San Bruno Mountain, located in the center of the San Francisco Bay Area, is a four-square-mile global treasure—a natural preserve touted by biologist E. O. Wilson as one of the world’s rare biodiversity hot spots. Bathed in fog and wind and preserved from destruction by the fierce work of local conservationists, San Bruno Mountain offers visitors a glimpse of what San Francisco looked like before colonization.
Drawing on years of visits, observations, and research, conservationists David L. Nelson and Doug Allshouse will help us understand this unique and precious place from the point of view of its plants. Through their beautiful photographs and engaging stories of the mountain and their adventures in exploring and documenting its diversity, they will take us on a virtual tour of this treasure across the Bay.
Doug and David are the authors of San Bruno Mountain: A Guide to the Flora and Fauna, published by Heyday in November 2022. This one-of-a-kind field guide offers a comprehensive flora of San Bruno Mountain and its endangered species, detailing a total of 528 plant species (among them 316 natives), along with the history of this living, changing habitat at the southern edge of San Francisco. The birds, butterflies, reptiles, geology, climate, dynamic changes, and political history of the preserve also feature in the book. You can purchase a copy of this comprehensive field guide through the state CNPS website.
David L. Nelson worked in the field of outdoor recreation before becoming a hand surgeon. He has also written three books for the Federation of Fly Fishers. He serves as chair for the Locally Rare Plant Committee of the Yerba Buena chapter of the California Native Plant Society.
Doug Allshouse was a founding member of Friends of San Bruno Mountain in 1995. He led his first field trip on the mountain in 1996 and continues leading trips for the Yerba Buena chapter of the California Native Plant Society today, where he serves as chair for the San Bruno Mountain Committee.
