Parent Description

Central Mixedgrass Prairie represents the common prairie type in the Rolling Plains. This prairie often has Schizachyrium scoparium (little bluestem) as a dominant, with Nassella leucotricha (Texas wintergrass), Bouteloua curtipendula (sideoats grama), Bothriochloa laguroides ssp. torreyana (silver bluestem), Bouteloua hirsuta (hariy grama), Bouteloua gracilis (blue grama), Bouteloua dactyloides (buffalograss), Andropogon gerardii (big bluestem), Pascopyrum smithii (western wheatgrass), Aristida purpurea (purple threeawn), Sporobolus cryptandrus (sand dropseed), and Pleuraphis mutica (tobosa) also commonly encountered. Grazing tends to favor shortgrass species such as Bouteloua dactyloides (buffalograss) and Bouteloua gracilis (blue grama). Sandy soils may be similar, but typically have greater cover of Sporobolus cryptandrus (sand dropseed) and forbs such as Eriogonum annuum (annual wildbuckwheat), Heterotheca canescens (gray goldaster), Dimorphocarpa candicans (Palmer’s spectaclepod), and Gaillardia pulchella (Indian blanket). This system is frequently invaded by juniper (primarily Juniperus pinchotii (redberry juniper)), Ziziphus obtusifolia (lotebush), and Prosopis glandulosa (mesquite), and sandier sites may contain some Artemisia filifolia (sand sage) and Quercus havardii (Havard’s shin oak).
