Nevada records for the muskrat are anchored by Stillwater National Wildlife Refuge and Washoe Lake State Park. They show where people have reported it, not how many animals live there.
These sites put the Nevada record pattern in the state’s northern basins and wetland country. That setting is distinct from the heavily visited parks around Las Vegas. 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 171 research-grade iNaturalist records and 607 GBIF records. Those 778 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.
