Evaluating Management Strategies to Optimize Coral Reef Ecosystem Services
Scientists from NOAA’s Pacific Islands Fisheries Science Center, Hawai‘i Division of Aquatic Resources, and The Nature Conservancy evaluated how different management strategies would benefit the coastal marine ecosystem and coral reef health at Puakō, in Hawai‘i.
Earlier declines in marine resources, combined with current fishing pressures and devastating coral mortality in 2015, have resulted in a degraded coral reef ecosystem state at Puakō in west Hawaiʹi. Changes to resource management are needed to facilitate recovery of ecosystem functions and services. We developed an ecosystem model to evaluate the performance of alternative management scenarios at Puakō in the provisioning of ecosystem services to human users (marine tourists, recreational fishers) and enhancing the reef's ability to recover from pressures (resilience). Outcomes of the continuation of current management plus five alternative management scenarios were compared under both high and low coral-bleaching related mortality over a 15-year time span.
