Coastal Dune Scrub Community
The dune scrub community is found on inland dunes landward of the foredune community. It is characterized by densely-packed shrubs interspersed with scattered areas of grasses, wildflowers, and open sand. The dune scrub community is represents several stages of ecological succession that follow disturbances such as fires or dune blowouts. Dune blowouts are areas where high winds may reactivated the dunes, causing sand to blow out and uprooting vegetation in the area; new dunes may also form and cover an established dune community if the blown out sand is deposited in a localized area. Urban encroachment and the introduction of non-native plants has greatly reduced the extent of the dune scrub community in San Francisco, where it once covered 14 square miles.
Typical Sites at the Presidio: Feral Dunes, Lobos Creek Valley, North Baker Beach, Crissy Field, and Presidio Hills.
