The complete county distribution, spread across 1 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 western yellow bat are anchored by Humboldt-Toiyabe National Forest and Great Basin National Park. 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 monthly pattern is fairly spread out rather than confined to one Nevada season. It tracks observer records and shouldn’t be read as a population count.

The file combines 5 research-grade iNaturalist records and 5 GBIF records. Those 10 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.
