Name: Baccharis pilularis - Holodiscus discolor Shrubland Reference: Western Ecology Working Group of... 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-degree 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 (= Rhamnus californica), Rubus ursinus</i>, and <i>Diplacus aurantiacus (= Mimulus 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 (= Heracleum lanatum), Stachys bullata, Umbellularia californica, Symphoricarpos mollis, Clinopodium douglasii (= Satureja 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> Shrubland 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.  Accession Code: VB.CC.34394.CEGL003192 Plot-observations of this Community Concept: 0
