Scientists used a network of interdisciplinary studies to investigate the ecological effects of marine managed areas (MMAs) dispersed widely across the tropics. The results indicate that rigorously enforced MMAs can be an effective management tool to reduce overuse of natural resources and conflicts among different uses of the ocean. In addition, MMAs can provide important data for adaptive management of marine resources.

Effective local management of coral reefs has a direct effect on reducing threats and improving overall coral community health. Careful zoning and effective enforcement of resource use within a marine managed area reduces impacts of overfishing, allowing populations of grazing fish to rejuvenate and maintain healthy ecosystem functioning.
