Long-tailed vole in Arizona is confined to high, moist mountain meadows in ranges like the White Mountains and the Kaibab Plateau, well above the desert floor most visitors associate with the state. Its mid-tier record reflects a real population concentrated in a small slice of Arizona’s highest country.
September alone accounts for 77 of the year’s sightings, by far the sharpest spike in this dataset, almost certainly a single concentrated trapping survey rather than a true one-month population boom; the near-blank record for the rest of the year says more about when surveys ran than about the vole disappearing.
