Name: Cercocarpus montanus Shrub Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Shrublands included in this alliance are found on breaks and foothill, mountain and canyon slopes throughout much of the western U.S. Sites are variable but are generally xeric and rocky with moderate to very steep south-facing slopes. Soils are typically shallow and well-drained with abundant rock outcrops. Soil texture is variable. Vegetation included in this alliance is characterized by a sparse shrub layer 1-2 m tall dominated by Cercocarpus montanus. Occasional trees, such as Juniperus deppeana, Pinus edulis, Quercus gambelii, and Quercus grisea, may be present. Associated shrubs and dwarf-shrubs include Agave parryi, Ageratina herbacea, Dasylirion wheeleri, Ericameria laricifolia, Mimosa aculeaticarpa var. biuncifera, Nolina microcarpa, Robinia neomexicana, Symphoricarpos oreophilus, Yucca baccata, and the shrubby cacti species Opuntia engelmannii and Opuntia imbricata. The herbaceous layer is sparse to moderately dense and usually dominated by perennial grasses such as Muhlenbergia spp., Bothriochloa barbinodis, Bouteloua spp., Schizachyrium cirratum, and Achnatherum lobatum (= Stipa lobata). Forbs may be diverse and include Artemisia spp., Eriogonum spp., Hedeoma plicata, Heliomeris spp., Mirabilis spp., and Viguiera dentata. Diagnostic of this alliance is a relatively sparse shrub canopy (10-25% cover) dominated by Cercocarpus montanus and an abundant herbaceous layer dominated by perennial graminoids.  Accession Code: VB.CC.24881.CERCOCARPUSMONT Plot-observations of this Community Concept: 0
