The southeast is in the Post Oak Savannah vegetation area, characterized by tall grasses and post and blackjack oaks. Between 21 and 30 percent of the land is considered prime farmland. Natural resources include oil and natural gas. Among the animals commonly found in the county are white-tail deer, bobcats, coyotes, opossums, squirrels, foxes, armadillos, skunks, bats, cottontail rabbits, raccoons, and numerous reptile, fish, and bird species.
