Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Two-needle Pinyon - Utah Juniper / James'' Galleta Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland association is documented from the Colorado Plateau in western Colorado and Utah. The vegetation is characterized by an open canopy of Pinus edulis and Juniperus osteosperma trees with between 5 and 15% cover and an understory dominated by Pleuraphis jamesii with up to 10% cover. Shrubs do not form a layer (<5% total cover), but scattered individuals of several species may be present. It occurs on ridges, hills, canyon sides and mesatops on gentle to steep slopes (4-23°) on warm aspects, and lies between 1411 and 2020 m (4630-6625 feet) in elevation. Soils are rapidly drained loamy sands.

Floristics: The vegetation is characterized by an open canopy of Pinus edulis and Juniperus osteosperma trees with between 5 and 15% cover and an understory dominated by Pleuraphis jamesii with up to 10% cover. Total vegetation cover is around 30%. Shrubs do not form a layer (<5% total cover), but scattered individuals of Ericameria nauseosa var. juncea (= Chrysothamnus nauseosus var. junceus), Coleogyne ramosissima, Gutierrezia sarothrae, Atriplex confertifolia, Shepherdia rotundifolia, Chrysothamnus viscidiflorus, Ephedra torreyana, and Ephedra viridis are commonly present. The dominant graminoid is Pleuraphis jamesii with lesser amounts of Achnatherum hymenoides, Bouteloua eriopoda, Bouteloua gracilis, Hesperostipa comata, and a variety of forbs with sparse cover.
Dynamics: This association has only been described from Capitol Reef National Park. Until further inventory is completed, there is no global information.
Environmental Description: Stands occur on ridges and hills of eroding pediment surfaces, as well as canyon sides and mesatops on gentle to steep slopes (4-23°) at warmer (south- and west-facing) aspects, and lies between 1411 and 2020 m (4630-6625 feet) in elevation. Boulders, small rocks, and bare ground cover most of the unvegetated surface. Litter and biological soil crusts have sparse to low cover. Soils are rapidly drained loamy sands derived from basalt alluvium, colluvium overlying Moenkopi siltstone, Chinle or Kayenta formations that is occasionally exposed.
Geographic Range: This association has been documented from the high plateaus and Colorado Plateau of Utah, and western Colorado.
