Townsend’s big-eared bat records in Utah center on Snow Canyon State Park, with additional reports from Uinta-Wasatch-Cache National Forest and Fish Springs National Wildlife Refuge, a spread from desert lava-tube country to high forest that matches a bat that roosts in caves, mines, and lava tubes across a wide elevation range.
Utah’s 238 records peak sharply in August, with 67 logged that month, well above the smaller spring bumps in April and May, likely tracking when this whisper-quiet hunter is easiest to detect on acoustic surveys rather than any single seasonal behavior.
NatureServe ranks the species S3, Vulnerable, in Utah, a status that lines up with how easily a disturbed roost can empty out and stay empty for years.
