<P> The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern United States covering 54,400 square miles ( 141,000 km ) of East Texas , southern Arkansas , western Louisiana , and southeastern Oklahoma . These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak . Historically the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries . The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States . The United States Environmental Protection Agency ( EPA ) defines most of this ecoregion as the South Central Plains . </P>
