CONCLUSIONS
Management should focus on reducing human‐induced changes that reduce reefs’ ability to recoverchanges that reduce reefs ability to recover
Conduct studies to identify additional resilient sites and determine how coral communities are able to grow in these resilient sites
Design network of protected areas that incorporate resilient sites
All efforts should focus on reducing CO2 emissions
resilient sites
All efforts should focus on reducing CO2 emissions throughout the world
