Hierarchy Level: Association
Type Concept: This association has only been described from Zion National Park, Utah. Additional global information will be added as it becomes available. Ephedra nevadensis dominates this association with cover of 30%. Gutierrezia sarothrae, Atriplex canescens, and Echinocereus engelmannii are present but contribute minimal cover. The herbaceous layer is normally very sparse. This stand of Ephedra nevadensis occurs on a basalt outcrop at 1250 m (4100 feet). The slope is gentle with a southerly aspect. Exposed soils are minimal and have clay loam texture. Most of soil is covered with small and large lava rocks.
