CEGL003191 Baccharis pilularis - Frangula californica - Rubus parviflorus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Coyotebrush - California Buckthorn - Thimbleberry Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland 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. Stands are found at moderate elevations (samples taken from 435-475 m [1420-1560 feet], but observed as low as 90 m [300 feet]) on gentle southeast-facing slopes. Soil textures range from medium to very fine sandy loam to moderately coarse sandy loam. Most of these stands occur on ridges within the summer fog belt and may receive substantial additional moisture from fog drip. Stands of this shrubland form an open herb layer and an open to continuous shrub layer. It is dominated by Baccharis pilularis, Frangula californica, and Rubus parviflorus. Scrophularia californica, Rubus ursinus, Heracleum maximum, Pteridium aquilinum, Clinopodium douglasii, Vaccinium ovatum, and Toxicodendron diversilobum are usually also present. Other species that may be present are Ceanothus palmeri, Diplacus aurantiacus, and Polystichum munitum.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This is a late-seral stage of ~Baccharis pilularis Scrub Alliance (A0836)$$. Notes for the sample plots suggested that these stands had not been disturbed for many years. This is also in keeping with the model of Baccharis transition states into a Frangula californica alliance in moist foggy coastal areas of the study area.
