Description: Stands of this central and southern California alliance are found in areas of coastal sand accumulation, on partially stabilized backdune slopes of sand bars, ridges, flats, river mouths, and spits along the coastline. Typically they occur farther from the coast than foredunes. This coastal region has a strongly maritime climate, characterized by low average annual precipitation, ranging from 34 cm at San Francisco to less than 25 cm at San Diego. A very high percentage of this precipitation falls during the fall and winter months as rain, while summers are typically warm and dry. Winter temperatures are mild. Persistent onshore winds and salt spray are important factors. Soils are well-drained sands, with low organic matter and nutrients. A mix of broad-leaved evergreen shrubs and subshrubs dominates this dune scrub alliance, typically less than 1 m tall. Species commonly present can include ~Lupinus chamissonis, Ericameria ericoides, Artemisia pycnocephala, Artemisia californica, Ephedra californica, Isocoma menziesii$, and the stem succulent (cactus) ~Opuntia littoralis$. The canopy of this low-shrub layer can be quite dense and continuous or intermittent to open. Species composition varies somewhat from northern to southern stands. The taller, broad-leaved deciduous shrub ~Rhus integrifolia$ may be present as an emergent. The herbaceous component may be abundant or sparse.
