Name: Pinus edulis - Juniperus osteosperma / Artemisia bigelovii Woodland Reference: Western Ecology Working Group of... Description: This association is found in western Colorado and eastern Utah, usually on mesa tops and canyon rims. Sites can have gentle to steep slopes and with varying local aspects but have been most commonly observed on sites whose general aspect is north or east. This association has been found at sites between 1476 and 2104 m (4840-6900 feet) elevation and mostly on sandstone. Soils are shallow, well-drained to rapidly drained loamy sands, sandy loams, or silt loams. The unvegetated ground surface is typically composed of litter, bedrock, and bare soil. This woodland association generally has sparse to moderate total vegetation cover. There is an open tree canopy 2-5 m tall dominated by <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> with 2-20% cover each. The shrub layer is also open and, besides the abundance of <i>Artemisia bigelovii</i>, is usually mixed in composition. <i>Artemisia bigelovii</i> is the most abundant shrub with 2-10% cover. Other typical shrubs are <i>Echinocereus triglochidiatus, Ephedra torreyana, Ephedra viridis, Eriogonum corymbosum, Fraxinus anomala</i> (which can be present in the tree canopy, as well), and <i>Gutierrezia sarothrae</i>. The herbaceous layer typically has less than 5% cover and contains graminoid species such as <i>Achnatherum hymenoides, Elymus elymoides</i>, and <i>Pleuraphis jamesii</i> and forbs such as <i>Arenaria fendleri, Erodium cicutarium, Heterotheca villosa</i>, and <i>Tetraneuris acaulis</i>.  Accession Code: VB.CC.32047.CEGL002118 Plot-observations of this Community Concept: 0
