Nevada records for the black rat 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 strongest reporting falls in Nevada’s cooler months, when desert travel is easier. That’s a record pattern, not proof that the animal is more numerous then.
The file combines 25 research-grade iNaturalist records and 28 GBIF records. Those 53 records measure documented encounters, not Nevada’s population size. It’s listed as introduced in Nevada. Nevada doesn’t specifically list it under the state’s conservation framework, and the IUCN lists it as Least Concern.
