Soils are moderately fine sandy clay loams, sometimes derived from Franciscan Melange parent materials. This forest forms a two-tiered canopy with <i>Pseudotsuga menziesii</i> dominating the upper canopy. which is intermittent to continuous and generally more than 30 m in height. <i>Quercus agrifolia</i> or <i>Umbellularia californica</i> may dominate the lower tree canopy, though <i>Umbellularia californica</i> is not present in all stands. The shrub layer can be open to intermittent and is highly variable. <i>Corylus cornuta</i> is often present, as are <i>Toxicodendron diversilobum, Rubus ursinus</i>, and/or <i>Rubus parviflorus</i>. The herbaceous layer is open to continuous, and often contains <i>Clinopodium douglasii, Stachys ajugoides, Maianthemum stellatum, Iris douglasiana, Sanicula crassicaulis</i>, and/or <i>Erechtites minimus</i>. <i>Dryopteris arguta</i> is important in some stands.
