Sites are generally flat to gently sloping and moderately saline, but the alliance also occurs on rolling to hilly fans and slopes. Other environmental characteristics vary by site and region. The vegetation included in this alliance is characterized by a sparse to moderately dense shrub layer dominated or codominated by ~Atriplex polycarpa$. Shrub associates may include ~Larrea tridentata, Ambrosia dumosa, Eriogonum fasciculatum, Hymenoclea salsola, Atriplex canescens, Atriplex confertifolia, Gutierrezia sarothrae$, and ~Suaeda moquinii$. Perennial graminoids are present to abundant in some habitats and may include ~Distichlis spicata, Pleuraphis mutica (= Hilaria mutica)$, and ~Sporobolus$ spp. Exotic annual grasses dominate the understory in some stands.
