The complete county distribution, spread across 14 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 little pocket mouse are anchored by Desert National Wildlife Refuge 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 8 research-grade iNaturalist records and 1,916 GBIF records. Those 1,924 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.
