Common (Translated Scientific) Name: Greasewood - Saltbush species Alkaline-Saline Wet Scrub Group
Colloquial Name: North American Desert Alkaline-Saline Wet Scrub
Hierarchy Level: Group
Type Concept: This group occurs throughout much of the western U.S. in intermountain basins. Stands typically occur near drainages on stream terraces and flats or may form rings around more sparsely vegetated playas. Sites typically have saline soils, a shallow water table and flood intermittently, but remain dry for most growing seasons. The water table remains high enough to maintain vegetation, despite salt accumulations. This group consists of open to moderately dense shrublands dominated by Atriplex lentiformis, Atriplex parryi, Atriplex polycarpa, Atriplex spinifera, Allenrolfea occidentalis, Salicornia rubra, Sarcobatus vermiculatus, Sesuvium verrucosum, and/or Suaeda moquinii. Stands may be monotypic or have lesser abundance of other shrubs such as Atriplex canescens, Atriplex confertifolia, Atriplex gardneri, Artemisia tridentata ssp. wyomingensis, Artemisia tridentata ssp. tridentata, Artemisia cana ssp. cana, Baccharis spp., Krascheninnikovia lanata, and others. The herbaceous layer, if present, is usually dominated by graminoids. There may be inclusions of Calamovilfa longifolia, Distichlis spicata (where water remains ponded the longest), Eleocharis palustris, Pascopyrum smithii, Poa pratensis, Puccinellia nuttalliana, or Sporobolus airoides herbaceous types.
Diagnostic Characteristics: Salt-tolerant shrublands with a shallow water table.

Similar NVC Types:
G538 North American Desert Alkaline-Saline Marsh & Playa, note: includes salt communities in the cold desert that are dominated by herbaceous species.
G534 Western Great Plains Saline Wet Meadow, note: occurs in the northern and western Great Plains and is also dominated by Sarcobatus vermiculatus with more Great Plains herbaceous species.
Physiognomy and Structure: Shrubland.
Floristics: These shrublands are dominated by Atriplex lentiformis, Atriplex parryi, Atriplex polycarpa, Atriplex spinifera, Allenrolfea occidentalis, Salicornia rubra, Sarcobatus vermiculatus, Sesuvium verrucosum, and/or Suaeda moquinii. Codominant shrubs include Ambrosia dumosa, Artemisia californica, Atriplex canescens, Baccharis pilularis, Baccharis salicifolia, Encelia californica, Eriogonum fasciculatum, Gutierrezia sarothrae, Hymenoclea salsola, Bassia americana (= Kochia americana), Larrea tridentata, Malosma laurina, Myoporum laetum, Pluchea sericea, Prosopis glandulosa, Rhus integrifolia, and/or Suaeda taxifolia plus several others. The herbaceous layer, if present, is usually dominated by graminoids. There may be inclusions of Calamovilfa longifolia, Distichlis spicata (where water remains ponded the longest), Eleocharis palustris, Pascopyrum smithii, Poa pratensis, Puccinellia nuttalliana, or Sporobolus airoides herbaceous types (West 1983b, Knight 1994).
Dynamics: No Data Available
Environmental Description: Climate: Cold interior desert. Soil/substrate/hydrology: Sites are generally flat to gently sloping and moderately saline, but some sites do occur on rolling to hilly fans and slopes. Sites typically have saline soils, a shallow water table and flood intermittently, on margins of intermittently flooded desert playas, and usually remain dry for most growing seasons. The water table remains high enough to maintain vegetation, despite salt accumulations, often with fine soils such as clays (West 1983b, Knight 1994).
Geographic Range: This group occurs throughout much of the western U.S. in intermountain basins.
