THANE: Thane mayor Sharmila Pimpolkar on Wednesday held an urgent meeting of the Tree Authority Department and ordered a comprehensive survey of dangerous trees across the city.The move comes a day after a tree fell on a school bus in Mumbai, killing a student, and another incident in Thane left a 52-year-old man injured after a tree-related mishap.“Special inspection of trees in schools, colleges, housing societies, hospitals, major traffic roads, public places and areas with high citizen movement should be carried out across the city. Also, a re-survey should be conducted at places where tree branches were pruned earlier to ensure that the condition of the trees remains safe,” the mayor told officials.The mayor directed officials to immediately identify dangerous, dead or leaning trees, as well as large branches that could pose a risk, and take priority action to prevent possible accidents.“Pruned branches lying along roads should be removed immediately as they obstruct traffic movement and increase the risk of accidents,” Pimpolkar said.The mayor also urged citizens to immediately inform the Corporation about trees found in dangerous conditions.
