Pasture/Prairie brome, and tall fescue. Areas with lower levels of grazing may have species such as
little bluestem, yellow Indiangrass, and big bluestem among the dominants.

This type is mapped in broken landscapes associated with weathering of sedimentary
rocks that do not contain much gyp. Common shrubs include skunkbush sumac,
fragrant sumac, Mohr shin oak, Chickasaw plum, lotebush, and mesquite (within range).
