Name: Baccharis pilularis - Holodiscus discolor Shrubland
Reference: NatureServe Biotics 2019
Description: This shrubland association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands are found at low elevations (58-295 m [190-962 feet]) on 16° to 31° slopes with southeast to north-northwest aspects. This association is found on the middle third to the entire convex to concave slopes. Soil textures range from medium to very fine sandy loam to moderately coarse, sandy loam from sandstone. This is a mesophytic association that, if found on southerly exposures, is usually found on concave slopes. Stands of this shrubland vary in structure from less a meter to 2-5 m tall. This association is dominated by <i>Baccharis pilularis</i> and <i>Holodiscus discolor</i> and usually includes <i>Toxicodendron diversilobum, Frangula californica, Rubus ursinus</i>, and <i>Diplacus aurantiacus</i>. <i>Festuca rubra</i> may be a common grass, and <i>Quercus agrifolia</i> may also be very common as a low wind-swept shrub. A variety of other species may be found including <i>Corylus cornuta, Festuca californica, Lonicera hispidula, Eriophyllum stoechadifolium, Heracleum maximum, Stachys bullata, Umbellularia californica, Symphoricarpos mollis, Clinopodium douglasii</i>, and <i>Pteridium aquilinum</i>. This association appears to occur adjacent to wooded or forested alliance stands and may represent the transition between the ~<i>Baccharis pilularis</i> Scrub Alliance (A0836)$$ and various coastal forests of <i>Quercus agrifolia, Umbellularia californica</i>, and <i>Pseudotsuga menziesii</i>. Such common shrubs in this association as <i>Corylus cornuta</i> and <i>Holodiscus discolor</i> are also common associates of these forest alliances. Many individuals of the aforementioned trees are stunted in these stands, the result of salt-laden winds.
