Name: Atriplex obovata Talus Dwarf-shrubland
Reference: Western Ecology Working Group of...
Description: This saltbush dwarf-shrubland association is currently described from Grand Canyon National Park in northern Arizona. More survey and classification work are needed to fully characterize this type. It occurs on talus sideslopes at 975 to 1150 m (3225-3775 feet) elevation, and is typically found on moderate to steep (15-40°), south- or southeast-facing slopes. Soils are rapidly drained silty or sandy loams that usually overlie limestone or sandstone bedrock. Vegetation is characterized by the dominance of <i>Atriplex obovata</i> in the short-shrub stratum. Tall shrubs are absent. <i>Ephedra torreyana</i> also regularly occurs in the short-shrub layer. A fairly sparse dwarf-shrub layer exists, in which <i>Opuntia basilaris, Gutierrezia sarothrae</i>, and <i>Brickellia atractyloides</i> may sporadically occur. <i>Bromus rubens</i> and <i>Muhlenbergia porteri</i> are frequently present in a well-developed graminoid layer that is typically dominated by non-native annuals. <i>Dasyochloa pulchella</i> and <i>Sporobolus</i> sp. also commonly occur. <i>Cryptantha</i> sp., <i>Thymophylla pentachaeta, Machaeranthera pinnatifida, Lepidium</i> sp., and <i>Phacelia crenulata</i> are common components of the forb understory.
