Name: Pseudotsuga menziesii - Sequoia sempervirens / Polystichum munitum Forest
Reference: NatureServe Biotics 2019
Description: This giant conifer forest is found near the northern distributional limit of <i>Sequoia sempervirens</i>. <i>Sequoia sempervirens</i> and <i>Pseudotsuga menziesii</i> dominate the tall canopy of these coastal fog-belt forests. This association occurs on intermediate to mesic sites, usually with a northern or eastern aspect. Slopes are relatively low (5-10°). Tree cover is 55-75%. Soils are fine-textured, with good moisture-holding capacity, well-drained and relatively deep, derived from silt or sandstone. Individuals of <i>Sequoia sempervirens</i> tend to be highly scattered except in the most moist sites where it is dominant to <i>Pseudotsuga menziesii</i>. <i>Sequoia sempervirens</i> often supports most of the basal area on a site. <i>Tsuga heterophylla</i> very rarely codominates. Shrub cover is variable (10-80%) and consists primarily of <i>Vaccinium ovatum</i>. Herb cover varies from 30-70% and is most often characterized by <i>Oxalis oregana, Trillium ovatum, Polystichum munitum</i>, and <i>Galium</i> spp. Other tree species which may be common are <i>Umbellularia californica, Alnus rubra, Notholithocarpus densiflorus</i>, and <i>Acer macrophyllum</i>, which when present form a secondary canopy below the giant conifers. Occasionally, this type occurs in a matrix with ~<i>Pseudotsuga menziesii - Sequoia sempervirens / Rhododendron macrophyllum / Vaccinium ovatum</i> Forest (CEGL000082)$$.
