Name: Pinus edulis - Juniperus osteosperma / Ephedra viridis Woodland
Reference: Western Ecology Working Group of...
Description: This woodland association occurs on dry middle and upper slopes of ridges and canyons, as well as on colluvial slopes and benches in eastern Utah and northwestern Colorado. Sites are flat to steep (0-32% slope), mostly on south- or west-facing slopes between 1558 and 2204 m elevation. Soils are coarse, rocky and generally are derived from sedimentary rocks. The tree canopy is characterized by the codominance of <i>Juniperus osteosperma</i> and <i>Pinus edulis</i> trees that are 2-5 m tall with up to 40% cover. The shrub layer is generally sparse and is dominated by <i>Ephedra viridis</i>, which contributes approximately 10% cover. Few other shrubs are present, and because of the low diagnostic value of <i>Ephedra viridis</i>, these associated shrubs have very low cover: <i>Amelanchier utahensis, Artemisia tridentata, Cercocarpus intricatus, Glossopetalon spinescens var. meionandrum, Shepherdia rotundifolia, Artemisia bigelovii</i>, and <i>Mahonia fremontii</i> may be present. Associated graminoids provide low cover and include <i>Poa secunda, Bouteloua gracilis, Pleuraphis jamesii, Hesperostipa comata, Achnatherum hymenoides, Pseudoroegneria spicata</i>, and <i>Pleuraphis jamesii</i>. Forbs are diverse but inconsistent among stands and contribute little cover.
