Mount Diablo is well known for its commanding presence in the Bay Area landscape. Even more importantly, it is home to hundreds of native plants. More than 150 species are considered rare, threatened, or endangered, and 13 are endemic (found only in the Mount Diablo region).
In 1944, Dr. Mary Leolin Bowerman, botanist and co-founder of Save Mount Diablo, first described these unique plants in The Flowering Plants and Ferns of Mount Diablo (updated by Mary Bowerman and Barbara Ertter in 2002). Non-native species have been introduced in recent times and, unfortunately, some have become invasive.
