Our History

For more than 19 years, the Reef Resilience Network has served as a global leader in building the capacity of marine managers to effectively manage, protect, and restore coral reefs and reef fisheries around the world. To achieve this, we connect reef managers and practitioners with peers, experts, and the latest science and strategies, and provide online and hands-on training and implementation support. The Network is a partnership led by The Nature Conservancy that is comprised of more than 5,200 active members, and supported by dozens of partners and TNC staff, as well as 100s of global experts in coral reefs, fisheries, climate change, and communication who serve as trainers, advisors, and content reviewers.
