The bio-restoration works of wetland ecosystems in high Andean areas where the NG and NGL lines of Transportadora de Gas del Perú TGP are laid out consisted of the recovery of natural draining patterns in the Right of Way - RoW, increasing the percolation and seepage capacity, which is necessary for the growth of native vegetation of the ecosystem, thus, increasing vegetation cover in the RoW.
Furthermore, physical barriers were installed to protect the excessive livestock in the region, preventing overgrazing in the RoW, and allowing vegetation to grow.
Local labor participated in these works. They were trained in wetland restoration and management techniques, including the breeding of camelids without affecting the wetland ecosystem.
An increased diversity of species was observed in the transects as they were farther from the pipeline; however, an analysis of the diversity index by Kp and transect does not show a defined pattern, in two of the eight sampling points (Kp 332 and Kp 349), the farthest transects in relation to the pipeline show high diversity indexes as compared to other transects near the pipeline.
