Name: Atriplex confertifolia - Lycium andersonii Shrubland Reference: Western Ecology Working Group of... Description: This xeromorphic shrubland association has been described locally from areas of rolling 'badlands' terrain in the eastern part of Grand Canyon National Park in northwestern Arizona. Elevation ranges from 950-1460 m. This vegetation is an unusual mixture of Mojavean and Colorado Plateau species, and may be unique to the Grand Canyon. Similar vegetation has also been reported from California and may also occur in southern Nevada. It is not known if this association represents the same vegetation type as the stands reported from California. Sites occur on all aspects and although slopes are moderate to gentle (<40%), the substrates are unstable and prone to surface movement. Substrates are shallow, gravelly, poorly developed soil derived from silt- and mud-stone shale. Stands have an open, short woody canopy (0.5-2 m tall) that is dominated by the facultatively deciduous shrub, Atriplex confertifolia, or codominating with Lycium andersonii. Other common shrubs and dwarf-shrubs may include Ephedra nevadensis, Ephedra torreyana, Acacia greggii, Encelia frutescens, Tiquilia latior, and Gutierrezia sarothrae. Cacti are common and may include Opuntia basilaris, Opuntia erinacea, Echinocereus engelmannii and Echinocactus polycephalus. The sparse herbaceous layer is dominated by the introduced annual Bromus rubens.  Accession Code: VB.CC.27184.ATRIPLEXCONFERT Plot-observations of this Community Concept: 0
