Climate Change and National Parks: A Survival Guide for a Warming World -- Bighorn Sheep in the Southwest
Canyonlands National Park is one of the most rugged national parks, with a harsh summer sun that bakes the dry, canyon-riddled landscape. But those deep canyons’ steep rocky slopes, which offer ample grasses and shrubs, and an openness that puts predators at a disadvantage, are an optimal environment for bighorn sheep. In fact, Canyonlands’ bighorn population has been so stable that Utah’s wildlife biologists long relied on it for stock to re-establish herds elsewhere in the state.
