Name: Pinus sabiniana - Quercus wislizeni / Arctostaphylos viscida Woodland Reference: Western Ecology Working Group of... Description: This woodland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this woodland are found at xeric sites at low elevations (550-1370 m [1800-4500 feet]) on the low to upper portions of southwest- to north-facing slopes at higher elevations. Slopes are convex-, concave- and linear-shaped and vary from gentle to steep. Soils tend to be poorly developed and rocky in places with textures ranging from loamy sand to clay loam and of metamorphic and igneous, granitic parent material. Litter ranges from 60-75% cover. Fire is common and can cover extensive areas. Impact from the invasion of exotic species can be high. This association forms an open to intermittent tree layer dominated by <i>Pinus sabiniana</i> and <i>Quercus wislizeni</i> with an intermittent understory shrub layer dominated by <i>Arctostaphylos viscida</i>. Other species contributing to minor cover varies and may include <i>Toxicodendron diversilobum, Aira caryophyllea, Bromus hordeaceus, Bromus diandrus, Cercis canadensis var. texensis, Eriodictyon californicum</i>, lichen, moss, <i>Rhamnus ilicifolia (= Rhamnus crocea ssp. ilicifolia), Rhus trilobata, Cheilanthes gracillima</i>, and <i>Ceanothus cuneatus</i>. <i>Ceanothus fresnensis</i> is a rare species that may occur within this association. The stands are usually relatively open, but are variable, and may range from a woodland condition to a sparsely wooded herbaceous or shrubland condition.  Accession Code: VB.CC.31187.CEGL008636 Plot-observations of this Community Concept: 0
