Name: Pascopyrum smithii - Panicum obtusum - Bouteloua dactyloides Playa & Rainwater Basin Wetland Group
Reference: NatureServe Biotics 2019
Description: Communities within this group are associated with the playa lakes and rainwater basins in the central Great Plains south to New Mexico and the Edwards Plateau in Texas. Perennial grasses &lt;1 m tall dominate most examples of this group, sometimes forming dense sod cover. Where the duration of flooding is longer and kills or inhibits the perennial grasses, annuals can be common when the ground dries. Typical perennial grasses are <i>Bouteloua dactyloides, Panicum obtusum, Panicum virgatum</i>, and <i>Pascopyrum smithii</i> while annuals may include <i>Cyperus</i> spp., <i>Echinochloa</i> spp., and <i>Polygonum</i> spp. Dominant species typifying examples in the Edwards Plateau may include <i>Bouteloua dactyloides, Chaetopappa bellidifolia, Paronychia</i> spp., <i>Pleuraphis mutica, Sedum nuttallianum, Sedum pulchellum, Sporobolus vaginiflorus</i>, and the alga <i>Nostoc commune</i>. The group is primarily found in upland depressional basins. Sites are typified by the presence of an impermeable layer, such as a dense clay, hydric soil, and is usually recharged by rainwater and nearby runoff. They are rarely linked to outside groundwater sources and do not have an extensive watershed.
