Name: Pinus monophylla - Juniperus osteosperma / Bouteloua gracilis Woodland
Reference: Western Ecology Working Group of...
Description: This pinyon-juniper woodland association is currently described from Grand Canyon-Parashant National Monument in Arizona. More survey and classification work are needed to fully characterize this type. It typically occurs at 1875 to 1925 m (6150-6300 feet) elevation on gently sloping (1-7°) high-level plateaus and sideslopes, and occurs across all aspects. Soils are moderately- to well-drained silty clays derived from basalt parent material. This association typically supports an open tree canopy consisting of <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i>. In half of the stands, there is a notable subcanopy comprised also of <i>Pinus monophylla</i> and <i>Juniperus osteosperma</i>. Beneath the tree canopy is an extremely sparse short-shrub layer of <i>Ceanothus greggii</i> and <i>Artemisia tridentata</i>. Dwarf-shrubs such as <i>Gutierrezia sarothrae</i> and <i>Opuntia</i> sp. often occur at trace covers. <i>Bouteloua gracilis</i> dominates a well-developed graminoid component, while <i>Poa fendleriana, Elymus elymoides</i>, and <i>Aristida purpurea</i> are frequent at lower covers. Common forbs include <i>Penstemon linarioides, Eriogonum umbellatum</i>, and <i>Hymenoxys richardsonii</i>.
