The complete county distribution, spread across 3 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 round tailed ground squirrel have a limited set of named hotspots, led by Tule Springs Fossil Beds National Monument. That gap may reflect where people look and report, so it doesn’t prove absence elsewhere.

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 104 research-grade iNaturalist records and 113 GBIF records. Those 217 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.
