Bighorn sheep carry a NatureServe S2 imperiled rank in Nebraska despite ranking “common” in this occurrence-based bucket, a reminder that a healthy record count doesn’t equal a secure population. The state’s herds are small, reintroduced bands confined to rugged Pine Ridge and badlands terrain in the northwest, far from the species’ historic range across the plains. Nearly all of the 128 records, 127 of them, come from iNaturalist, suggesting most documentation traces to hikers and photographers rather than agency survey work.
Records show three separate peaks, May, August, and November (14-16 sightings each), rather than one dominant season, a pattern that likely tracks both lambing-season visibility in spring and the fall rut when rams become more active and conspicuous.
