Nevada records for the house mouse are anchored by Stillwater National Wildlife Refuge and Ruby Lake National Wildlife Refuge. They show where people have reported it, not how many animals live there.
The Nevada records stretch from southern desert country toward the state’s northern basins. They show a wider in-state footprint than the best-known southern sites alone. 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 13 research-grade iNaturalist records and 109 GBIF records. Those 122 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.
