Coastal Serpentine Scrub

Coastal Serpentine Scrub 
Community
Will Eldeer, NPS
 

The coastal scrub community on the Presidio is largely a unique serpentine variant of coastal scrub that includes the vestigial remnants, such as Raven's manzanita and California lilac, of a serpentine chaparral community. This shrub-dominated community is found on gentler slopes than those containing the bluff scrub community and mostly occupies serpentine outcrops with shallow soils and of limited local extent. The community supports many rare plants, including Raven's manzanita, which may have been the historically dominant shrub in a no longer extant serpentine chaparral community.

Typical Sites at the Presidio: Less steep parts and top of the coastal bluffs north of Baker Beach and the bluffs near Fort Point and behind Crissy Field.
