Nevada records for the north american porcupine have a limited set of named hotspots, led by Humboldt-Toiyabe National Forest. That gap may reflect where people look and report, so it doesn’t prove absence elsewhere.

These sites tie the Nevada record pattern to the state’s long mountain spine. Records from separate ranges matter because Nevada’s high country is broken into isolated peaks. The strongest reporting falls in summer, when Nevada’s high country is easiest to reach but low deserts are hottest. That may shape where observers submit records.

The file combines 26 research-grade iNaturalist records and 86 GBIF records. Those 112 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.
