F. The Thornthwaite P-E index is 56 to 68. These include the competing Lake Charles and Vamont series and the Dacosta , Edna , and Verland series. Dacosta, Edna, and Verland soils have loamy surface layers. All of these soils are on slightly higher landscape positions. Mainly used for growing rice and pasture.
Native grasses are mainly species of andropogon, paspalum, and panicum.
Various species of trees have encroached in a few areas. The series is of moderate extent. Bacliff soils were formerly included with the Beaumont series. Further study and characterization data of the series is needed to verify hydrology and classification. Soil Taxonomy, Second Edition,1999.
