Site optimization process applying conservation reserve design strategies based on: (a) Maximum coverage problem (selection of 250 sites) and (b) Minimum set problem (selection of the minimum number of plots that allow including 80% of the species, represented by dashed line). Optimization has been performed in both cases employing different optimizers, including species richness, range rarity richness (RRR), corrected range rarity richness (CRRR), Shannon‐Wienner diversity index (Shannon), Simpson diversity index (Simpson), the turnover component of beta diversity, or pairwise Simpson dissimilarity index (Simpson beta), the most frequent plots selected in 1,000 iterations with a randomized starting seed using the pairwise Simpson dissimilarity index (frequent), and the plots selected with a randomized seed using the pairwise Simpson dissimilarity index (SimpsonBeta_random seed)
