The complete county distribution, spread across 9 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 spotted bat are anchored by Walker River State Recreation Area and Fort Churchill State Historic Park. They show where people have reported it, not how many animals live there.

The named sites give this Nevada record set more than one geographic anchor. That spread is more informative than treating the statewide total as one uniform pattern. 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 15 research-grade iNaturalist records and 22 GBIF records. Those 37 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.
