Name: Sporobolus airoides Great Plains Marsh Alliance
Reference: NatureServe Biotics 2019
Description: <i>Sporobolus airoides</i> is the dominant or codominant grass. Typical codominant grasses include <i>Muhlenbergia porteri, Panicum obtusum</i>, or <i>Scleropogon brevifolius</i>. Other common grasses are <i>Bouteloua dactyloides, Hordeum pusillum, Pascopyrum smithii</i>, and <i>Sporobolus cryptandrus</i>. Forbs and shrubs are typically sparse. Common forb associates are <i>Chaetopappa ericoides</i> and species of <i>Sphaeralcea, Machaeranthera, Ratibida, Helianthus</i>, and other Asteraceae spp. Scattered shrubs may include <i>Allenrolfea occidentalis, Atriplex canescens, Chrysothamnus</i> spp., <i>Gutierrezia sarothrae</i>, and <i>Sarcobatus vermiculatus</i>. This grassland alliance occurs in the western and southern Great Plains. Stands occur in a wide variety of lowland sites, such as stream terraces, swales, interdune basins, and alluvial flats. The soil often has a high water table because of land position and impermeable subsurface horizons. Soils are moderately saline and usually alkaline. Soil surface textures are sandy to clayey. The soils morphology often includes a claypan, caliche layer or other subsurface horizon that impedes water movement. Parent material is typically alluvium derived from limestone, shale, or sandstone.
