The Sustainable Seas Student Monitoring Project at the Branson School in Ross, CA has monitored Duxbury Reef in Bolinas, CA
since 1999. In cooperation with the Farallones Marine Sanctuary Association, goals include: 1) To monitor the rocky
intertidal habitat and develop a baseline database of density and abundance; 2) To contribute to the conservation of the
rocky intertidal habitat through education of students and visitors about intertidal species and requirements for maintaining
a healthy, diverse intertidal ecosystem; and 3) To increase stewardship in the Gulf of the Farallones National Marine
Sanctuary. Student volunteers complete an intensive 22 hour training course on the natural history of intertidal
invertebrates and algae, identification of key species, rocky intertidal ecology, interpretation and monitoring techniques,
and history of the sanctuary. Students conduct four baseline monitoring surveys three times per year (fall, winter, and late
spring) to identify and count key invertebrate and algae species. During 2000-2002, the density of black turban snails,
Tegula funebralis, is lowest in the high intertidal zones in winter yet has little seasonal variability in the mid intertidal
zones. Most algae species had consistently higher percent cover in the northern transects than the more accessible southern
transects. To test the reliability of the student counts, replicate counts of all species were performed. Replicate counts
for invertebrate species within the same quadrat along the permanent transects revealed a very small amount of variability,
giving us confidence that our monitoring program can provide reliable data. Student volunteers helped to design and install a
rocky intertidal information kiosk to greet visitors at the entrance of Duxbury Reef. The kiosk includes pictures and
natural history information on key intertidal species as well as tidepooling etiquette. Students lead an annual celebration
at Duxbury Reef and lead intertidal walks for the public.
