The lack of scientific equipment is to be blamed for the haphazard tree pruning in the city, in which the healthy and not dangerous branches are cut, feel civic officials and activists.
"The civic body has given us just one vehicle with a portable tree-pruning ladder for two zones. This makes the process time-consuming," said Parag Masurkar, assistant commissioner, D-ward.
Last week, residents of Grant Road had submitted a letter to the Brihanmumbai Municipal Corporation (BMC) claiming that the healthy branches in their area, too, were cut owing to the faulty equipment.
According to activists, in most cases, labourers are asked to climb the trees to cut the branches. "We have repeatedly asked the civic ward officials to conduct an audit so that the work can be carried out in a scientific manner. As the labourers can only reach a certain height, we end up losing the healthy branches," said Rajkumar Sharma, an activist from Chembur.
"The highest branch of a full-grown tree is the most vulnerable. It is approximately 12-15 feet above the ground and cannot be reached unless one uses a tree-pruning ladder," said Dr Sharad Chaphekar, chairperson, tree expert committee, BMC.
Kamalashankar Yadav, superintendent, gardens, however, said the professional expertise of the labourers makes up for the lack of equipment. "With their professional expertise, most of our junior tree officers can easily identify the dangerous branches and take necessary action," said Yadav.
