Name: Pinus edulis - (Juniperus monosperma, Juniperus osteosperma) / Hesperostipa comata Woodland Reference: Western Ecology Working Group of... Description: This woodland association is known from western and south-central Colorado and eastern Utah. Stands occur on a variety of sites from flat or gentle lower slopes, benches, wash terraces, mesatops to steep colluvial slopes to montane alluvial fans. Parent materials are frequently sandstone or shale. This woodland is characterized by the dominance or codominance of <i>Pinus edulis</i> in an open evergreen tree canopy. <i>Juniperus osteosperma</i> or <i>Juniperus monosperma</i> may codominate some stands, and <i>Juniperus scopulorum</i> may also be present. The sparse to moderately dense herbaceous layer is dominated by the perennial bunchgrass <i>Hesperostipa comata (= Stipa comata)</i>, with <i>Achnatherum hymenoides (= Oryzopsis hymenoides), Koeleria macrantha, Bouteloua gracilis, Pleuraphis jamesii (= Hilaria jamesii)</i>, and <i>Pascopyrum smithii</i> often present to common. Forb cover is generally sparse but may include <i>Heterotheca villosa, Hymenoxys</i> spp., <i>Artemisia dracunculus (= Artemisia dracunculoides), Oxytropis lambertii, Castilleja</i> sp., <i>Eriogonum jamesii</i>, and <i>Sphaeralcea coccinea</i>. Scattered shrubs and dwarf-shrubs may also be present, such as <i>Cercocarpus montanus, Quercus gambelii, Atriplex canescens, Artemisia frigida, Ephedra viridis</i>, or <i>Gutierrezia sarothrae</i>. <i>Opuntia polyacantha</i> and <i>Yucca glauca</i> are often present. Diagnostic of this woodland association is the dominance or codominance of <i>Pinus edulis</i> in the tree canopy and a <i>Hesperostipa comata</i>-dominated herbaceous layer.  Accession Code: VB.CC.32968.CEGL000797 Plot-observations of this Community Concept: 0
