Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Laurel / Western Swordfern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is known from the vicinity of the San Francisco Bay area including Alameda, Marin, Contra Costa, and San Mateo counties, California. It is possible that this association continues farther north and south in the outer Coast Ranges of California. This association is a relatively mesic type that occupies ravine bottoms or north- or northeast-facing slopes in the San Francisco Bay Area. Stands may occupy slopes up to 45% steep and are usually found on marine sediments including soils derived from the Franciscan Formation. This association as seen in the Berkeley and Oakland Hills is composed of a dense canopy of up to 95% cover of single- to multi-stemmed individuals of Umbellularia californica from 12 to 20 m tall with a sparse shrub and sapling layer of various species including Corylus cornuta, Symphoricarpos mollis, and Ribes malvaceum. The herbaceous layer is dominated by open to dense clumps of Polystichum munitum estimated as covering from 15 to 80% of the ground.
