Reference:
NatureServe Biotics 2019
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 submesic to xeric sites at low to mid elevations (610-1585 [2000-5200 feet]) on the mid to upper portions of south- to north-facing, linear and convex, moderately steep to somewhat steep slopes. Soils are moderately well-drained to well-drained with textures ranging from loamy sand to sandy loam of igneous, metamorphic, and granitic parent materials. Litter is 40-88% cover. Disturbance is common and includes mostly low and sometimes high impact levels from competition from exotics, logging, grazing, and fire. Stands this shrubland range from 60-90% cover and 2-5 m tall. This association forms a continuous shrub layer dominated by <i>Ceanothus integerrimus</i> and significantly less <i>Arctostaphylos viscida</i> and/or <i>Arctostaphylos mewukka</i>. Often found contributing to minor cover is <i>Pinus ponderosa, Bromus tectorum, Cercocarpus montanus var. glaber, Claytonia perfoliata, Vulpia microstachys, Elymus glaucus, Galium aparine</i>, and <i>Hemizonella minima</i>. Occasionally, <i>Quercus garryana var. fruticosa, Toxicodendron diversilobum</i>, and moss may be common. Other species vary and may include <i>Adenostoma fasciculatum, Aesculus californica, Bromus arenarius, Bromus diandrus, Ceanothus cordulatus, Fragaria vesca, Lepechinia calycina, Potentilla glandulosa, Pteridium aquilinum, Ribes quercetorum</i>, and <i>Staphylea bolanderi</i>.
