Name: Juniperus osteosperma / Artemisia tridentata ssp. tridentata Woodland Reference: NatureServe Biotics 2019 Description: This woodland association occurs locally on benches, alluvial terraces, plateaus and draws in northwestern Colorado, eastern Utah, Arizona, California and Idaho. Elevations range from 1255-1860 m. Sites are located on gentle to moderate slopes, and tend to occupy relatively cool microsites, either on north aspects or cold-air drainages. Stands of this association tend to develop in <i>Artemisia tridentata ssp. tridentata</i> shrublands that have escaped disturbance for a long enough time to allow <i>Juniperus osteosperma</i> trees from nearby woodlands to invade. Soils are deep and generally are derived from alluvium. The best-developed stands occur on canyon floors where terraces are protected from flooding. The tree canopy is generally open, with between 10 and 50% cover by <i>Juniperus osteosperma</i>. <i>Artemisia tridentata ssp. tridentata</i> often has equal or greater cover than the tree layer, and shrubs may be 2 m high. If other shrubs are present, it is with low cover; species reported include <i>Amelanchier utahensis, Ericameria nauseosa, Atriplex canescens, Opuntia</i> spp., and <i>Gutierrezia sarothrae</i>. The herbaceous layer is diverse and well-developed in stands that have been protected from grazing, and may be dominated by grasses such as <i>Bouteloua gracilis, Hesperostipa comata</i>, or <i>Distichlis spicata</i>. However, most stands have experienced a long history of grazing, and in these cases, the herbaceous layer is generally dominated by exotic <i>Bromus tectorum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31268-{3AA015EE-AEB1-4754-AD2F-55CDF31490F7} Plot-observations of this Community Concept: 0
