Reef

Coral reefs provide some of the most valuable ecosystem services for the islands. They are a driver of tourism, they protect against storms, and support local fisheries. To follow the health of the coral reefs a number of locations on each island are photographed each year, providing a systematic snapshot of ecosystem health and insight into temporal trends in reef condition. The data contribute to our understanding of processes shaping coral reefs, and to actionable advice to policy makers, stakeholders, and communities.The Global Coral Reef Monitoring Network method (GCRMN) is used on St.Eustatius while Bonaire and Curacao have been using this method since 1973.
