There are many natural wonders and places of historic interest in California that are worth preserving.
And so there is a public aspect of it through the state government of California. Put there is also the part that citizens play in banding together to advocate for and do projects for the benefit of parks.
Thus, I'm supporting California State Parks Foundation.
Here is their "about us" paragraph:
The California State Parks Foundation (CSPF) was founded in 1969 by William Penn Mott, Jr., former director of both California's Department of Parks and Recreation and the National Park Service. With our 120,000 members, CSPF is the only statewide independent nonprofit organization dedicated to protecting, enhancing and advocating for California's magnificent state parks. Since 1969, CSPF has raised more than $170 million to benefit state parks. CSPF is committed to improving the quality of life for all Californians by expanding access to the natural beauty, rich culture and history, and recreational and educational opportunities offered by California's 278 state parks—the largest state park system in the United States.
