San Bruno Mountain Watch

The members of San Bruno Mountain Watch have been working diligently for over thirty years to help protect and preserve San Bruno Mountain as the largest and richest remaining example of the native Franciscan bioregion, elsewhere destroyed by the spread of San Francisco and its neighboring cities in the urbanized northern San Francisco Peninsula. Close to one of the Bay Area's main airports and surrounded by five large suburbs and towns, the mountain shelters a remarkable number of rare and endangered species, including three butterflies and at least 15 plants, as well as other wild animals rarely found so close to cities. The mountain has been described as a natural classroom, "maybe the best place in the United States for the average person to find and observe an endangered plant or animal in the wild.² The International Union for the Conservation of Nature has described it as an "ideal site for biology classes and research" and a "prime location for continued ecological and evolutionary investigations."
