Name: Juniperus osteosperma / Cercocarpus intricatus Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs on steep, rocky ridges in the Great Basin of Nevada, whereas in the Colorado Plateau of Utah and Colorado it occupies gentle to moderate slopes on mesas, benches and canyon floors where bedrock is partially covered by sandy soils. Stands are located between 1500 and 1980 m (4920-6500 feet) elevation. Aspect may influence the distribution of stands locally, but rangewide stands may occur on any aspect. At least half the unvegetated surface is bare ground or sandstone slickrock, with the remainder divided primarily between litter and biological soil crusts. Soils are shallow or skeletal and are rapidly drained sands or sandy loams. Total vegetation cover rarely exceeds 35% because the high exposure of rock limits where plants can grow. The canopy is open, with <i>Juniperus osteosperma</i> trees providing between 5 and 25% cover; the trees are often stunted. There is a well-developed shrub layer in which <i>Cercocarpus intricatus</i> is dominant or codominant. Total shrub cover ranges from 5 to 15%. Associated shrubs include <i>Amelanchier utahensis, Fraxinus anomala, Artemisia bigelovii, Glossopetalon spinescens var. meionandrum, Atriplex confertifolia, Cercocarpus montanus, Chrysothamnus greenei, Philadelphus microphyllus, Symphoricarpos longiflorus</i>, and <i>Ephedra viridis</i>. The herbaceous layer is diverse in terms of species composition and provides sparse to low cover. Graminoids commonly include <i>Aristida purpurea, Achnatherum hymenoides, Hesperostipa</i> and/or <i>Achnatherum</i> spp. (= <i>Stipa</i> spp.), and <i>Muhlenbergia pungens</i>. Forbs are diverse but provide sparse cover; <i>Stenotus acaulis (= Haplopappus acaulis)</i> occurs throughout the range.  Accession Code: VB.CC.33709.CEGL000733 Plot-observations of this Community Concept: 0
