The Sierra Nevada bighorn sheep (Ovis canadensis sierrae) is subspecies of bighorn sheep unique to the Sierra Nevada mountains of California. [3] A 2016 genetics study confirmed significant divergence between the three subspecies of North America's bighorn sheep: Sierra Nevada bighorn sheep, Rocky Mountain bighorn sheep and desert bighorn sheep.

Only 39% of the 115 bighorn sheep translocations are persisting in 6 Rocky Mountain states. Populations of 100 or more sheep now occur in 10 national park units, populations of 100-200 sheep in 5 units, and populations of more than 500 sheep in 5 units. Populations of fewer than 100 animals exist in 5 other park units. [1]
The National Bighorn Sheep Center (formerly known as the National Bighorn Sheep Interpretative Center) is a 2,775-square-foot (257.8 m 2) Interpretive Center [1] dedicated to public education about the biology and habitat of the Rocky Mountain Bighorn Sheep with specific focus on the currently largest herd of Rocky Mountain Bighorn sheep in the coterminous United States that winter in the ...
Desert bighorn sheep populations have trended upward since the 1960s. The upward trend was caused by conservation measures, including habitat preservation. In 1978, desert bighorn sheep populations were estimated at 8,415-9,040. [15] A state-by-state survey published in 1985 estimated the overall US desert bighorn sheep population at 15,980. [16]

For example, in bighorn sheep, when two males meet each other, each tilts its head towards each other to give a good view of the horns. If the horns are approximately the same size, the sheep may fight to establish dominance. However, if the horn of one sheep is larger than the other, the sheep with the smaller horns will generally back off.
