My current research is focused on documenting the abundance and distribution of the non-native bryozoan, Watersipora subtorquata, on offshore oil platforms and natural reefs within in the Santa Barbara Channel. In 2001, Watersipora occurred on only one of seven platforms surveyed, but in high cover, suggesting that it can become a dominant member of the invertebrate assemblage on platforms. To better understand and manage the spread of this species, our team is using both empirical and modeling results to evaluate dispersal pathways, and conducting field experiments to explore factors influencing invasion success. Expected study outcomes include the development of mitigation measures to manage the spread of Watersipora to offshore structures, including future renewable energy installations, and to natural habitat, and recommendations to inform decommissioning decisions required by the California Natural Resources Agency in a Rigs-to-Reefs Program.
