The mountain is a mélange of plants, vertebrates, and invertebrates that celebrate the incredible diversity that once existed within our state ̶ a diversity that is vanishing at an astonishing rate, but that is being fiercely protected by people who simply refuse to allow it to disappear on the mountain. This talk will show you some of the natural wonders of this State and County Park and federally- protected nature reserve and biological hotspot.

David Nelson is an orthopedic hand surgeon who has long been a student of nature. He took a CNPS tour of San Bruno Mountain led by Doug Allshouse in 2013 and was hooked by the beauty of the mountain and Doug’s talent for explaining nature. When he proposed doing a book on the mountain to Doug, he discovered that Doug was already working on one and welcomed his participation.
