Name: Pinus monophylla - Juniperus osteosperma / Purshia stansburiana Woodland Reference: NatureServe Biotics 2019 Description: This pinyon-juniper woodland association is currently described from Canyon-Parashant National Monument in Arizona. It also occurs in Mojave National Preserve in California. More survey and classification work are needed to fully characterize this type. It typically occurs at 1775 to 1850 m (5860-6050 feet) elevation on gently to moderately sloping (1-14°) high-level plateaus, low-level valley bottoms, and mid to upper sideslopes. It often favors south-facing aspects. Soils tend to be well- or rapidly-drained silty clay loams derived from limestone parent materials. This woodland association supports sparse to dense tree canopy of <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i>. <i>Purshia stansburiana</i> dominates and characterizes the shrub strata. Various short shrubs such as <i>Gutierrezia sarothrae, Ephedra viridis, Artemisia tridentata</i>, and <i>Yucca baccata</i> occur occasionally at relatively low individual covers. <i>Cylindropuntia whipplei</i> and <i>Opuntia</i> sp. are frequent components of the very sparse dwarf-shrub stratum. The herbaceous understory is poorly developed; frequent graminoids include <i>Bromus tectorum, Bouteloua gracilis, Poa fendleriana</i>, and <i>Elymus elymoides</i>, while notable forbs include <i>Eriogonum umbellatum, Cordylanthus parviflorus, Frasera albomarginata</i>, and <i>Comandra umbellata</i>. This vegetation type occurs within a large matrix of pinyon-juniper vegetation types.  Accession Code: urn:lsid:vegbank.org:commConcept:34157-{BCF2A688-0BF2-48AB-9FC1-E9255242B744} Plot-observations of this Community Concept: 0
