Figure 1 The “Effectiveness” of Coral-Reef Conservation as Measured by the Percent Difference ±95% C.I. in the Total Biomass of Commonly Targeted Reef Fishes between Managed or Conserved Reefs and Matched Control Reefs Where No Conservation or Management Was Imposed Large positive percentages suggest a highly effective conservation result. Confidence intervals were calculated from means of replicate study sites located within each set of managed and control reefs. Site means were calculated from four to six transects within each site. The number of replicate sites sampled within management and matched control reefs are listed in the order presented in Table 1.
