Nevada records for the white tailed antelope squirrel are anchored by Valley of Fire State Park and Red Rock Canyon National Conservation Area. They show where people have reported it, not how many animals live there.

These sites place the Nevada record pattern firmly in the state’s southern desert country. The protected lands also span springs, canyons, and open basin terrain. 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 1,383 research-grade iNaturalist records and 1,827 GBIF records. Those 3,210 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.
