The observation came after the counsel for PWD told the Tribunal that it was not possible for it to save or transplant trees that will be felled during construction of elevated road project.
A bench, headed by NGT chairperson Justice Swatanter Kumar, directed both the departments to file a proper affidavit in this regard within two weeks from today.
"It is clear from the records and even as now admitted by Mr Buxy, Conservator of Forest, that the Department of Forest and PWD both have failed to adopt proper methodology for transplantation of trees which they had already transplanted. This has resulted in dual damage.
The Tribunal, however, allowed the cutting of trees by Forest Department along the elevated road project saying the entire process would be videographed.
"In the interest of the project, we permit the Department to transplant or remove the trees if it is absolutely essential but would maintain due records thereof and videography," the bench said.
