CEGL003190 Baccharis pilularis - Eriophyllum stoechadifolium Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Coyotebrush / Seaside Woolly-sunflower Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: Stands of this shrubland association occupy a narrow coastal strip with relatively small total area, from south-central to north-central California. The characteristic species, Eriophyllum stoechadifolium, is largely restricted to bluffs and slopes within a short distance of the open ocean coast. Stands are commonly exposed to strong onshore winds and are often bathed in fog by salt-laden winds much of the year. Stands of this shrubland vary in structure forming an open to intermittent herb layer. Average total vegetation cover is 85%. This association is dominated by Baccharis pilularis and Eriophyllum stoechadifolium and includes Clinopodium douglasii, Pteridium aquilinum, Diplacus aurantiacus, Erigeron glaucus, Rubus ursinus, Toxicodendron diversilobum, and Holcus lanatus. It may also include Fragaria chiloensis, Frangula californica, and Artemisia californica.

Floristics: Stands of this shrubland vary in structure forming an open to intermittent herb layer of 2-60% cover at 0-25 cm tall, 11-30% cover at 25-50 cm tall 15-35% at 0.5-1 m tall and 0-90% cover at 1-2 m tall. Average total vegetation cover is 85%. This association is dominated by Baccharis pilularis and Eriophyllum stoechadifolium and includes Clinopodium douglasii (= Satureja douglasii), Pteridium aquilinum, Diplacus aurantiacus (= Mimulus aurantiacus), Erigeron glaucus, Rubus ursinus, Toxicodendron diversilobum, and Holcus lanatus. It may also include Fragaria chiloensis, Frangula californica (= Rhamnus californica), and Artemisia californica.

Environmental Description:  This association is a coastward expression of ~Baccharis pilularis Scrub Alliance (A0836)$$. The characteristic species, Eriophyllum stoechadifolium, is largely restricted to bluffs and slopes within a short distance of the open ocean coast. Stands are commonly exposed to strong onshore winds and are often bathed in fog by salt-laden winds much of the year.
Geographic Range: This association is only known from the Point Reyes National Seashore. Information about its global characteristics is not available without additional inventory. It was described from the northern coast of California by Baxter (1992) and reported by Sawyer and Keeler-Wolf (1995). This association has been identified as far south as Monterey County, but Marin County appears to be its northern limit (T. Keeler-Wolf pers. obs.).
