Coastal Prairie -
Serpentine Grassland Community

Coastal Prairie was historically the most common plant community in San Francisco and the Presidio. This grass and herb community is found on coastal terraces where soils are well-developed. Serpentine grasslands have a similar composition to the coastal prairie, but have the addition of the rare serpentine endemic species listed below. Today, this community on the Presidio is mainly limited to the area around Inspiration Point.

Typical Sites at the Presidio: Some terrace areas at the top of the coastal bluffs and the Inspiration Point area.
