also grew in semishade [ILLUSTRATION FOR FIGURE 3 OMITTED].
Major prairie grasses such as Andropogon gerardii
and Sorghastrum nutans reproduce vegetatively (McKendrick et al.
Tallgrass prairie is the predominant vegetation of the TPP, and the dominant grass species include Andropogon gerardii
, Sorghastrum nutans, Sporobolus compositus, Panicum virgatum, and Schizachyrium scoparium (Palmer, 2007).

In Mississippi, Hill and Seltzer (2007) recently added Andropogon gerardii
and Tripsacum dactyloides to the list for a relatively well known site--the Osborn Prairie of Oktibbeha County.
Usually each of the nine fields was planted to Sorghastrum nutans and either Andropogon gerardii
or Schizachyrium scoparium as a second native grass species (Simpson & Esker 1997).

The most abundant graminoids were Schizachyrium scoparius (little bluestem), Andropogon gerardii
(big bluestem), Panicum lanuginosum (panic grass), and Carex pensylvanica.
