The complete county distribution, spread across 10 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 silver haired bat are anchored by Great Basin National Park and Desert National Wildlife Refuge. They show where people have reported it, not how many animals live there.

The Nevada records bridge the state’s southern desert country and its higher central or northern ranges. That broad spread matters more than any single hotspot. 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 19 research-grade iNaturalist records and 47 GBIF records. Those 66 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.
