Name: Sequoia sempervirens / Notholithocarpus densiflorus / Vaccinium ovatum Forest
Reference: NatureServe Biotics 2019
Description: This forest 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 forest is found on gentle to moderate slopes of all aspects. Stands grow on the middle to upper third of the slope, on moderately fine to medium sandy clay loams. Some soils are derived from Franciscan Melange. Stands are variable in structure not only because of past logging, but also because of environmental effects. Extremely low-statured stands exist on the upper slopes of west-facing canyons coming off of Bolinas Ridge. There <i>Sequoia sempervirens</i> individuals may only be 10-15 m tall, and appear stunted due to restriction by fine-grained mudstone substrate. These stands, adjacent to various chaparral stands, are in contrast to those stands in the canyon bottoms where trees may be up to 80 m tall. This vegetation often forms a two-tiered canopy, with <i>Sequoia sempervirens</i> forming an intermittent to continuous tall-tree canopy between 20 and 80 m, and <i>Notholithocarpus densiflorus</i> important in the lower tree layer. In some stands <i>Umbellularia californica</i> may be equally important. <i>Vaccinium ovatum</i> is the dominant shrub in the open to intermittent shrub layer. <i>Corylus cornuta</i> is often present. The herbaceous layer is open, with <i>Polystichum munitum</i> and <i>Pteridium aquilinum</i> the most common species.
