The pallid manzanita (Arctostaphylos pallida) is the rarest plant in the Sausal Creek Watershed—a State-listed endangered and Federally-listed threatened plant. Since 1998, volunteers have worked to ensure the survival of the two colonies of pallid manzanitas within the watershed through brush clearing, monitoring, and advocacy.

Pallid Manzanita Restoration Crew Volunteers are asked to commit to working six days over the course of a year so we can train and retain people who will be knowledgeable about working with this vulnerable species.


To volunteer, contact our Restoration and Nursery Manager at
