50 Reefs Initiative

A pioneering initiative identifying the coral reefs most likely to be key to saving the ecosystem.

The 50 Reefs initiative was conceived by The Ocean Agency during the filming of the Netflix Original Documentary Chasing Coral. The initiative aimed to identify a global portfolio of coral reefs with a strong chance of surviving the impacts of and reseeding surrounding areas over time.

The scientific study behind 50 Reefs was the first of its kind. It was designed to identify the best places to focus conservation and restoration efforts to help protect the ecosystem most vulnerable to climate change. Since its publication in 2018, the 50 Reefs scientific study has been used by organizations and funders worldwide to improve the targeting of action.

The 50 Reefs approach to targeting action has changed the game in coral reef conservation. It has resulted in over $100 million in new funding to bolster a wide range of conservation efforts to protect and restore the reefs identified. The study is also used by the Global Fund for Coral Reefs to target investments.

50 Reefs was developed by The Ocean Agency in partnership with the Global Change Institute at The University of Queensland and the Wildlife Conservation Society and funded by Bloomberg Philanthropies, The Tiffany & Co. Foundation, and Paul G. Allen Philanthropies.
