The complete county distribution, spread across 4 Nevada counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Nevada records for the fringed myotis are anchored by Sheldon National Wildlife Refuge and Black Rock Desert. They show where people have reported it, not how many animals live there.

The Nevada records stretch from southern desert country toward the state’s northern basins. They show a wider in-state footprint than the best-known southern sites alone. The strongest reporting falls in summer, when Nevada’s high country is easiest to reach but low deserts are hottest. That may shape where observers submit records.

The file combines 2 research-grade iNaturalist records and 29 GBIF records. Those 31 records 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.
