Name:
Quercus chrysolepis / Arctostaphylos viscida Forest
Reference:
NatureServe Biotics 2019
Description:
This forest 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 forest are found on xeric sites at low to mid elevations (490-1890 m [1600-6200 feet]) at the low to upper portions of linear slopes of all aspects. These sites tend to moderately steep to steep (10-36°) with a high level of sun exposure. This association is found on poorly developed, rapidly drained to somewhat poorly drained soils that are mostly shallow but occasionally have medium depths, and textures range from rocky, sandy loam to clay loam that are derived from metamorphic, igneous, granitic parent material. This association is often found on open, rocky slopes with rock outcrops, benches and granite slabs. Litter tends to be high (62-86% cover). Disturbance at these stands is usually low but can be moderate. Stands of this forest usually form a two-story structure with an intermittent to continuous tree layer. This association is dominated by <i>Quercus chrysolepis</i> in the tree layer and <i>Arctostaphylos viscida</i> in the shrub layer. <i>Toxicodendron diversilobum</i> is also commonly found in the shrub layer. A variety of other species are found in this association, although far less common or constant, including <i>Pinus attenuata, Pinus ponderosa, Pinus sabiniana, Pinus coulteri, Quercus wislizeni, Aesculus californica, Arctostaphylos mewukka, Ceanothus cuneatus, Cercis canadensis var. texensis, Chamaebatia foliolosa, Bromus diandrus</i>, and <i>Vulpia myuros</i>. Other species that may be found contributing to minor cover include <i>Pentagramma triangularis, Galium bolanderi, Melica californica, Symphoricarpos mollis, Dryopteris arguta, Rhamnus ilicifolia</i>, and moss.
