Common (Translated Scientific) Name: Foxtail Barley Great Plains Wet Meadow

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This foxtail barley community type is found in the northern and central Great Plains of the United States and Canada, ranging from South Dakota to Saskatchewan. Stands are found in lowlands with moderately to strongly saline or alkaline soils. The topography is flat, and the soils are often flooded or saturated in the spring. The vegetation is dominated by short and medium tall graminoids with a total vegetation cover of nearly 100%. Shrubs are usually absent. Hordeum jubatum dominates the community. Other common species in this community are Elymus trachycaulus, Distichlis spicata, Pascopyrum smithii, Poa arida, Poa compressa, and Rumex crispus.

Classification Comments: Although this is a common community type in the interior western United States, it is poorly sampled and defined. This abstract is based on two descriptions of Hordeum jubatum-dominated stands which are assumed to be examples of this community. These stands may be variants of ~Distichlis spicata - Hordeum jubatum - Puccinellia nuttalliana - Suaeda calceoliformis Wet Meadow (CEGL002273)$$ and ~Pascopyrum smithii - Hordeum jubatum Wet Meadow (CEGL001582)$$. Both communities usually contain Hordeum jubatum and Distichlis spicata or Pascopyrum smithii in varying amounts. The presence of Puccinellia nuttalliana or Suaeda calceoliformis may be distinguishing factors. They appear to be more characteristic of strongly saline areas, while Hordeum jubatum can dominate on less saline sites (Redmann 1972). Classification problems may arise on intermediate sites when Hordeum jubatum is the dominant species and Distichlis spicata, Pascopyrum smithii, Puccinellia nuttalliana, and Suaeda calceoliformis are present in more than minor amounts.

Floristics: The typically dense vegetation is dominated by short and medium-tall graminoids with a total vegetation cover of nearly 100%, but it may occur as sparser stands (15-30% cover) (Barnes and Tieszen 1978, Von Loh 2000). Shrubs are usually absent. Hordeum jubatum dominates the community. No other dominants are usually associated with this association, perhaps due to fluctuating moisture conditions in combination with an alkaline or saline environment. Other common species in this community are Elymus trachycaulus, Distichlis spicata, Pascopyrum smithii, Poa arida, Poa compressa, Rumex crispus, Ambrosia tomentosa, and Malvella leprosa. Introduced species may be common in some stands, including Bassia scoparia (= Kochia scoparia), Sonchus arvensis, and Lepidium latifolium.

Dynamics:  Total vegetation cover (density and height), species composition, and soil salinity depend on the amount and timing of precipitation and flooding. Growth-inhibiting salt concentrations are diluted when the soil is saturated, allowing the growth of less salt-tolerant species and more robust growth (Ungar 1967). Hordeum jubatum will replace Distichlis spicata in those communities when heavily grazed (Jones and Walford 1995).

Environmental Description:  This association has been reported from lowlands across the northern Great Plains. The climate is semi-arid continental with mean annual precipitation of 25-48 cm. Elevation generally ranges from 600-1600 m. Stands are located in lowlands with moderately to strongly saline soils (Barnes and Tieszen 1978). The topography is flat, and the soils are often flooded or saturated in the spring (Redmann 1972). Hordeum jubatum is often found dominating disturbed areas such as roadsides and overgrazed bottomland.

Geographic Range: This foxtail barley community type is found in the northern and central Great Plains of the United States and Canada, ranging from South Dakota to Saskatchewan.

Concept Lineage: The archived association (CEGL001798) was split into two new associations, with CEGL005286 (Great Plains) assigned to Group G324 and CEGL005285 (Great Basin) assigned to Group G538.decision needs further review, and the descriptive or distributional material for each will require review and editing.
