Animals and Plants
Most mammals are nocturnal, due to the extreme heat, but can be frequently seen at dawn and dusk. Mule deer are the most common large mammal. Bighorn sheep are occasionally seen, as are coyotes. Squirrels, rats, jackrabbits, bats, and cottontails are the more common smaller mammals.
Reptiles are the most common form of life in the park other than birds. Lizards found here include the northern whiptail, desert spiny, and western collared lizard. Most snakes are nocturnal and rarely seen. The midget faded rattlesnake is the only venomous snake in the park.
273 species of birds have been seen in the park, including seasonal and permanent residents. Ravens are common throughout the desert. Inyon jays, scrub jays, juniper titmice and black-throated gray warblers are common in the pinyon-juniper "forest". Turkey vultures and white-throated swifts are frequently seen as well.
Vegetation in the desert is sparse. The most common plant life includes pinyon juniper and a number of desert shrubs, such as blackbrush, greasewood, yucca, big and sand sagebrush, and prickly pear cactus.
