The complete county distribution, spread across 12 Utah counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Utah has only a handful of confirmed hoary bat records, about 70 in total, and most come from a scatter of forests and refuges rather than any single hotspot: Uinta-Wasatch-Cache National Forest, Manti-La Sal National Forest, Fish Springs National Wildlife Refuge, and Glen Canyon National Recreation Area each contribute just one or two. That spread fits a solitary, tree-roosting bat that spends nights foraging over open country and days hidden in foliage, easy to miss even where it’s present.

Records rise through spring and peak in May, before dropping off by midsummer, a pattern more likely to reflect when acoustic surveys and mist-netting happen than when the bats are most active. NatureServe rates the species only apparently secure as a breeder in Utah, but ranks it G3, uncommon, across its whole range, so Utah’s few records carry more weight than the small count suggests.
