Bighorn sheep inhabit alpine meadows, grassy mountain slopes, and foothill country near rugged, rocky cliffs and bluffs. [8] Since bighorn sheep cannot move through deep snow, they prefer drier slopes, where the annual snowfall is less than about 150 cm (60 in) per year. [8] A bighorn's winter range usually has lower elevations than its summer ...
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]
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.

There are only approximately 80,000 North American bighorn sheep on the continent currently — much less than the between 150,000 and 200,000 that existed before the 1800’s.
Bighorn sheep. Bighorn sheep (Ovis canadensis) were once very numerous in western United States and were an important food source for humans. The "Sheep eaters", a band of Shoshone people, lived year-round in Yellowstone until 1880. Their principal food was bighorn sheep and they made their bows from sheep horns. By 1900, during an "epoch of ...
The bighorn sheep (Ovis canadensis) [5] is a species of sheep in North America [6] with large horns. The horns can weigh up to 30 pounds (14 kg), while the sheep themselves weigh up to 300 pounds (140 kg). [7]
The Badlands bighorn (Ovis canadensis auduboni), commonly known as Audubon's bighorn sheep, is an extinct subspecies or population of bighorn sheep of the northern Great Plains in North America. Its existence as a separate subspecies is disputed.
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]
