Table 2 Unique status assessments considering four reef characteristics (total fish biomass; herbivorous fish biomass; juvenile coral density; structural complexity) overall and at each site. Numbers represent outcomes from the permutation analyses based on two-tailed one-sample t-tests (pooling three ‘5 m depth’ and one ’15 m depth’ transects: df = 3 at the site-level; df = 31 overall; interpreting significance based on 99% confidence intervals); observed mean was significantly higher (1), lower (−1) or not statistically different (0) from the recommended threshold. Last column represents assessment outcomes using the ‘composite resilience index’ expressed on a scale of 0–100%.
