Hierarchy Level:  Association

Type Concept: 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 composed of Juniperus osteosperma with some scattered Pinus monophylla. Occasionally, Juniperus osteosperma will occur in the tree subcanopy as well. The tall-shrub stratum is typically ill-defined and may include low covers of Purshia stansburiana and Garrya flavescens. The majority of the cover and diversity in this association occurs in the short-shrub layer which is overwhelmingly dominated by Arctostaphylos pungens. Other notable short-shrub species include Quercus turbinella, Ceanothus greggii, Yucca baccata, and Artemisia tridentata ssp. vaseyana. Dominant graminoids in the sparse herbaceous understory include Poa fendleriana and Bromus tectorum. A variety of forb species, such as Arabis sp., Eriogonum umbellatum, Sphaeralcea ambigua, Comandra umbellata, Penstemon linarioides, and Hymenopappus filifolius, may all occur at low individual covers. This vegetation type exists within a larger expanse of continuous Juniperus osteosperma and Pinus monophylla woodland vegetation.
