Preserving land for people and wildlife.

Only half of Mount Diablo’s wild lands are preserved. The other half is at risk of being lost to development forever. We work to preserve, defend and restore the remaining natural lands for people and wildlife to enjoy.

Since Save Mount Diablo's founding in 1971, preserved open space has increased from less than 7,000 acres to over 110,000 acres in more than 40 parks. Mount Diablo is still threatened by development. That could mean the loss of wildlife corridors, ecosystems and recreational opportunities. Your support will preserve these natural lands forever to safeguard our quality of life, including the quality of our air, water and views.
