How this reef is doing
ⓘ How we measure thisReef state
Inside this fully protected sanctuary reef fish biomass reaches about 879 grams per square metre, among the highest in the Tropical Eastern Pacific and dominated by large predators (Quimbayo et al. 2016); the state shown reflects coral under recent heat stress rather than the fish community.
Coral cover
Fish life
More fish than a healthy reef of its kind.
