the great basin, mojave desert, and colorado plateau converge at zion and the kolob canyons. this, along with the varied topography of canyon–mesa country, differing soil types, and uneven water availability, provides diverse habitat for the equally diverse mix of plants and animals that live in the area. the park is home to 289 bird, 79 mammals, 28 reptiles, 7 fish, and 6 amphibian species. these organisms make their homes in one or more of four life zones found in the park: desert, riparian, woodland, and coniferous forest.
