Pinyon mice in Texas are restricted to pinyon-juniper woodland on the state’s highest, rockiest ground, the Guadalupe and Davis mountain “sky islands” of the Trans-Pecos, where cliffs and boulder fields set the habitat apart from the desert basins below. NatureServe ranks the species S2, Imperiled, in Texas, a real state-level conservation concern even though the pinyon mouse is Least Concern across its full range; Texas sits at the eastern edge of where this mouse lives at all.
All 80 Texas records come through GBIF with no iNaturalist observations, so specimen surveys account for the entire dataset rather than casual sightings of this small nocturnal rodent. March holds a sharp spike in the record count, but on a sample this size that reads as a single well-timed survey more than a dependable season to look for the species.
