Coral reefs are critical for tourism, coastal protection, food supply, and millions of jobs in The Caribbean. The Nature Conservancy and partners, using innovative technologies, developed these maps to advance coral restoration, climate adaptation, and ocean protection for the 44 million people who call the Caribbean home: Caribbean-wide maps of coral and seagrass to guide marine protection, coral climate refugia models to guide investments in coral restoration and conservation to the reefs most likely to survive the impacts of climate change, and high-resolution maps of live coral cover and reef rugosity to guide coral restoration to areas most suitable for coral growth. These models are informed by extensive field validation and are already guiding conservation actions across the Caribbean.
