Mumbai faces low survival rate for transplanted trees

The Mumbai Metropolitan Region Development Authority (MMRDA) plans to transplant over 7,500 trees for a car depot linked to the metro 9 corridor in Uttan. However, data shows that the survival rate for transplanted trees is only about 33%. This figure comes from previous metro projects, where many transplanted trees did not survive. In contrast, trees that are planted in their original locations have a much higher survival rate of nearly 90%. The Mumbai Metro Rail Corporation (MMRC) previously removed over 2,800 trees for metro lines and stations. They also transplanted 1,643 trees for other facilities, but only 545 of those survived in a 2020 survey. Experts, including MMRC officials, say that in-situ plantations are far more successful. They highlight that many factors influence the success of transplanted trees. Even under ideal conditions, a 50% survival rate is considered good. Environmental activists raise concerns about the low survival rates. They argue that simply transplanting trees without proper care does not work. Zoru Bathena, an activist, emphasized that the process needs better attention and maintenance. As MMRDA plans the car depot, reports suggest that nearly 10,000 trees may be affected. While a recent public notice claimed that only 3,716 trees would be cut down, MMRDA still aims to transplant around 7,590 trees. Despite these efforts, environmentalists continue to report that even the trees planted on-site have perished, likely due to poor maintenance. Concerns have been raised about the condition of tree plantations, particularly in Aarey Colony, where the car depot was built. Activists call for accountability for the maintenance of these trees, as significant funds are allocated for their care.
