The complete county distribution, spread across 3 Nevada counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Nevada has only 10 fringed myotis records from 2000 to 2026. Clark County supplies 8 of them, with one each from Washoe and Nye, and July holds 6, but a set this small can’t establish a hotspot or a reliable season.

The file combines 2 research-grade iNaturalist records and 9 GBIF records; with the overlap between them removed, that’s 10 distinct records, which measure documented encounters, not Nevada’s population size. It’s native to Nevada. Nevada doesn’t specifically list it under the state’s conservation framework, and the IUCN lists it as Least Concern.
