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.[4] Sierra Nevada bighorn sheep were listed as a federally endangered subspecies in 2000.[5] In 2016, over 600 Sierra bighorn remained in the wild.[6] However, in 2023, more recent studies indicate that the population has dropped to approximately half, or 300. This is due to high levels of mountain lion predation combined with heavy snowfall, threatening the species even further. [7]
