Name: Ceanothus cordulatus / Sparse Understory Sierran 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. Stands are found at mid elevations (1675-2195 m [5500-7200 feet]) on the mid to upper portions of gentle to steep slopes (3-31°). This association is found on all aspects of linear or convex-shaped slopes. Soils are formed on a granitic substrate and are moderately well-developed with textures that range from loamy gravelly sand to clay loam. These sites are well-drained to poorly drained with soil depths ranging from moderately deep to deep. Fire is common in this association, and litter cover can be high in stands where there has not been recent fire. This is often associated with canopy openings of <i>Abies concolor</i> in postburn communities. Stands of this shrubland form an intermittent to continuous shrub layer dominated by <i>Ceanothus cordulatus</i>. Tree species are occasionally present and may include <i>Abies concolor, Calocedrus decurrens, Pinus lambertiana, Pinus ponderosa</i>, and <i>Quercus kelloggii</i>; however, these are often in the shrub layer and contribute to minor cover. <i>Arctostaphylos patula</i> is usually found in the shrub layer. Occasional shrubs include <i>Ribes roezlii (= Grossularia roezlii), Chrysolepis sempervirens</i>, and <i>Ceanothus parvifolius</i>. <i>Ceanothus cuneatus, Prunus emarginata</i>, and <i>Prunus virginiana var. demissa</i> can be common in some stands. The herbaceous layer is open and may include <i>Gayophytum diffusum, Hackelia velutina, Bromus tectorum</i>, and <i>Lupinus</i> sp.  Accession Code: VB.CC.33969.CEGL005821 Plot-observations of this Community Concept: 0
