Name: Adenostoma fasciculatum Sierran Chaparral Shrubland Reference: Western Ecology Working Group of... Description: This shrubland 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. It is likely that this association is widespread in the Sierra Nevada foothills and perhaps elsewhere in California. Stands are found at extremely xeric sites at low elevations (520-1100 m [1700-3600 feet]) on the mid-portions of southeast- to southwest-facing, undulating and linear, moderately steep to steep slopes. This association generally occurs in hotter, drier sites such as mid to high slopes, ridgetops, and southwestern slopes off spur ridges and granitic intrusions. Soils tend to be moderately well-developed and somewhat stony with textures ranging from loamy sand to clay loam from igneous, granitic, metamorphic, and gneiss parent materials. Soils are rapidly to moderately well-drained. Litter cover ranges from 5-40% cover. The amount of bare soil is high and ranges from 5-40% cover. Impact from disturbance is low to high and often includes invasion from exotic species. Stands of this shrubland form a two-story structure with a continuous shrub layer dominated by <i>Adenostoma fasciculatum</i> that often occurs with <i>Ceanothus cuneatus</i>. Pure stands of <i>Adenostoma fasciculatum</i> are usually observed in slightly hotter environments. The understory herb layer is typically open. Occasionally common in this association are <i>Eriodictyon californicum</i> and cryptogamic crust. Other species that may also be found contributing to minor cover vary but may include <i>Vulpia myuros, Eriophyllum confertiflorum, Aira caryophyllea, Bromus hordeaceus, Daucus pusillus, Erodium cicutarium, Galium parisiense, Hypochaeris glabra, Pentagramma triangularis</i>, and <i>Trifolium microcephalum</i>. <i>Eriophyllum congdonii</i> is a rare species that may be found contributing to minor cover in this association.  Accession Code: VB.CC.34712.CEGL005816 Plot-observations of this Community Concept: 0
