Effectiveness of Local Protection

Caption

Results of a meta-analysis of published studies measuring the effectiveness of local protection [i.e., marine protected areas (MPAs)] in reducing the effects of large-scale disturbances on (a) the loss in absolute coral cover, based on predisturbance coral cover minus postdisturbance cover (i.e., resistance) and (b) the postdisturbance increase in absolute coral cover (i.e. recovery rate). Table 1 lists and describes the component studies. From each study, we recorded the mean disturbance impacts (coral cover per year) and recovery rates (percentage change in coral cover per year). We extracted values presented in a figure (as opposed to in a table or in the text) using the ImageJ tool developed by the National Institutes of Health. All analyses were performed in R.
