The complete county distribution, spread across 7 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 california ground squirrel are anchored by Washoe Lake State Park and Humboldt-Toiyabe National Forest. They show where people have reported it, not how many animals live there.

The Nevada records connect mountain country with northern basins and wetlands. That contrast gives a fuller picture than one well-visited range would. 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 619 research-grade iNaturalist records and 680 GBIF records. Those 1,299 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.
