Name: Juniperus osteosperma - (Pinus monophylla) / Ceanothus greggii Woodland Reference: NatureServe Biotics 2019 Description: This pinyon-juniper woodland association is currently described from Grand Canyon-Parashant National Monument Arizona. More survey and classification work are needed to fully characterize this type. It occurs at 1800 to 2050 m (5890-6700 feet) elevation on gently sloping (1-9°) sideslopes and high-level plateaus. It seems to often favor north-facing aspects, but can also occur on east- and south-facing slopes as well. Soils tend to be moderately to well-drained clay silt loams that are typically derived from basalt or limestone parent materials. The tree canopy is comprised primarily of <i>Juniperus osteosperma</i> with some occasional <i>Pinus monophylla</i>. Many stands support a sparse subcanopy consisting mostly of <i>Juniperus osteosperma</i>. <i>Ceanothus greggii</i> is the characteristic shrub species in this association, and <i>Artemisia tridentata</i> also occurs in most stands at low cover. Various other shrub species, such as <i>Cylindropuntia whipplei, Quercus gambelii, Purshia stansburiana</i>, and <i>Gutierrezia sarothrae</i>, frequently occur. <i>Bouteloua gracilis, Poa fendleriana, Elymus elymoides</i>, and <i>Bouteloua curtipendula</i> are the dominant grasses in a sparse herbaceous understory. <i>Penstemon linarioides, Camissonia</i> sp., <i>Eriogonum umbellatum</i>, and <i>Hymenoxys richardsonii</i> are common forb species. This association can occur over large areas, often as part of an extensive network of various <i>Juniperus osteosperma - Pinus monophylla</i> vegetation types.  Accession Code: urn:lsid:vegbank.org:commConcept:34063-{E3279768-447C-4CC2-B524-6D119E574246} Plot-observations of this Community Concept: 0
