Sitting at the boundaries and meeting points of the Colorado Plateau, Great Basin, Basin and Range and Mojave Desert physio-geographic zones, animal life in Zion National Park is vast and varied. With elevations ranging from roughly 3800 feet to 8800 feet, the Park encompasses 5000 feet of elevation change in 148,000 acres. With so many varying heights and resultant microclimates and habitats, it is no surprise that Zion is home to over 78 species of mammals, 291 species of birds, 44 species of reptiles and amphibians, and 8 species of fish. Masters in the art of desert heat evasion, many animals take to burrows or dens in the heat of the day, or choose to be nocturnal and use our hours of slumber to live upon the landscape in cooler temperatures.
Though all the animals in Zion are protected by its National Park designation, some animals are of special note. Zion is critical habitat for the Mexican spotted owl, a species classified as threatened on the federal level. A small population of Mojave Desert tortoises is being monitored, along with the endangered Southwestern willow flycatcher.
