Around 284 fully grown trees near the Metro Line 3 car depot in Aarey Milk Colony are under threat after water from a nearby stream was allegedly blocked, leading to severe waterlogging around the plantation area. Environmentalists have warned that the stagnant water could kill hundreds of trees, many of which were part of the compensatory afforestation done to replace those felled for Metro projects in Aarey.

Recently, the Supreme Court had criticised the Maharashtra government over the poor survival rate of trees planted as part of the compensatory afforestation drive, noting that only about 50 per cent of over 20,000 saplings had survived.
