Name: Pseudotsuga menziesii - Sequoia sempervirens / Polystichum munitum Forest Reference: Western Ecology Working Group of... Description: This giant conifer forest is found near the northern distributional limit of Sequoia sempervirens. Sequoia sempervirens and Pseudotsuga menziesii 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 degrees). 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 Sequoia sempervirens tend to be highly scattered except in the most moist sites where it is dominant to Pseudotsuga menziesii. Sequoia sempervirens often supports most of the basal area on a site. Tsuga heterophylla very rarely codominates. Shrub cover is variable (10-80%) and consists primarily of Vaccinium ovatum. Herb cover varies from 30-70% and is most often characterized by Oxalis oregana, Trillium ovatum, Polystichum munitum, and Galium spp. Other tree species which may be common are Umbellularia californica, Alnus rubra, Lithocarpus densiflorus, and Acer macrophyllum, which when present form a secondary canopy below the giant conifers. Occasionally, this type occurs in a matrix with Pseudotsuga menziesii - Sequoia sempervirens / Rhododendron macrophyllum / Vaccinium ovatum Forest (CEGL000082).  Accession Code: VB.CC.20032.PSEUDOTSUGAMENZ Plot-observations of this Community Concept: 0
