Bighorn sheep in Sequoia National Park are a remarkable species, inhabiting rugged terrain from 4,790 to 14,100 feet elevation. These majestic creatures prefer open, rocky areas with sparse vegetation, allowing them to spot predators easily. Conservation efforts have helped increase their population from a mere 100 in 1995 to over 500 today, spread across 11 herds. Sequoia National Park provides crucial habitats like Big Arroyo and Laurel Creek, offering summer forage and protection from disease transmission risks associated with domestic sheep.
