Nebraska is near the heart of the hispid pocket mouse’s range, and the state’s record set shows what a well-suited landscape looks like: 104 reports across 27 counties since 2000, from the Sandhills to the southern border counties. NatureServe ranks the species secure in the state, a stark contrast with its imperiled standing at the range edges farther south and east.
Cherry County leads the tally, which makes sense on two levels. It holds a big share of the Sandhills, a sea of grass-stabilized dunes with the loose, sandy soil this mouse digs into, and it’s home to Valentine National Wildlife Refuge and some of the most surveyed grassland in the state. Hooker County, also deep in the Sandhills, follows the same pattern. Records from Richardson, Cass, and Gage counties show the mouse reaching the state’s eastern farmland edge too.
Nearly every report lands between June and September, with July the heaviest month. Pocket mice don’t hibernate outright, but they go torpid and stay underground through cold snaps, so the summer bulge mixes real above-ground activity with the simple fact that small-mammal trapping is warm-weather work. One caution for the recent picture: the newest record in this set dates to 2018, so the current decade is largely unwritten.
