We are on a time-sensitive land conservation mission.

Save Mount Diablo is working to preserve, defend, and restore the remaining 60,000 acres on and around Mount Diablo and its foothills for wildlife and people to enjoy.

Our Mission

My dream is that the whole of Mount Diablo, including its foothills, will remain open space…
that the visual and natural integrity will be sustained.

Many Acres of Wild Lands Have Been Saved


In 1971, there was just one park on Mount Diablo. It consisted of only 6,788 protected acres, mostly around the peak.

Working with partners such as California State Parks and Contra Costa County, the East Bay Regional Parks District, local cities, the Coastal Conservancy, Contra Costa Water District, and others–we, together with the help of generous supporters like you, have pieced together a conserved expanse of Diablo Wild lands that today is greater than 110,000 acres, an area bigger than Point Reyes National Seashore or the Golden Gate National Recreation Area.

Although we and our partners have had tremendous success at reassembling a large swath of the wild lands around Mount Diablo, there is still much work to do to save the remaining unprotected lands and allow our community to grow.

Protected Lands

More Wild Land is at Risk.

Over 60,000 acres of natural lands are still threatened by development.

With 2 million more people predicted to move into the Bay Area by 2045 and the current red-hot real estate market, our window for saving this land is closing fast. Once our precious green and gold mosaic is lost, it will be lost forever.

What’s At Stake?

FOREVER WILD: The Campaign to Save Diablo’s Wild Lands

Leave a legacy that will pay lasting green and gold returns… forever.

The FOREVER WILD Capital Campaign will create land acquisition, stewardship and defense funds to protect our beloved Mount Diablo and its neighboring open spaces in perpetuity.

Since losing critical natural resources to development is a permanent loss, we need to be ready to act immediately when sensitive land becomes available. Thus, we are looking for investors to empower us to be ready to buy and then oversee and steward these investments for generations to come.

Your gift will make a lasting impact on regional land protection for the benefit of future generations and wildlife, in perpetuity. Please consider supporting Save Mount Diablo’s mission with a generous gift to the Forever Wild Campaign. 

Note: Gifts of stock, property, and irrevocable bequests, as well as outright cash gifts, are acceptable. We can also accept multi-year pledges.

For questions about arranging your special gift, please contact Marcia Slackman, Development Director at or call her at (925) 949-4513.  THANK YOU!!

Contributions to Save Mount Diablo’s FOREVER WILD Capital Campaign should be considered special, long-term investments in Save Mount Diablo beyond normal annual gifts, which are also critical, to support our regular annual operations.
