CEGL002247 Schizachyrium scoparium - Bouteloua curtipendula Chalkflat Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Little Bluestem - Sideoats Grama Chalkflat Grassland
Colloquial Name: Little Bluestem Chalkflat Mixedgrass Prairie
Hierarchy Level: Association
Type Concept: This little bluestem mixedgrass prairie community is limited to the south-central Great Plains in the United States. Stands occur on nearly level to gently sloping terraces below chalk or limestone outcrops. They are not flooded or saturated during the year. Soils are well-drained and moderately deep to deep. They are strongly calcareous with silty or loamy surface layers and subsoils. The parent material is chalky shale and soft limestone. The vegetation structure is typically a dense stand of short to medium-tall graminoids and forbs. Bouteloua curtipendula and Schizachyrium scoparium are the most abundant. Andropogon gerardii and Bouteloua dactyloides are also typically found in this community. Sporobolus cryptandrus, Distichlis spicata, Eriogonum effusum, Gutierrezia sarothrae, Oenothera macrocarpa, Stanleya pinnata, and Atriplex canescens are among many species characteristic of this community.
