One of the major risks that the proposed Mumbai-Ahmedabad High Speed Rail project poses to the wildlife thriving in the forested patches of the Sanjay Gandhi National Park, Tungareshwar Wildlife Sanctuary in Vasai and Thane Creek Flamingo Sanctuary, as per the Environment Impact Assessment report prepared by the National High Speed Rail Corporation, is poaching by construction workers, a report in this paper said.

This is because construction workers will have access to the forest areas along the corridor. Another concern raised in the report is that the undersea tunnel, to be constructed near the flamingo sanctuary, might have an adverse impact on birds.
