CEGL002250 Bouteloua curtipendula - Bouteloua (eriopoda, gracilis) Grassland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Sideoats Grama - (Black Grama, Blue Grama) Grassland

Colloquial Name: Grama Mixedgrass Prairie

Hierarchy Level:  Association

Type Concept: This grassland association is found in Texas and may also occur in Oklahoma, New Mexico and northern MexicoAdditional global information will be added as it becomes available. The composition and structure of this community are influenced by climate, soil (texture and depth), topography, natural fire, and grazing pressure. It occurs on moderately deep, upland soils that are usually calcareous and of a loamy texture. Terrain is usually moderately sloping to rolling but may be steep in some cases. Infiltration is moderately rapid to moderately slow and runoff is moderate. This community occurs on uplands dominated by herbaceous species, mainly mid and short grasses. Bouteloua curtipendula is usually the dominant species, with lesser amounts of Bouteloua gracilis, Bouteloua eriopoda, Bouteloua hirsuta, Sporobolus cryptandrus, and Aristida purpurea. Forbs make up less than 10% of the community with the major species being Sphaeralcea coccinea, Chaetopappa ericoides, Liatris punctata, Krameria lanceolata, Zinnia grandiflora, Tetraneuris scaposa, Gutierrezia sarothrae, and Ambrosia psilostachya. There are a few short shrubs present, mainly Mimosa aculeaticarpa var. biuncifera, Yucca glauca, Prosopis glandulosa, and Rhus trilobata. Occasional Opuntia macrorhiza also occurs.
