Established in 1972, the Oklahoma Chapter of the Sierra Club is the largest environmental group in Oklahoma, fighting to protect our great outdoors. With more than 40 years of effort under our belt, and three Groups representing more than 3,000 members across our state, Sierra Club's Oklahoma Chapter looks forward to growing our presence and increasing our work in Oklahoma.
