The complete county distribution, spread across 8 Nebraska counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Plains pocket mice carry no NatureServe state rank in Nebraska, SNR unranked, and the record leans almost entirely on GBIF specimen data, 26 of the state’s 30 records, since this small, sandy-soil specialist is documented almost exclusively through trapping surveys rather than casual sightings.

July alone accounts for 12 of the year’s monthly-tallied records, more than half the total, a sharp spike that lines up with peak summer trapping-survey timing across the Sandhills and Platte River sand country this species favors; the record shows nothing at all from January through April.
