SAVE MOUNT DIABLO!
It is the rallying cry that inspired our founding in 1971 and it’s still the reason we exist today.
How We Preserve Diablo’s Wildlands
Save Mount Diablo preserves, defends and restores the natural lands on Mount Diablo and its foothills for wildlife and people to enjoy.
- We preserve property through perpetual conservation easements and acquisition;
- We care for and restore the lands we buy through stewardship prior to turning them over to a park system, protected for wildlife and future generations;
- We defend our area of interest through advocacy and land use planning to ensure that habitats and wildlands are protected when development takes place;
- We educate the public about the Diablo area’s special wildlife and cultural history;
- We host numerous events and activities on the mountain to encourage recreation consistent with the protection of natural resources;
More Lands are at High Risk
Contrary to what many think, Mount Diablo is not saved, its lands not fully protected, and there is still much more we need to do to save these wildlands in our own backyard.
- While nearly two-thirds of the mountain is protected as parks, watershed lands, and preserves, about 70,000 acres are still at risk for development north of Highway 580.
- Maintaining necessary wildlife corridors in the Diablo Range south of Highway 580 and Altamont Pass affect even more lands.
Once the land is lost, it is gone forever.
What’s at Stake?
Imagine a Mount Diablo that was once 180,000 acres of wildlands: more than 280 square miles of canyons, cliffs, woodlands, meadows, streams, microclimates and unique habitats sheltering 900 species of plants and animals, 14 only found on the mountain, dozens rare or endangered.
Over time, these wild lands have been carved into pieces, creating a checkerboard of developed and natural lands, some publicly and some privately owned. These fragmented lands hinder wildlife survival, increase pollutants in our creeks and streams, and severely limit public access.
With community help, Save Mount Diablo can stem the rapidly accelerating pace of development and sprawl that threaten the last remaining open lands at risk, land that could be developed over the next ten years. We can preserve unprotected land through strategic land acquisitions and stewardship that will counter the threat of habitat loss, restore connections between existing natural areas, and provide the possibility of new trails and recreation areas.
Protecting the remaining Diablo wildlands is an extraordinary undertaking. It’s our mission to continue the legacy of conservation started by generations of residents of the Mount Diablo area who had a fierce love of the mountain. Now, together, we must further protect and restore one of the most important natural areas in California.
Together in Partnership
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 wildlands that today is greater than 110,000 acres, an area bigger than Point Reyes National Seashore or the Golden Gate National Recreation Area.
Save Mount Diablo facilitates a number of programs intended to educate the public about the priceless value of preserving Diablo’s immensely rich biodiversity and majestic landscape, and works to keep you informed about the important land conservation issues affecting the East Bay area, such as climate change and development projects that threaten to destroy important habitat and deteriorate the quality of life in our community.

Map of Protected Lands from 1971 to 2016
Since Save Mount Diablo’s founding in 1971, the preserved lands on Mount Diablo and its foothills have been increased from just over 6,788 acres in one park to over 110,000 acres and more than 40 parks.
Area of Interest
Although we and our partners have had tremendous success at reassembling a large swath of the wildlands around Mount Diablo, there is still much work to do to save the remaining unprotected lands and allow our community to grow.
Save Mount Diablo’s area of interest is from I-680 to the west, I-580 to the south, Suisun Bay to the north and Delta to the east. Save Mount Diablo’s Area of Interest includes the East Bay’s undeveloped hilly lands, watersheds and valleys east of Hwy 680 to the Byron Highway, and south across Highway 580 and Altamont Pass, areas which can still be connected to the more than 40 existing Diablo parks and preserves, or new preserves as they are developed. The organization’s acquisition, land use, and policy priorities can be described as concentric rings around those parks and preserves.
The area of interest falls into one of eight distinct geographic areas of interest with eight sub-areas, as listed below along with projects. To maximize preserved land, Save Mount Diablo has developed unique preservation strategies for each of these.
