CEGL005280 Schizachyrium scoparium - Sorghastrum nutans - Tradescantia bracteata Alkaline Bedrock Grassland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Little Bluestem - Indiangrass - Sticky Spiderwort Alkaline Bedrock Grassland

Colloquial Name: Midwest Dry-Mesic Limestone - Dolomite Prairie

Hierarchy Level:  Association

Type Concept: This dry-mesic alkaline grassland community is found in the central midwestern United States, in Missouri. Stands occur on gentle to moderately steep slopes of rolling hills and plains. The soil is typically well-drained, shallow to moderately deep (40-100 cm), neutral to slightly alkaline, stony, and formed over dolomite or limestone. Bedrock outcrops may be present. The vegetation in this community is typically medium dense and dominated by a combination of mid and tall grasses. Schizachyrium scoparium, Sorghastrum nutans, and Andropogon gerardii are common dominants. Other frequently occurring herbaceous species include Baptisia australis, Carex meadii, Camassia scilloides, Dodecatheon meadia, Echinacea pallida, Nothocalais cuspidata, Nemastylis geminiflora, Psoralidium tenuiflorum, and Tradescantia bracteata. Woody species, such as Juniperus virginiana, are sometimes found, especially where fire has not occurred for long periods.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The concept of this type is based on Missouri''s dry-mesic limestone/dolomite prairie (Nelson 1985). Dry limestone/dolomite prairie is also tracked here, but in future revisions to the Missouri state classification, that type will be merged with either limestone glade or dolomite glade types (M. Leahy pers. comm. 1999).

Floristics: The vegetation in this community is typically medium dense and dominated by a combination of mid- and tallgrasses. Schizachyrium scoparium, Sorghastrum nutans, and Andropogon gerardii are common dominants. Other frequently occurring herbaceous species include Baptisia australis, Carex meadii, Camassia scilloides, Dodecatheon meadia, Echinacea pallida, Nothocalais cuspidata (= Agoseris cuspidata), Nemastylis geminiflora, Psoralidium tenuiflorum (= Psoralea tenuiflora), and Tradescantia bracteata. Woody species, such as Juniperus virginiana, are sometimes found, especially where fire has not occurred for long periods (Nelson 1985).
