Since 1971, Save Mount Diablo has been committed to preserving land on and around Mount Diablo. December 7, 2021 marks our 50th anniversary, and we are celebrating all year round from December 7, 2021 to December 7, 2022.

50th Anniversary Oral History

We commissioned a very special oral history for our 50th anniversary with UC Berkeley’s Oral History Center of The Bancroft Library.

Because Save Mount Diablo’s many achievements over the past 50 years are the result of teamwork, the oral history includes interviews with a variety of people.

They include current leaders, long-serving Board and staff members, some of our longest-term and most significant supporters, and a few of our important public agency partners.

This 50th anniversary oral history will be completed later in the year, and we look forward to sharing the results with all Save Mount Diablo supporters who have made our land conservation work possible over the last 50 years.

Mangini Ranch to Open as a Free Educational Preserve

During this year of celebrating our 50th anniversary, we’re proud to be opening our first free educational preserve at Mangini Ranch. The preserve is on schedule to open at the end of March 2022.

Learn more about the initiative in this blog post.
