The Post Oak Savannah is an ecological region in central/eastern Texas, shaped largely by fire and grazing. Historically, it was covered with lush grasses, herbaceous plants and few trees, and represented a transition between the great plains grasslands and the more forested ecosystems of the eastern US.
Post oaks and other trees were scattered amongst a backdrop of dense native grasses like little bluestem, providing healthy habitat for animals like deer, bison, quail, turkey, and Houston toads.
