THANE: More than 105 empty nests have been removed from trees that will be transplanted due to the Wadala-Ghatkopar-Kasarvadavali Metro 4 project.This is the first time in Mumbai that relocation of birds affected by the Metro project was taken into consideration before axing or transplanting trees. Last month, the Thane forest department and MMRDA officials, along with NGO Resqink Association for Wildlife Welfare (RAWW), had conducted a survey on the 11km stretch between Teen Hath Naka and Kasarvadavali, and identified more than 80 nests, of which 60% were found to be empty. “Since Wednesday, we have removed 105 empty nests, but there are still few nests left. We are monitoring these nests; if we find birds frequenting them, these trees will be marked. Then a decision will be taken on whether to relocate the trees now or later after the nests become empty,” said Pawan Sharma, RAWW founder.“We will continue removing empty nests on Friday too,” he added.
