Name: Pleuraphis mutica Lowland Desert Grassland Alliance
Reference: NatureServe Biotics 2019
Description: Vegetation is characterized by a moderately dense to dense graminoid layer of perennial grasses that is typically dominated by <i>Pleuraphis mutica</i>. Dense stands of <i>Pleuraphis mutica</i> can occur in mesic swales and depressions and along drainages (tobosa swales), sometimes with other mesic graminoids such as <i>Panicum obtusum, Pascopyrum smithii</i>, or <i>Schizachyrium scoparium var. scoparium</i>. <i>Sporobolus airoides</i> may be present in alkaline soils, but does not codominate. In degraded stands, <i>Scleropogon brevifolius</i> or <i>Aristida</i> spp. may codominate. <i>Bouteloua gracilis</i> may become important in northern stands transitioning into the Great Plains and on degraded desert stands. Scattered shrub or succulent species may be present, especially on degraded sites and along drainages and in depressions. This lowland grassland alliance occurs in the northern Chihuahuan Desert and adjacent Sky Islands and Sonoran Desert, extending into limited areas of the southwestern 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.
