Sierra Forever has been committed to serving the Sierra Nevada and Great Basin region for over fifty years. As one of the oldest nonprofits in the region, Sierra Forever was established in 1970 by visionary citizens interested in helping the U.S. Forest Service provide interpretive education relevant to the unique surrounding landscape and to communicate with the public about the importance of public lands of the Sierra. Before receiving its 501(c)(3) nonprofit status in 1972, Sierra Forever became one of the first independent organizations in the United States to operate under a Participating Agreement with the U.S. Forest Service for interpretive services.

Sierra Forever is committed to providing high quality interpretive and educational programs, literature, products and events with the goal of creating strong emotional and intellectual connections between people and the public lands of the Eastern Sierra, motivating them to protect and preserve this region through effective stewardship, responsible behavior and personal investment.
