Name: Atriplex canescens - Ephedra viridis Talus Shrubland
Reference: NatureServe Biotics 2019
Description: This shrubland has a somewhat sparse shrub canopy with cover ranging between 3 and 30%. The shrub layer is codominated by <i>Atriplex canescens</i> and <i>Ephedra viridis</i>, and often has several other shrubs present such as <i>Artemisia bigelovii, Ephedra torreyana, Chrysothamnus viscidiflorus</i>, and <i>Gutierrezia sarothrae</i>. Total vegetative cover ranges from 8 to 35%. The herbaceous layer is diverse but cover rarely exceeds 5%. The most consistent species are the native grasses <i>Achnatherum hymenoides, Aristida purpurea</i>, and <i>Hesperostipa comata</i>. Forbs are rare. Scattered <i>Juniperus osteosperma</i> trees may occur but with cover not exceeding 5%. This association is known from the Colorado Plateau, and occurs on talus slopes. Sites are on moderately steep to steep talus slopes (21-86%), occur between 1217 and 1865 m (4000-6140 feet) elevation, and tend to occur on southeast aspects. The underlying substrate is usually shale, covered by a layer of sandstone talus.
