One of the most elusive species in California is the desert bighorn sheep (Ovis canadensis nelsoni) that live in the dry, desert mountains of southeastern California. Desert bighorn are far from fragile – males are about five feet long and can weigh up to 200 pounds, while the females weigh up to about 150. Despite their size, their keen eyesight and the agility to escape predators up steep rocky slopes, they still face many threats, including disease, human development, expansion and – more recently—a changing climate. Water is critical to their survival in this extreme environment.
