San Francisco is located in a global biodiversity hotspot - we have rich biological diversity but also a lot of current and potential impacts. Despite being 95% developed, our city contains dozens of natural ecological communities, harboring an astounding diversity of birds, mammals, reptiles and amphibians, rare and endangered species, and over 500 local native plants. We celebrate our diversity, but it is also under serious threat.
