Susan volunteer profileSave Mount Diablo works to preserve land in two ways: acquisition including land purchases by our organization or our allies, and as a condition of land use planning.

Save Mount Diablo has developed and pursued a systematic approach to land acquisition.  Our goal is to expand existing preserved lands and connect them with wildlife and recreational corridors.   One of our highest acquisition priority areas includes the wildlife corridors surrounding and including the Marsh Creek-Morgan Territory region, a 60-mile circle of open space east of Diablo's peaks. 

Park agencies most commonly seek to protect parcels adjacent to park boundaries.  Save Mount Diablo has often acquired non-adjacent lands, leading to protection and new parks. Save Mount Diablo can often work faster than agencies to acquire strategic parcels and then hold them until agencies are ready to manage them.  We work closely with the park agencies in the area on natural resource issues and long range planning for the entire Mount Diablo region.

Save Mount Diablo completes several acquisition projects each year, and works with our agency allies on others. Some projects span years. Due to the State’s economic situation, state park land acquisitions are currently stalled. At the same time, the downturn in the economy has resulted in more properties being on the market at lower prices. Save Mount Diablo continues to evaluate and pursue acquisition projects for future addition to Mount Diablo State Park.

For example, in 1994 Save Mount Diablo’s 333-acre Chaparral Spring acquisition was the first step in the creation of a corridor between Mount Diablo State Park and Black Diamond Mines Regional Preserve.  By 2005, three neighboring properties had been acquired by East Bay Regional Park District with Save Mount Diablo’s help, leaving just a quarter mile gap between the two parks.  In 2008 we transferred the Chaparral Spring property to the EBRPD with the help of a grant from the Coastal Conservancy.

Save Mount Diablo's properties are closed to the public except by guided tour. Please see our Hike Calendar for upcoming dates and opportunities.

Chaparral SpringChaparral Spring – A Key in the Mount Diablo to Black Diamond Mines Corridor
Save Mount Diablo made its first step north of Marsh Creek Road with the purchase of 333-acre Chaparral Spring in 1994. Fifteen years later, with a grant from the Coastal Conservancy, we have transferred the property to East Bay Regional Park District for long term management. Adjacent to the Park District’s 1,030-acre Clayton Ranch (a joint project with Save Mount Diablo), Chaparral Spring was the most critical parcel in creating a corridor of protected lands from Mount Diablo State Park to Black Diamond Mines Regional Preserve which was completed in 2011.
