More than 500 species of plants, from four chief plant communities — open oak woodland, mesquite grassland, floodplain, and granite rock community — inhabit the rock. Vernal pools, ecologically threatened depressions of flora and fauna adapted to harsh environments, contain fragile invertebrate fairy shrimp. Other wildlife includes bats, ringtails, squirrels, and fox. A wide variety of lizards including the Texas horned lizard also make the Enchanted Rock area their home.
