The death of nearly 25 full-grown trees, which were uprooted to make way for the Metro 2A (Dahisar to DN Nagar) project and later transplanted near Aarey Colony, has compelled the civic body to come up with a new solution to save the city's full grown trees.

After encouraging citizens to take home small trees and shrubs, the BMC is now inviting housing societies to 'adopt' 20 to 30-ft-tall, mature trees, which would otherwise have come under the axe to make way for infrastructure projects around the city. Over five housing societies in the western suburbs have already shown interest in adopting the huge trees.
