The floodplains and terraces of the creeks and rivers would have supported irregular ribbons of woodlands and gallery forests, typically dominated by hackberry and cedar elm with components of pecan, sycamore and cypress, depending upon the specific characteristics of the soils and the terrain.
A thick woodland of post oak, live oak, and black hickory would have occurred on the old dune ridges to the south.
This unique convergence of diverse plant communities and topographic variability supported, and still supports, a wonderful diversity of wildlife. Black bear, antelope, and prairie chickens, now gone, were once common residents in the region.
