San Francisco hosts two of the rarest manzanitas in the world: Raven's Manzanita (Arctostaphylos montana subsp. ravenii) and Franciscan Manzanita (Arctostaphylos franciscana). These endangered species grew together in a distinct maritime chaparral habitat that once covered the serpentine hilltops of San Francisco. Their story is one of loss, salvage, rediscovery, and serendipity. Michael Chassé will share the story of how San Francisco's rare endemic manzanitas were once thought to be lost forever, only to be rediscovered and brought back from the brink of extinction. Current efforts by park staff are restoring populations of these species to the San Francisco landscape.

Michael Chassé works for the National Park Service at the Golden Gate National Recreation Area, where he has coordinated natural areas stewardship and rare plant monitoring for close to 20 years. He is a graduate of the Department of Geography & Environment at San Francisco State University. His master's thesis focused on San Francisco's rare endemic manzanitas.
