Restoring Presidio's native plants is painstaking process

Extreme biodiversity, coupled with the surrounding extreme urbanism, makes 
the Presidio arguably the epicenter of native plant restoration in the 
West.

The 2.3 square mile park, formerly an Army base, is home to 600 plants, 
more variety than in most states. It owes this biodiversity to its San 
Francisco location, a city at a biogeographic crossroads, even straddling 
two tectonic plates. The city also has diverse topography; microclimates; 
unique geologic formations; and a range of habitats: salt and freshwater 
marshes, seeps and creeks, rocky intertidal zones, chert outcroppings, 
dunes, serpentine grasslands.
