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 Terrace ecological site has very deep soils on terrace landforms. These sites are located on a higher landform than bottomlands and are not as wet. The sites are situated on a lower landform than the uplands and are not as dry. The sites do not flood or pond, but instead have a water table from December to April. This unique position between the drier uplands and wetter bottomlands creates their plant community.
