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.
