Common (Translated Scientific) Name: Coyotebrush / Powdery Live-forever 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 low elevations on the mid to upper third of southeast- to southwest-facing slopes (31-45°). Soil textures range from fine silty clay to sand and are of shale or conglomerate parent material. Stands are immediately adjacent to the coast on bluffs of sedimentary rock or on sand dunes and sandsheets that have been blown up on headlands from prevailing onshore salt-laden winds. Stands of this shrubland form an intermittent to continuous herb layer and a short-shrub layer of less than 0.5 m tall. This association is dominated by Baccharis pilularis in its low prostrate form (formerly known as Baccharis pilularis var. pilularis) and characterized by the succulent rosette herb Dudleya farinosa. The stands also include the low shrubs Eriophyllum stoechadifolium and Lupinus arboreus, and a number of herbaceous species, including Vulpia sp., Bromus carinatus, Carpobrotus edulis, Bromus diandrus, Hypochaeris radicata, Lolium perenne, and Plantago erecta, which contribute to minor cover. A variety of other species may be found in this association including Iris douglasiana, Nassella pulchra, Chlorogalum pomeridianum, Elymus glaucus, Erigeron glaucus, Fragaria chiloensis, Pinus radiata, Phacelia californica, Anagallis arvensis, Eriogonum latifolium, Festuca rubra, and Grindelia stricta. This association is often found adjacent to disturbed grassland associations, but may also occur near denser, taller associations of the ~Baccharis pilularis Scrub Alliance (A0836)$$, in particular ~Baccharis pilularis - Eriophyllum stoechadifolium Shrubland (CEGL003190)$$.
