Name:
Schizachyrium scoparium - Paspalum plicatulum - Schizachyrium tenerum Grassland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance includes midgrass and tallgrass prairie vegetation occurring along the inner and outer Gulf Coastal Plain of Texas and Louisiana. Dominant or codominant grasses include <i>Schizachyrium scoparium var. scoparium, Paspalum plicatulum, Schizachyrium tenerum, Sorghastrum nutans</i>, and <i>Andropogon gerardii</i>, occurring with <i>Panicum virgatum, Paspalum floridanum, Sporobolus compositus, Setaria</i> spp., <i>Tridens strictus</i>, and <i>Muhlenbergia capillaris</i>. These prairies are typically species rich; co-occurring forbs may include <i>Helianthus mollis, Euthamia leptocephala, Symphyotrichum ericoides, Mimosa microphylla, Neptunia lutea</i>, Eryngium yuccifolium, and <i>Liatris</i> spp. Overgrazing and fire suppression of these grasslands have led to the invasion of a wide variety of woody species such as <i>Rosa bracteata, Vachellia farnesiana, Morella cerifera</i>, and <i>Triadica sebifera</i>. Some of these grasslands occur on upland acidic Vertisols and Alfisols of the Coastal Prairie in Louisiana and Texas and on acidic Alfisols of the more inland portion of the Fayette Prairie in Texas. These prairies are often characterized by the occurrence of low, circular mounds called mima or pimple mounds, which add local relief to an otherwise flat topography. When mima mounds are present, this alliance represents the drier vegetation of the mounds.
