Name: Sporobolus airoides - Sporobolus wrightii - Panicum obtusum Lowland Desert Grassland Alliance
Reference: NatureServe Biotics 2019
Description: This lowland grassland alliance is characterized by a moderately dense to dense graminoid layer of perennial grasses dominated by <i>Sporobolus wrightii, Sporobolus airoides</i>, or <i>Panicum obtusum</i>. Scattered shrub or succulent species may be present, especially on degraded sites and along drainages and in depressions. Other mesic graminoids such as <i>Panicum hallii, Pascopyrum smithii</i>, or <i>Schizachyrium scoparium</i> may be present to codominant. This alliance is found in the northern Chihuahuan Desert and adjacent Sky Islands and Sonoran Desert, extending into the southern Great Plains. Stands occur on alluvial flats, loamy plains, and basins sometimes extending up into lower piedmont slopes and on broad mesas. Included in this alliance are mesic grasslands that occur in relatively small depressions or swales and along drainages that receive runoff from adjacent areas. Occupying low topographic positions, these sites generally have deep, fine-textured soils that are neutral to slightly or moderately saline/alkaline.
