According to environmental safeguards directed by the National Green Tribunal for the Great Nicobar Island project, which ecological feature must be protected along the coastal stretch?

The National Green Tribunal directed authorities implementing the Great Nicobar Island project to ensure the protection of coral reefs along the coastal stretch. Coral reefs are ecologically sensitive marine ecosystems that support marine biodiversity and act as natural coastal protection barriers. The tribunal also instructed that coral regeneration should be carried out through scientific methods if any reef damage occurs. These safeguards form part of the environmental conditions attached to the project’s Environmental Clearance to minimise ecological disturbance during construction and infrastructure development activities.
