G662 Californian North Coastal & Mesic Scrub Group
Type Concept Sentence: This coastal mesic shrubland group is dominated by Baccharis pilularis, Dudleya spp., Erigeron glaucus, Eriogonum parvifolium, Eriophyllum stoechadifolium, Hazardia squarrosa, and/or Plantago maritima. It occurs on sea bluffs and rocky headlands well above the tidal zone throughout rugged portions of the Pacific Coast from Oregon to Baja Norte, Mexico, and including off-shore islands.
Common (Translated Scientific) Name: Californian North Coastal & Mesic Scrub Group
Colloquial Name: Californian North Coastal & Mesic Scrub
Hierarchy Level: Group
Type Concept: These shrublands are dominated by Baccharis pilularis, Dudleya spp., Hazardia squarrosa, Eriogonum parvifolium, Erigeron glaucus, Eriophyllum stoechadifolium, and Plantago maritima. They occur on sea bluffs and rocky headlands well above the tidal zone throughout rugged portions of the Pacific Coast. Plant communities along these often vertical slopes are typically sparse, with many succulents and prostrate shrubs, and species that readily withstand salt spray and saline soils, as well as seasonal drought. Slope instability and erosion result in severe conditions, setting back succession in this group. This group occurs in Oregon, California, Baja Norte, Mexico, and off-shore islands (e.g., Channel Islands).
