New research suggests a different approach to protecting reef-building corals

Current fishing and pollution regulations don’t help corals cope with climate change, study says.
By University Communications, Monday, February 18th, 2019
A new study from the University of North Carolina at Chapel Hill reports that protecting coral reefs from fishing and pollution does not help coral populations cope with climate change. The study also concludes that ocean warming is the primary cause of the global decline of reef-building corals and that the only effective solution is to immediately and drastically reduce greenhouse gas emissions.
The new study published in the Annual Review of Marine Science (accessible via MarXiv: https://marxiv.org/ugk4v) found that coral reefs in areas with fishing and pollution regulations had the same level of decline as the coral reefs in unprotected areas, adding to the growing body of evidence that managed resilience efforts, like fishing and pollution regulations, don’t work for coral reefs. This finding has important implications for how to protect reefs and best allocate scarce resources toward marine conservation.
Ocean warming is devastating reef-building corals around the world. About 75 percent of the living coral on the reefs of the Caribbean and South Florida has been killed off by warming seawater over the last 30 to 40 years. Australia’s Great Barrier Reef was hit by extreme temperatures and mass bleaching in 2016 and 2017, wiping out roughly half of the remaining coral on the Great Barrier Reef’s remote northern section.

The study’s authors, led by John Bruno who is a marine ecologist in the College of Arts & Sciences at the University of North Carolina at Chapel Hill, performed a quantitative review of 18 case studies that field-tested the effectiveness of the managed resilience approach. None found that it was effective. Protecting reefs inside Marine Protected Areas from fishing and pollution did not reduce how much coral was killed by extreme temperatures or how quickly coral populations recovered from coral disease, bleaching and large storms.
