Flora and fauna
The area contains badlands with mesquite, cacti and junipers with tall grasses, plums, hackberries and cottonwoods in the canyons.
The park hosts the Texas state bison herd. At the urging of his wife, Charles Goodnight preserved several plains bison from those that were being slaughtered. This herd became one of the genetic sources from which current bison herds descend. The state herd only contains plains bison which have no cattle DNA.
African aoudad sheep (barbary sheep), mule deer, white-tailed deer, coyotes, opossums, raccoons, bobcats, foxes, porcupines, numerous species of snakes and lizards, and over 175 species of birds including Golden Eagles are found within the park. Lake Theo contains bass and catfish.
Average minimum temperature in January is 19 °F (−7 °C). The average maximum in July is 91 °F (33 °C). Average rainfall is 20.4 in (520 mm).
