In the 1960s, local resident and conservationist Terry Hershey, working with local congressman (and eventual President) George H.W. Bush, prevented the federal government from lining the straightened sections of the bayou with concrete. In 1966, Hershey and a number of other homeowners in the Memorial area formed the Buffalo Bayou Preservation Association, which later expanded its mission and became the Bayou Preservation Association. In 1989, Terry Hershey Park, which runs parallel to the bayou between Beltway 8 and Highway 6, was dedicated to her efforts. The bayou is one of the only bayous in Houston to retain its natural riparian ecosystem.
