Name: Toxicodendron diversilobum - Baccharis pilularis - Rubus parviflorus 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. This association is found on the upper third of moderate slopes. Aspects are north to east and slopes are often concave. Soil textures can vary from medium silty loams to moderately coarse sandy loams. This association is a mesic expression of the "North Coastal Scrub" where <i>Toxicodendron diversilobum</i> is strongly dominant. It is clearly related to other <i>Baccharis pilularis</i> associations and with further investigation may be considered a phase of that alliance. Vegetation within this association includes stands dominated by <i>Toxicodendron diversilobum</i> with significant amounts of <i>Baccharis pilularis</i> and <i>Rubus parviflorus</i> or <i>Rubus ursinus</i> in the shrub layer. The shrub canopy is fairly continuous and between 1-2 m in height. Emergent, shrubby individuals of <i>Pseudotsuga menziesii</i> are often present. <i>Marah fabaceus</i> is usually present at about 1% cover. Species present in the herbaceous layer may include <i>Scrophularia californica, Sanicula crassicaulis, Pteridium aquilinum, Phacelia californica</i>, and/or <i>Maianthemum stellatum</i>.
