The Floodplains and Low Terraces ecoregion contains floodplain and low terrace deposits downstream from Ecoregion 32 and upstream from Ecoregions 34 and 35. It includes only the wider floodplains of major streams, such as the Sulphur, Trinity, Brazos, and Colorado rivers. In addition, it covers primarily Holocene deposits and not Pleistocene deposits on older, high terraces. The bottomland forests contain water oak, post oak, elms, green ash, pecan, willow oak to the east, and to the west some hackberry and eastern cottonwoods. The northern floodplains tend to have more forested land cover, while in the south the Brazos and Colorado River floodplains are characterized by more cropland and pasture.
