This file shows the 6 country level charts and data (large charts) as well as the multiple subregional charts and data found within each country. Coral reef health is measured using four indicators: coral cover, fleshy macroalgae, herbivorous fish and commercial fish. The Coral Reef Health Index (RHI) is the average of the four indicators. Each indicator is assessed at the country and regional level for a given year resulting in a score from 0 and 5 and a grade ranging from Very Good to Critical.
