Name: Larrea tridentata - Ambrosia dumosa - Fouquieria splendens Shrubland
Reference: Western Ecology Working Group of...
Description: This creosotebush shrubland association is currently described from Grand Canyon National Park in Arizona. More survey and classification work are needed to fully characterize this type. It typically occurs on sideslopes, terraces, and plateaus at 500 to 600 m (1650-1950 feet) elevation, but can be found as low as 425 m (1400 feet). It is primarily found on fairly gentle gradients (2-10°), but also occasionally occurs on steeper slopes (20°). Soils are rapidly-drained silty loams that typically lie above limestone bedrock. Vegetation is characterized by the codominance of the tall shrubs <i>Larrea tridentata</i> and <i>Fouquieria splendens</i>, and the dwarf-shrub <i>Ambrosia dumosa</i>. <i>Ephedra fasciculata</i> frequently occurs in a relatively weak short-shrub layer, while <i>Psorothamnus</i> sp., <i>Opuntia acanthocarpa</i>, and <i>Encelia farinosa</i> also occur occasionally. The dwarf-shrub layer invariably includes the cactus <i>Opuntia basilaris</i>. Few graminoids occur, but <i>Dasyochloa pulchella</i> does appear fairly consistently. <i>Cryptantha</i> spp., <i>Dichelostemma capitatum</i>, and <i>Phacelia</i> sp. are the most frequent forbs. <i>Eriogonum inflatum</i> and <i>Gilia</i> sp. also sporadically occur in this layer.
