Nevada records for the california myotis are anchored by Stillwater National Wildlife Refuge and Ruby Lake National Wildlife Refuge. 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 monthly record pattern has both winter and summer strength. In Nevada, that split can reflect access to low desert sites and high mountain sites at different times.

The file combines 2 research-grade iNaturalist records and 69 GBIF records. Those 71 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.
