Name: A.840
Reference: EcoArt 2002
Description: This shrubland alliance is found on alluvial terraces, flats and sand bars in central and south-central Arizona. Stands are restricted to the corridors of intermittent drainages and floodplains from 670-1070 m in elevation. Soils are generally sandy, frequently with many cobbles and boulders. These relatively mesic shrublands utilize moisture from the water table and are dependent on intermittent flooding of washes to supplement the soil moisture and maintain the ground water levels. Stands are typically a dense thicket (60-80% canopy cover) of deciduous shrubs and trees up to 4 m tall. The dominant diagnostic species is the microphyllous shrub ~Baccharis sarothroides$, which grows up to 2 m. Codominants may include two tall-shrub/tree species, ~Parkinsonia microphylla$ and ~Prosopis glandulosa$, and the shrub ~Baccharis salicifolia$. Other associated woody species include ~Populus$ spp., ~Chilopsis linearis, Quercus turbinella, Celtis pallida, Acacia greggii$, and ~Ambrosia ambrosioides$. The herbaceous layer is sparse, but may include ~Mentzelia multiflora, Polanisia dodecandra ssp. trachysperma, Eriogonum$ spp., and ~Sporobolus$ spp.
