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 and the Gulf of
Farallones National Marine Sanctuary. Goals of the project include: 1) To monitor the rocky intertidal habitat and
develop a baseline database of invertebrates and algal 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; 3) To increase stewardship in the Gulf of
the Farallones National Marine Sanctuary; and 4) To contribute abundance and population data on key algae and
invertebrate species to the national database, LiMPETS (Long Term Monitoring Program & Experiential Training
for Students). Student volunteers complete an intensive 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 two baseline-monitoring surveys three times per
year (fall, winter, and late spring) to identify and count key invertebrate and algae species. Seasonal abundance
of the algae species Mastocarpus and Fucus revealed lower populations in the spring monitoring events. Turban
snails, Tegula funebralis, also showed dramatic population variation with respect to tidal zone. One of our project
goals is to monitor this area long enough to obtain trends and to begin to connect these patterns to contributing
factors (specific weather events, anthropogenic impacts, etc). Replicate counts of all species are regularly
performed. Replicate counts for invertebrate and algae species within the same quadrat along the permanent
transects revealed a very small amount of variability, giving us confidence that our monitoring program is
providing reliable data.
