Name: Juniperus osteosperma - (Pinus monophylla) / Arctostaphylos pungens 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 occurs at 1800 to 2100 m (5900-6850 feet) elevation and typically on gentle to moderately steep (1-12°), mid and upper sideslopes and plateaus that are often east-facing. It favors moderately- to rapidly-drained silty clay loams, which are derived from basalt and limestone parent materials. This association supports a characteristically dense short-shrub layer beneath an open tree canopy predominantly comprised of <i>Juniperus osteosperma</i> with some scattered <i>Pinus monophylla</i>. Occasionally, <i>Juniperus osteosperma</i> will occur in the tree subcanopy as well. The tall-shrub stratum is typically ill-defined and may include low covers of <i>Purshia stansburiana</i> and <i>Garrya flavescens</i>. The majority of the cover and diversity in this association occurs in the short-shrub layer which is overwhelmingly dominated by <i>Arctostaphylos pungens</i>. Other notable short-shrub species include <i>Quercus turbinella, Ceanothus greggii</i>, Yucca baccata, and <i>Artemisia tridentata ssp. vaseyana</i>. Dominant graminoids in the sparse herbaceous understory include <i>Poa fendleriana</i> and <i>Bromus tectorum</i>. A variety of forb species, such as <i>Arabis</i> sp., <i>Eriogonum umbellatum, Sphaeralcea ambigua, Comandra umbellata, Penstemon linarioides</i>, and <i>Hymenopappus filifolius</i>, may all occur at low individual covers. This vegetation type exists within a larger expanse of continuous <i>Juniperus osteosperma</i> and <i>Pinus monophylla</i> woodland vegetation.
