Famed biologist E.O. Wilson once named San Bruno Mountain one of the world biodiversity hotspots, because so many native species remained here, isolated by the city below. A must-see!
A hulking presence on San Francisco’s southeastern border, San Bruno Mountain forms a natural boundary between San Francisco and the Peninsula. Though development has several times threatened to pave its slopes, the mountain has remained a unique island of open space in a sea of residential sprawl. This continued salvation is courtesy of a density of rare species–so many that biologist E.O. Wilson once named San Bruno Mountain one of eighteen global biodiversity hotspots in need of protection.
