Comparison between the trends for the total number of active wetlands (blue circles) and the total perimeter (black circles) for different censoring levels, \({\mathrm{z}}_{\mathrm{gw}}\), for DEMs of four landscapes. Dashed lines represent the thresholds that were used to compute the emergent ecological network, shown in Fig. 3. The blue and black dashed lines represent the thresholds that maximizes the number of active wetland and the total perimeter, respectively. The red dashed line stands for a censoring level \({\mathrm{z}}_{\mathrm{gw}}>{\mathrm{z}}_{\mathrm{tp}}\).
