After mid-day highlighted how trees planted by the state last year had withered in neglect, the forest department has decided to use geo-tagging to track each of the 4 crore saplings it plans to plant this year. Geo-tagging will make it easier to get details about the locations and the agencies taking part in the statewide plantation drive.
