Service Description: The U.S. Virgin Islands are home to a variety of coral reef ecosystems that range in condition, diversity, and resilience to stressors such as fishing, climate change, and pollution. Local managers and decision makers tasked with coral reef conservation urgently need to know where the best examples of corals reefs are, how many of them are protected, how resilient they are, what the greatest threats are, and which reefs can be improved by targeted management actions. The GIS data contained here were compiled by scientists from the National Centers for Coastal Ocean Science (NCCOS) in order to provide a data-driven decision support framework and spatial tool to support marine managers across the U.S. Virign Islands.
