The geography, climate and geology of the Presidio result in a complex natural history and a rich diversity of life. It is a unique world within a world. From birds to plants the ecosystems here can be found in few places on the planet. 

These small islands of life are always at risk. A seemingly insignificant act … like picking a flower … can affect the plant for a year. 

A thoughtlessly tossed plastic bottle will still be around a half-century later.
