Desert Grassland

Desert grassland is equivalent to Brown's semidesert grassland. It is a perennial "grass-scrub dominated landscape," which occurs below the Mogollon Rim between 1000-2000 meters elevation. The most common grass species include Hilaria mutica, Bouteloua eriopoda, Bouteloua curtipendula, Aristida spp., Dasyochloa pulchella. Shrubs and cacti are common in over-grazed areas and may become the dominant species. The most common shrubs are Prosopis glandulosa, Mimosa aculeaticarpa, Larrea tridentata, and Ziziphus obtusifolia.
