Name: Fallugia paradoxa Grand Canyon Desert Wash Shrubland
Reference: Western Ecology Working Group of...
Description: This Apache plume 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 predominantly occurs in the bottom of drainage channels and desert washes but occasionally occurs on the benches or terraces adjacent to or just above channel bottoms. It occurs from approximately 1100 to 1600 m (3600-5300 feet) elevation, typically in the bottom of flat to low-gradient (1-6°) drainage channels. Soils are fairly well-drained and composed mostly of sand and loam. Bedrock is typically limestone or sandstone. Ground cover is dominated by rocks and gravel. Trees are essentially lacking from this association; however, scattered <i>Pinus edulis, Juniperus osteosperma</i>, and <i>Populus fremontii</i> rarely occur. <i>Fallugia paradoxa</i> dominates this association and is usually found in the short-shrub layer. A wide variety of other short shrubs are typically seen as well. <i>Rhus trilobata</i> is common, while <i>Ephedra viridis, Atriplex canescens, Ericameria nauseosa, Brickellia longifolia</i>, and <i>Encelia resinifera</i> are occasionally present. A sparse dwarf-shrub layer dominated by <i>Gutierrezia sarothrae</i> is typical. <i>Opuntia polyacantha</i> and <i>Agave utahensis</i> also occur sporadically in this layer. The graminoid component frequently includes <i>Bromus rubens</i> and occasionally includes <i>Muhlenbergia porteri, Bromus tectorum, Achnatherum speciosum, Aristida purpurea</i>, and <i>Bouteloua curtipendula</i>. A large variety of different forb species are associated with this community type but cover is low. <i>Artemisia ludoviciana</i> is the most commonly found forb, while <i>Penstemon palmeri, Sphaeralcea ambigua</i>, and <i>Datura wrightii</i> may also be present.
