Name: Pinus edulis - Juniperus spp. / Leymus salinus Woodland Reference: Western Ecology Working Group of... Description: This woodland association is widespread throughout the Colorado Plateau, but limited to small stands on specific substrates. Stands tend to occupy the tops, shoulders, upper and middle slopes of ridges, as well as canyon sides. These sites range from moderately to steeply sloping (47% to more than 100% slopes), although a minority of stands occur on gentle slopes with gradients not exceeding 10%. Elevations range between 1483 and 2301 m (4865-7550 feet). Stands at higher elevations and latitudes (e.g., Black Canyon of the Gunnison National Park and Dinosaur National Monument) tend to be oriented to the south or west, but stands at lower elevations occur primarily on north or east aspects. Parent materials are variable but generally include a significant element of marine shale, sometimes redeposited with other rocks as alluvium or colluvium. Soils are rapidly drained and include sandy clay loams, clay loams and sandy loams. Total vegetation cover ranges from sparse (7%) to moderate (50%) in this variable community, with drier, more exposed sites supporting less overall plant cover. The canopy may be very open to moderate (5 to 30%), and consists of both <i>Pinus edulis</i> and <i>Juniperus osteosperma</i>. Either tree species may dominate the canopy. Shrubs are generally present but do not provide enough cover to constitute a stratum. Common species include <i>Ephedra viridis, Shepherdia rotundifolia, Opuntia</i> spp., and <i>Chrysothamnus viscidiflorus</i>. The herbaceous layer is more conspicuous than the shrub layer in this community, consisting of a variety of grasses, among which <i>Leymus salinus</i> is clearly dominant. Total herbaceous cover can range from 5% in sparse stands to more than 30% in more sheltered sites. Common associated herbaceous species include <i>Achnatherum hymenoides</i> and <i>Pleuraphis jamesii</i>.  Accession Code: VB.CC.32052.CEGL002340 Plot-observations of this Community Concept: 0
