Hierarchy Level: Association
Type Concept: This Apache plume shrubland association occurs in northern Arizona and southeastern California. It 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 Pinus edulis, Juniperus osteosperma, and Populus fremontii rarely occur. Fallugia paradoxa dominates this association and is usually found in the short-shrub layer. A wide variety of other short shrubs are typically seen as well. Rhus trilobata is common, while Ephedra viridis, Atriplex canescens, Ericameria nauseosa, Brickellia longifolia, and Encelia resinifera are occasionally present. A sparse dwarf-shrub layer dominated by Gutierrezia sarothrae is typical. Opuntia polyacantha and Agave utahensis also occur sporadically in this layer. The graminoid component frequently includes Bromus rubens and occasionally includes Muhlenbergia porteri, Bromus tectorum, Achnatherum speciosum, Aristida purpurea, and Bouteloua curtipendula. A large variety of different forb species are associated with this community type but cover is low. Artemisia ludoviciana is the most commonly found forb, while Penstemon palmeri, Sphaeralcea ambigua, and Datura wrightii may also be present.
