Name: Quercus vacciniifolia - Arctostaphylos patula Shrubland Reference: Western Ecology Working Group of... Description: This shrubland association is currently only known from Yosemite National Park and granitic substrates in the Klamath Mountains within Siskiyou and Trinity counties, California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands at Yosemite are found at mid elevations (2130-2590 m [7000-8500 feet]) on flat to steep (0-36°) slopes. Aspects range from northeast to west but are often northeast, east and southeast. This association is found on sites with often poorly developed soils with textures ranging from rocky to rocky gravelly loam. Soils are well-drained to poorly drained and shallow to moderately deep. Parent material is granitic. In the Klamath Mountains, this association occurs on south- and southwest-facing exposures on open granitic slopes between 1525 and 2135 m (5000-7000 feet) elevation. Stands form an intermittent to continuous shrub layer dominated by <i>Quercus vacciniifolia</i> and <i>Arctostaphylos patula</i>. <i>Pinus jeffreyi, Abies concolor</i>, and <i>Abies magnifica</i> are occasionally present in the sparse overstory. <i>Ceanothus cordulatus, Prunus emarginata, Arctostaphylos nevadensis</i>, and <i>Garrya fremontii</i> are often found in the shrub layer. Other shrub species that may be present include <i>Chrysolepis sempervirens</i> and <i>Ceanothus integerrimus (= var. californicus)</i>. A variety of herbaceous species found contributing to low cover might include <i>Achnatherum speciosum, Amelanchier utahensis, Arabis</i> sp., <i>Gayophytum diffusum, Juncus parryi, Leptodactylon pungens, Penstemon azureus, Penstemon newberryi, Streptanthus tortuosus</i>, and <i>Symphoricarpos rotundifolius</i>.  Accession Code: VB.CC.32592.CEGL008697 Plot-observations of this Community Concept: 0
