Name: Ephedra fasciculata / Mixed Semi-Desert Grasses Shrubland
Reference: Western Ecology Working Group of...
Description: This 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 or rarely in drainages and valley bottoms at 675 to 950 m (2250-3075 feet) elevation, but can be found as high as 1350 m (5500 feet). It is primarily found on moderate gradients (15-25°), but is occasionally found on steeper slopes (25-35 degrees). Soils are rapidly-drained sandy loams that typically obscure various underlying bedrock types. Vegetation is characterized by the dominance of <i>Ephedra fasciculata</i> in the short-shrub stratum, together with a strong mixed-species graminoid understory. Tall shrubs are rare and sparse. The short-shrub layer also includes <i>Encelia farinosa</i> and sometimes <i>Ferocactus cylindraceus</i>. <i>Gutierrezia sarothrae</i> is the most common component of a relatively sparse dwarf-shrub layer. <i>Muhlenbergia porteri</i> and <i>Pleuraphis jamesii</i> dominate the well-developed graminoid understory. Other common graminoids include <i>Achnatherum speciosum, Dasyochloa pulchella, Aristida purpurea</i>, and <i>Vulpia octoflora</i>. The non-native <i>Bromus rubens</i> occurs in almost all stands. <i>Artemisia ludoviciana, Machaeranthera pinnatifida</i>, and <i>Erodium cicutarium</i> are the most common forbs. A relatively high cover of moss occurs in some stands.
