Figure 1. Mapped extent
Areas shown in blue indicate the maximum mapped extent of this ecological site. Other ecological sites likely occur within the highlighted areas. It is also possible for this ecological site to occur outside of highlighted areas if detailed soil survey has not been completed or recently updated.
MLRA notes
Major Land Resource Area (MLRA): 152B–Western Gulf Coast Flatwoods
Major Land Resource Area (MLRA) 152B, Western Gulf Coast Flatwoods, is in eastern Texas and western Louisiana. Locally termed the Flatwoods, the area is dominated by coniferous forest covering 5,681 square miles (14,714 square kilometers). The region is a hugely diverse transition zone between the northern and eastern mixed forests and southern and western coastal prairies and grasslands.

Ecological site concept
The Sandy Terrace ecological site has deep sandy soils greater than 80 inches (203 centimeters) with little horizon development. The upland landscape, coupled with properties associated with the depth of the sand, forms its unique plant community.
Associated sites

Acid Baygall Soils have a spodic horizon and are extremely acid. Sites are not open and have dense thickets of large gallberry. |
---|---|
F152BY010TX |
Terrace Soils have an increase in clay causing more water availability to plants. Sites have higher plant productivity potentials. |

Well Drained Loamy Upland Soils have an increase in clay, causing more water availability to plants. Sites have higher plant productivity potentials, typically with higher canopy covers, higher basal areas, and more robust herbaceous plant communities. |
