Common (Translated Scientific) Name: Douglas-fir / California Live Oak Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 grows on the lower to middle third of moderate to steep slopes. Aspects are generally south-southeast. Soils are moderately fine sandy clay loams, sometimes derived from Franciscan Melange parent materials. This forest forms a two-tiered canopy with Pseudotsuga menziesii dominating the upper canopy. which is intermittent to continuous and generally more than 30 m in height. Quercus agrifolia or Umbellularia californica may dominate the lower tree canopy, though Umbellularia californica is not present in all stands. The shrub layer can be open to intermittent and is highly variable. Corylus cornuta is often present, as are Toxicodendron diversilobum, Rubus ursinus, and/or Rubus parviflorus. The herbaceous layer is open to continuous, and often contains Clinopodium douglasii, Stachys ajugoides, Maianthemum stellatum, Iris douglasiana, Sanicula crassicaulis, and/or Erechtites minimus. Dryopteris arguta is important in some stands.
