Some of the native grasses found in Grand Canyon National Park include Indian ricegrass, blue and black gramma, big galleta, and side oats gramma. Cheatgrass, smooth brome, red brome and Kentucky bluegrass are non-native, introduced species that often invade disturbed sites and compete with grasses indigenous to the park. For a complete list of plant species in Grand Canyon National Park, see the Grand Canyon Plant List.
