CEGL002397 Schizachyrium scoparium - Sorghastrum nutans - Aristida lanosa - Polypremum procumbens Sand Grassland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Little Bluestem - Indiangrass - Woolly-sheath Three-awn - Juniper-leaf Sand Grassland

Colloquial Name: Mississippi Embayment Sand Prairie

Hierarchy Level:  Association

Type Concept: This little bluestem sand prairie is found in the United States in the Mississippi Embayment of Missouri and sand barrens in southwestern Indiana. Stands occur on nearly level to steeply sloped elevated terraces, knolls, ridges, and natural levees. The parent material is eolian or alluvial sand, associated with the Bulltown Soil Series. This tallgrass or midgrass prairie is composed of a single layer of dominant graminoids intermixed with abundant forbs. The herbaceous layer is dominated by Schizachyrium scoparium and Sorghastrum nutans. Other species can include Lithospermum canescens, Cyperus spp. (including Cyperus grayoides), Polypremum procumbens, Desmodium strictum, Digitaria cognata, Aristida spp., and Callirhoe triangulata.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The type concept is taken largely from the Missouri state types dry sand prairie and dry-mesic sand prairie, at least for the southeastern Missouri part (Nelson 1985). The two state types may each need their own global type. Stands in northern Missouri along the Mississippi River are tracked with ~Schizachyrium scoparium - Danthonia spicata - Carex pensylvanica - (Viola pedata) Sand Grassland (CEGL002318)$$. This community is often near sand savanna communities. Type has been extirpated from Arkansas. Name needs revision in Missouri. Stands in Indiana occur in Vigo, Sullivan and Tippecanoe counties and may be a separate type.

Physiognomy and Structure: No Data Available

Floristics: This community is composed of a single layer of dominant graminoids intermixed with abundant forbs. This sand prairie can be a tallgrass or a midgrass prairie. It is dominated by Schizachyrium scoparium and Sorghastrum nutans. Other species can include Lithospermum sp., Cyperus spp. (including Cyperus grayoides), Polypremum procumbens, Desmodium strictum, Digitaria cognata (= var. cognata), Aristida spp., and Callirhoe triangulata (Nelson 1985).

Dynamics:  Stands are maintained by fire with an average burn frequency of 1-5 years on the mesic sites and 5 years on the dry-mesic sites (Nelson 1985).

Environmental Description:  Both the drier and more moist portions of this community are subject to drought stress (Nelson 1985).

Geographic Range: This bluestem sand prairie is found in the United States in the Mississippi Embayment of Missouri and sand barrens in southwestern Indiana, and at least historically in Arkansas and possibly Illinois.
