouches for hauling seeds back to its burrow. In Louisiana it’s at the far southeastern edge of its range, and the record shows it: just 10 reports since 2000, and NatureServe ranks the species imperiled in the state.
Every one of the four parishes with records sits along the state’s western tier: Vernon, Natchitoches, Beauregard, and Sabine. That’s the longleaf pine and sandy upland country bordering Texas, exactly the dry, loose-soil ground this mouse needs. The rest of Louisiana, heavy on clay, swamp, and alluvial bottomland, simply doesn’t suit it, so the western-leaning map may be closer to real distribution than observer luck this time.
Reports bunch up in November and December, which likely reflects when trappers and field crews have worked those uplands rather than any seasonal habit of the mouse itself. With a record this small, each new parish confirmed matters. A handful of well-placed survey nights in the western parishes would say more about this species in Louisiana than anything currently on file.
