CEGL003193 Baccharis pilularis - Lupinus (arboreus, chamissonis) Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Coyotebrush - (Yellow Bush Lupine, Chamisso Bush Lupine) 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 flat to 21° slopes of dunes, plains, and mid third of slopes facing southwest to south-southwest. Soil textures range from medium sand of sand dunes to shale. Most stands are on dunes or sandsheets near the immediate coast. They often occupy the so-called "backdune" scrub areas near the interface of upland terraces and bluffs and the dune vegetation. Stands of this shrubland form an open to intermittent herb layer and an open to intermittent shrub layer 1-2 m tall. Average overall cover is 55%. This shrubland association is dominated by Baccharis pilularis and Lupinus arboreus. Bromus diandrus, Pteridium aquilinum, and Vulpia sp. are also found in this association, although they contribute minor cover. Various other species may also contribute minor cover, including Poa douglasii, Cardionema ramosissimum, Eriogonum latifolium, Eschscholzia californica, Rubus ursinus, Bromus maritimus, Marah fabaceus, Carpobrotus edulis (exotic), Claytonia perfoliata, Lotus scoparius, Dudleya farinosa, Melica imperfecta, Osmorhiza berteroi, Toxicodendron diversilobum, Polypodium californicum, and Leymus triticoides. This association is often adjacent to beach communities. Lupinus arboreus is a short-lived perennial, which may or may not be present in the stands in vegetative form. Lupinus chamissonis is rarely the dominant but is present in most examples.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Lupinus arboreus is an introduced species from Point Reyes north (Pickart and Sawyer 1998), which may or may not occur on sandy substrates, while Lupinus chamissonis is largely restricted to sand and is common from Oregon to southern California.
