The complete county distribution, spread across 2 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 fox squirrel are anchored by Ruby Mountains and Ruby Lake National Wildlife Refuge. They show where people have reported it, not how many animals live there.

These sites tie the Nevada record pattern to the state’s long mountain spine. Records from separate ranges matter because Nevada’s high country is broken into isolated peaks. 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 56 research-grade iNaturalist records and 31 GBIF records. Those 87 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.
