CEGL001582 Pascopyrum smithii - Hordeum jubatum Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Wheatgrass - Foxtail Barley Wet Meadow
Colloquial Name: Western Wheatgrass - Foxtail Barley Saline Prairie
Hierarchy Level: Association
Type Concept: This wheatgrass saline prairie type is found in the northern Great Plains of the United States and adjacent Canada. Stands occur in temporarily flooded sites (playas and stock ponds) with deep, poorly drained, clayey, alkaline-saline soils. Stands occur as small patches in temporarily flooded sites, surrounded by grasslands or shrublands. Grasses dominate the vegetation. Pascopyrum smithii (or Elymus lanceolatus) and Hordeum jubatum are the major species, and other species from the surrounding matrix vegetation may be present.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Stands apparently occupy soils with higher sodium concentrations than do stands of the similar ~Pascopyrum smithii - Eleocharis spp. Wet Meadow (CEGL001581)$$ (Bergman and Marcus 1976), or playas where the surface dries and the water table drops more quickly (BLM 1979b). This association has not been described well. Further analysis of existing information and additional inventory will be helpful in determining the range of variation in stands of this type and how this type differs from other vegetation types of temporarily flooded sites.

Physiognomy and Structure: No Data Available
Floristics: Grasses contribute most of the cover in this association, although forbs and scattered shrubs may be present. Pascopyrum smithii or Elymus lanceolatus dominate, and Hordeum jubatum contributes substantial cover. Other species may be present but contribute little cover. Stands in south-central Wyoming contain scattered Atriplex gardneri from the surrounding vegetation (Medicine Bow Mine Application n.d.).
Dynamics: No Data Available
Environmental Description: Stands of this association occupy temporarily flooded sites (playas and stock ponds) with deep, poorly drained, clayey, alkaline-saline soils. This type occurs on drawdown zones around reservoirs in eastern Montana (S. Cooper, MTNHP, pers. comm. 1998).
Geographic Range: This wheatgrass saline prairie type is found in the northern Great Plains of the United States and adjacent Canada, extending from Montana to Nebraska, and north to Alberta and possibly Saskatchewan.
