HMSC Research Seminar-Linking models and data for adaptive management of Marine Protected Areas

Speaker: Will White, Department of Fisheries and Wildlife, COMES, Oregon State University

Topic: Linking models and data for adaptive management of Marine Protected Areas

Marine protected areas (MPAs) are an increasingly common conservation and management tool worldwide. Typically, managers expect that previously fished populations will steadily increase inside MPAs as they return to unfished levels. However, the expectation of a steady, positive increase in population density inside MPAs is complicated by two factors: A) the expected increase depends on the level of fishing pre-MPA, which is usually unknown, and B) high variability in larval recruitment to populations in MPAs makes population trajectories variable.  I use examples from southern and central California MPAs to show how we can use dynamic and statistical models to address these problems. First, I show how to estimate the pre-MPA fishing rate and make short-term forecasts for population trajectories. Then, in a more data-limited case, I show how statistical models reveal the strong influence of larval recruitment variability on overall fish abundance inside MPAs, but how MPA effects are still revealed by population size structure. Together these approaches can help guide short-term management decisions in an uncertain and highly variable coastal environment.
