Sarcobatus vermiculatus / Suaeda moquinii Shrubland
Translated Name: Greasewood / Mojave Seablite Shrubland
Unique Identifier: CEGL001370
Classification Approach: International Vegetation Classification (IVC)
Summary: This shrubland association is reported from the Colorado Plateau and Columbia Basin. Sites are generally flat to gently sloping saline valley bottoms and toeslopes, river floodplains and playas at elevations ranging from 1620 to 1680 m (5315-5500 feet). Soils are deep, saline, alkaline clay loams. The vegetation has a generally sparse shrub layer (<20% cover) that is less than 1.5 m tall and is codominated by Sarcobatus vermiculatus and Suaeda moquinii. The herbaceous layer is sparse.
