Typical perennial grasses include broomsedges (Andropogon virginicus
and its allies) and locally Muhlenbergia capillaris.
and Heterotheca subaxillaris and the grasses Andropogon virginicus
Three variables discriminated between the microhabitat surrounding traps that captured cotton rats and traps that captured white-footed mice: number of stems of black berries (Rubus spp.), number of clumps of broomsedge (Andropogon virginicus
) and shrub thickness.
The study was established as a complete 4 x 4 x 3 factorial arrangement of Pinus taeda, Liquidambar styraciflua, and Andropogon virginicus
. Pinus and Liquidambar were each planted at densities of 0, 1, 2, and 4 plants/[m.sup.2], and Andropogon at a density of 0, 4, and 16 plants/[m.sup.2], for a total of 48 treatments.

Some invasive plants included yaupon (Ilex vomitoria), broomsedge bluestem (Andropogon virginicus
), bullnettle (Cnidoscolus texanus), and red lovegrass (Eragrostis oxylepis).
In contrast, xeric grasses such as Aristida purpurascens (arrow feather) and Panicum capillare (old witch grass), and weedy species such as Poa compressa (Canada bluegrass), Andropogon virginicus
(broom-sedge), and Setaria glauca (yellow foxtail grass) increased.
Warm-season bunchgrasses native to Tennessee include big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), broomsedge bluestem (Andropogon virginicus
), indiangrass (Sorghastrum nutans), switchgrass, (Panicum virgatum), and eastern gamagrass (Tripsacum dactyloides).
Limesink wetlands in the region include: (1) marshes with coarse sandy soils, an open overstory and an understory of dense panic grasses (Panicum spp.) and cutgrass (Leersia hexandra); (2) cypress savannas with fine sandy soil underlain by a layer of clay, with a relatively open pond cypress (Taxodium ascendens) canopy and an understory of panic grasses and broomsedge (Andropogon virginicus
); and (3) cypress/gum swamps with thick organic soils and a dense overstory of pond cypress and swamp tupelo (Nyssa biflora) with virtually no understory or midstory vegetation (Kirkman et al., 2000; Battle and Golladay, 2001).
All four sites contained open (20 to 40%) canopies of longleaf pine with well-developed groundcover vegetation dominated by Andropogon virginicus
