Hierarchy Level:  Association

Type Concept: This association is currently described from the Great Basin National Park, Nevada. Additional global information will be added as it becomes available. This woodland association is known from elevations ranging from 2157-2414 m (7080-7920 feet) on moderate to steep slopes. Sites include low to high slopes, ridges and summits on all aspects. Substrates are rocky and composed of colluvium, bedrock, and glacial deposits derived from granite and limestone. This association is characterized by a sparse to open (10-50% cover) canopy dominated by Pinus monophylla and Juniperus osteosperma. Occasionally, Abies concolor or Cercocarpus ledifolius may occur as canopy associates. The understory is characterized by sparse to moderately dense (5-50%) shrub layer dominated by Artemisia tridentata ssp. vaseyana. In some stands Amelanchier utahensis or Ephedra viridis may codominate. Other common shrub associates include Chrysothamnus viscidiflorus, Ericameria nauseosa, Eriogonum microthecum, Gutierrezia sarothrae, Holodiscus dumosus, Mahonia repens, Prunus virginiana, Purshia glandulosa, and Symphoricarpos oreophilus. The herbaceous layer may be very sparse to moderately dense (up 50% cover), the most common dominants being Poa fendleriana and Pseudoroegneria spicata. The exotic Bromus tectorum has invaded many stands and may be the dominant herbaceous species. Forbs are of little importance and no species has high constancy.
