Abstract

Historical declines in marine resources combined with the recent devastating coral bleaching event in 2015 and current fishing pressure have resulted in a degraded coral reef ecosystem state at Puakō, West Hawai'i. Here, we developed a customized ecosystem model to evaluate the performance of current and alternative resource management scenarios in the provisioning of ecosystem services to human users (marine tourists, non-commercial fishers) and enhancing the reef's ability to recover from pressures (resilience). We found current management to be the poorest performer, indicating that changes to resource management are needed to facilitate recovery of ecosystem function and services enjoyed by the local community. We also found that no alternative management solution simultaneously promoted recovery of ecosystem stability while also maximizing the delivery of ecosystem services. However, by elucidating tradeoffs and evaluating a range of potential management options, this study serves as an important decision-support tool and provides a "big picture" context as we move toward ecosystem-based management in the region.
