Name: Larrea tridentata - Encelia farinosa - 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 primarily occurs on xeric desert sideslopes at 475 to 575 m (1550-1900 feet) elevation, but can be found as high as 645 m (2100 feet). It is typically found on low gradients (2-10°) and on south- or east-facing aspects, but is also common on steeper slopes (20-28°). Soils are well- to rapidly-drained sandy loams or clays, and the bedrock is typically limestone. Vegetation is characterized by the codominance of three shrub species: the tall shrubs <i>Larrea tridentata</i> (3-5%) and <i>Fouquieria splendens</i> (3-5%), and the short shrub <i>Encelia farinosa</i> (5-10%). In the short-shrub layer, <i>Encelia farinosa</i> is invariably accompanied by <i>Ephedra fasciculata</i>. <i>Krameria erecta, Ferocactus cylindraceus</i>, and <i>Opuntia acanthocarpa</i> also occur fairly frequently. A very weak dwarf-shrub layer exists in which <i>Opuntia basilaris</i> occurs occasionally. <i>Vulpia octoflora</i> and <i>Dasyochloa pulchella</i> are occasionally present in a meager graminoid layer. <i>Plantago ovata, Phacelia</i> sp., and <i>Allionia incarnata</i> sporadically occur in the fairly sparse forb layer.
