Name: Pinus edulis - (Juniperus monosperma, Juniperus osteosperma) / Hesperostipa comata Woodland Reference: Western Ecology Working Group of... Description: This woodland association is known from southwestern Colorado and likely occurs into eastern Utah. Stands occur on a variety of sites from flat or gentle lower slopes, benches, mesa tops to moderately steep slopes on montane alluvial fans. Parent materials are frequently sandstone and shale. Aspects are often western or southern, but have been reported from the east-facing slopes. This woodland is characterized by the dominance or codominance of Pinus edulis in an open evergreen tree canopy. Juniperus osteosperma or Juniperus monosperma may codominate some stands, and Juniperus scopulorum may also be present. The sparse to moderately dense herbaceous layer is dominated by the perennial bunchgrass Hesperostipa comata (= Stipa comata) with Achnatherum hymenoides (= Oryzopsis hymenoides), Koeleria macrantha, Bouteloua gracilis, Pleuraphis jamesii (= Hilaria jamesii), and Pascopyrum smithii often present to common. Forb cover is generally sparse, but may include Heterotheca villosa, Hymenoxys spp., Artemisia dracunculus (= Artemisia dracunculoides), Oxytropis lambertii, Castilleja sp., Eriogonum jamesii, and Sphaeralcea coccinea. Scattered shrubs and dwarf-shrubs may also be present, such as Cercocarpus montanus, Quercus gambelii, Atriplex canescens, Artemisia frigida, or Gutierrezia sarothrae. Opuntia polyacantha and Yucca glauca are often present. Diagnostic of this woodland association is the dominance or codominance of Pinus edulis in the tree canopy and a Hesperostipa comata-dominated herbaceous layer.  Accession Code: VB.CC.24454.PINUSEDULISJUNI Plot-observations of this Community Concept: 0
