The Friends assist the city and county rangers through such activities as leading interpretive walks, performing wildlife and other scientific studies, removing invasive exotics and replanting with natives, installing kiosks, and coordinating Scout projects. Past scout projects have included building small bridges, installing interpretive signs, building and installing owl boxes, and restoring trails.
