Covering the Holocene alluvial floodplain deposits of the larger and wider streams or bayous, the Floodplains and Low Terraces ecoregion is distinct from the surrounding prairie uplands of Ecoregion 34a. The region in Louisiana has some similarities to the floodplain forests of Ecoregion 35b to the north. In most of Ecoregion 34c, however, the floodplains and low terraces have a different bottomland forest than the floodplains of Ecoregion 35. Bottomland forests of pecan, water oak, live oak, and elm are typical, with some bald cypress on larger streams. In Louisiana, the region includes the Mermentau River and its larger tributaries, as well as parts of Lacassine Bayou and tributary streams. Large portions of forest have been removed. Current land cover is a mix of wetland deciduous forest, upland mixed and deciduous forest, along with some cropland and pasture. Soils in the Louisiana portion are mostly very poorly and poorly drained Alfisols and Entisols with silt loam or very fine sandy loam surface textures.
