Reef Health Index and Marine Managed Areas
The National Reef Health Index (RHI) was 2.8 (out of 5) or ‘fair’.
Coral cover was good (score=4), suggesting these reefs could
support larger fish populations. Herbivorous fish were common
(score=3), but moderate to small in size. Fleshy macroalgae (score=2)
were abundant in areas without herbivory and could be reduced if
herbivorous fish, especially parrotfish, were protected. Commercial
fish biomass was low (score=2).
