Endangered Species in the Presidio

“California, and the Bay Area specifically, are places of great biological diversity owing to the wide variety of environmental conditions found here. On the San Francisco Peninsula, conditions leading to high biological diversity and species with limited distributions (endemic species) include 1) the interaction of maritime weather and Mediterranean climate to produce localized climatic zones, 2) the development of diverse habitats and barriers to dispersal by mountains and bay, and 3) the presence of a variety of geologic and soil conditions, such as nutrient-poor sand dunes and serpentine-derived soils. This combination of conditions allowed for a flourishing adaptive radiation of many closely related species….” To the page…
