CEGL003164 Pinus muricata - Arbutus menziesii / Vaccinium ovatum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bishop Pine - Pacific Madrone / California Huckleberry 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 association grows on gentle to moderate slopes on northern and eastern exposures. Stands are typically found on the middle third of the slope. Soils are moderately fine to coarse sandy clay loams. Pinus muricata is the dominant tree in the canopy, usually with small amounts of Arbutus menziesii. Individuals of Quercus agrifolia, Umbellularia californica, and/or Chrysolepis chrysophylla var. chrysophylla may be present. The canopy is intermittent to continuous and is typically less than 20 m but occasionally up to 30 m in height. Vaccinium ovatum is important to dominant in the shrub canopy. The shrub layer is sparse to intermittent. Corylus cornuta or Frangula californica ssp. californica are often present and sometimes dominate the shrub layer. Notholithocarpus densiflorus may also be important. The herbaceous layer is sparse but may contain Polystichum munitum, Pteridium aquilinum, Rubus ursinus, Gaultheria shallon, Clinopodium douglasii, and/or Lonicera hispidula.

Environmental Description: This association grows on gentle to moderate slopes on northern and eastern exposures. Stands are typically found on the middle third of the slope. Soils are moderately fine to coarse sandy clay loams.
Geographic Range: This association is only known from the vicinity of the Point Reyes National Seashore. Information about its global characteristics is not available without additional inventory. Because Pinus muricata stands are spotty and restricted to California, it is likely that only a few other localities for this association may exist. One possible location is the vicinity of Salt Point State Park in Sonoma County.
