Efficacy to meet conservation targets of biodiversity surrogates as the area of conservation network increases. Results are shown by hydrologic region and for the accumulated solution
at country level. In each curve, the first dot represents the number of planning units that are irreplaceable (selected 100% of the times). The second, third, and fourth points represent
the first, second and third quartiles from the selection frequency values of planning units of extreme, high and medium priority, respectively. This data is derived from the best solution.
