Rocky Intertidal Monitoring in the San Francisco Bay Area
Why is the Rocky Intertidal Zone Important?
Why Do We Monitor Rocky Intertidal Communities?
- To detect population trends for select rocky intertidal organisms
- To detect trends at multiple scales—from site- and park-wide trends to regional patterns—by contributing this data to the larger MARINe monitoring network
- To better understand normal variations in rocky intertidal communities, and to identify abnormal changes such as overuse, disease spread or oil spill impacts
How Do We Use the Monitoring Data?
- To inform decisions about issues like coastal access, over-harvest, oil spill clean-up and endangered species (e.g. black abalone) recovery
- To study the effectiveness of California’s new Marine Protected Areas
- To assess and forecast the effects of climate change on rocky intertidal species
