In September 2011, 80 descendants of the great southern plains bison herd were released to roam 700 acres of grasslands in the park. From a safe distance, visitors can view these indigenous animals in their native habitat.

History was made on Aug. 19, 2014 at Caprock Canyons State Park as cow #120 took the first steps to lead the Texas State Bison Herd into their new range within the park. The herd now has over 10,000 acres to roam. This legendary bison herd was started by famed cattleman Charles Goodnight and his wife Mary Ann in 1878. It is one of the five foundation herds credited with saving this magnificent animal from extinction.
