Common (Translated Scientific) Name: Giant Chinquapin / California Huckleberry Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is currently only known from Point Reyes National Seashore and Golden Gate National Recreation Area in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association is found on gentle to moderate slopes on all aspects. Stands are found on upper slopes and ridges. Soils recorded are fine, sandy loams. Most stands appear to occupy relatively fine-grained substrates derived from marine sedimentary rocks. Stands are relatively small and occupy upper thirds of ridges and ridgetops where soils are shallow and rocky. Adjacent vegetation includes stands of Arctostaphylos nummularia, Pseudotsuga menziesii, Sequoia sempervirens, and Adenostoma fasciculatum. The associated shrubby alliance stands occupy the poorest soils, while the tree alliances occupy the better developed soils of the adjacent north-facing slopes and ravines. Most of the Chrysolepis chrysophylla stands are near the upper level of average summer fog and are intermediate in soil development between chaparral and forest. They appear to occupy a narrow interface between forest and chaparral usually forming small stands less than 2 ha in size. Chrysolepis chrysophylla var. minor forms an open to continuous tall-shrub or short-tree canopy 5-10 m in height. Scattered individuals of other evergreen tree species may be present including Sequoia sempervirens and/or Pseudotsuga menziesii. Vaccinium ovatum is conspicuous in the shrub layer with 35-90% cover. Toxicodendron diversilobum, Baccharis pilularis, Arctostaphylos glandulosa, Quercus wislizeni, and/or Quercus berberidifolia may also be present. The herbaceous layer is fairly sparse, but usually contains Pteridium aquilinum. Xerophyllum tenax and Pickeringia montana are occasional associates.

Geographic Range: This association is only known from the vicinity of the Point Reyes National Seashore and Golden Gate National Recreation Area. Information about its global range is not available without additional inventory. Similar Chrysolepis chrysophylla var. minor stands have been noted in the Santa Cruz Mountains (Hecht et al. 1973). However, any vegetation similar to this association appears to be limited to the Outer Coast Ranges of California in the vicinity of San Francisco Bay (Keeler-Wolf pers. obs. 1973-1999).
