Name: Pseudotsuga menziesii / Umbellularia californica / Polystichum munitum 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 association grows on the middle to upper third of moderate slopes. Aspects are mostly north and east. Stands are found in the inland valleys and prefer medium to fine silt or sandy loams. This forest forms a two-tiered canopy with <i>Pseudotsuga menziesii</i> dominating the upper canopy. The top tier is intermittent, and generally less than 35 m in height. The lower tree canopy is dominated by <i>Umbellularia californica</i>, though <i>Notholithocarpus densiflorus, Quercus agrifolia</i>, and/or <i>Aesculus californica</i> may provide minor cover. The shrub layer is open with only minor cover contributed by <i>Vaccinium ovatum, Frangula californica ssp. californica, Rubus ursinus</i>, and/or <i>Rubus parviflorus</i>. <i>Polystichum munitum</i> is the dominant understory species. Other common herbaceous associates may include <i>Pteridium aquilinum, Iris douglasiana</i>, and/or <i>Stachys ajugoides</i>. Generally this is a more mesic forest than ~<i>Pseudotsuga menziesii / Umbellularia californica / Frangula californica ssp. californica</i> Forest (CEGL003167)$$. It occurs on concave slopes or on more northerly aspects than that association.
