Name: Lycium andersonii - Ephedra (torreyana, viridis) 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 at 925 to 1250 m (3075-4125 feet) elevation, but can be found as low as 750 m (2450 feet). It is primarily found on moderately steep gradients (20-32°), but is also occasionally found on gentler slopes (7-16°). It shows some preference for north- and east-facing slopes, but can also occur on west-facing aspects. Soils are rapidly-drained sandy loams, and the underlying geology is typically sandstone or less frequently limestone or shale. Vegetation is characterized by the codominance of the short shrubs <i>Lycium andersonii</i> and <i>Ephedra torreyana</i>. In rare stands in which <i>Ephedra torreyana</i> is not present, <i>Ephedra viridis</i> occurs in its place. Tall shrubs are absent. The short-shrub layer also commonly includes <i>Encelia farinosa</i>; however, at least 20 different short-shrub associates can occur at low individual covers. A sparse dwarf-shrub layer of <i>Gutierrezia</i> spp. and <i>Opuntia polyacantha</i> occasionally occurs. The graminoid understory is well-developed and can be particularly dense in some stands. <i>Pleuraphis jamesii</i>, Bromus rubens (exotic), <i>Muhlenbergia porteri, Dasyochloa pulchella</i>, and <i>Aristida purpurea</i> are the most common. <i>Bouteloua eriopoda</i> does not occur frequently, but can be dominant in some stands. A somewhat sparse forb understory occasionally includes <i>Porophyllum gracile, Erodium cicutarium</i> (exotic), <i>Sphaeralcea grossulariifolia, Eriogonum inflatum</i>, and <i>Cryptantha</i> spp.  Accession Code: VB.CC.31740.CEGL005150 Plot-observations of this Community Concept: 0
