Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is currently described from Great Basin National Park, Nevada. It also occurs in California. Additional global information will be added as it becomes available. This widespread woodland association is known from elevations ranging from 2057-2406 m (6746-7891 feet) on gentle to steep slopes. Sites are variable and range from gullies, low slopes, midslopes, high slopes and toeslopes on all aspects. Substrates include colluvium and alluvium derived from limestone, quartzite, granite and schist. Soils are somewhat well-drained to rapidly drained and composed of sandy loam, loamy sand, silt loam, silty clay, and sandy clay loam. This association is characterized by an open to dense (15-55% cover) canopy dominated by Pinus monophylla or codominated by Juniperus osteosperma. No other canopy associates were documented. The understory is characterized by a subcanopy or shrub layer which may be sparse to somewhat dense ranging from 5-50% cover and dominated by Cercocarpus ledifolius. Numerous other shrubs occur and include Amelanchier utahensis, Artemisia tridentata ssp. vaseyana, Chrysothamnus viscidiflorus, Ephedra viridis, Eriogonum microthecum, Gutierrezia sarothrae, Mahonia repens, Opuntia erinacea, Opuntia polyacantha, Purshia glandulosa, and Symphoricarpos oreophilus. The herbaceous layer is absent to open, not exceeding 25% cover, often without one species occurring as a clear dominant, although the graminoids Poa fendleriana, Elymus elymoides, and Pseudoroegneria spicata may contribute as much as 10% cover in some stands. Forbs are present at very low cover, the most frequent of which are Arabis holboellii, Collinsia parviflora, Descurainia sophia, Lathyrus brachycalyx, Petradoria pumila, Phlox longifolia, and Stephanomeria spinosa.
