Following the designation of MPAs along California's North Central Coast, Ecotrust and Natural Equity established the Monitoring Human Uses and Values project to better understand the influence of MPAs on human activities. We are researching both consumptive (e.g., commercial fishing, recreational fishing, charter fishing) and non-consumptive (e.g., diving, kayaking, whale watching, beach walking) uses of the region. The objectives of this research are to: 1) Provide spatial and demographic baseline estimates of economic activity in the study region; 2) describe the initial responses of ocean/coastal user communities to the MPAs; and 3) inform the planning and implementation of long-term monitoring, in order to understand the causal links between ecosystem features, socioeconomic changes, and the implementation of MPAs.
