Subspecies in Nevada

Nevada has desert bighorn sheep (Ovis canadensis nelsoni) in its southern desert ranges; the desert bighorn is Nevada’s state animal.

Nevada records for the bighorn sheep are anchored by Lake Mead National Recreation Area and Humboldt-Toiyabe National Forest. They show where people have reported it, not how many animals live there.

The Nevada records bridge the state’s southern desert country and its higher central or northern ranges. That broad spread matters more than any single hotspot. 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 2,513 research-grade iNaturalist records and 2,134 GBIF records. Those 4,647 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.
