Why do so many trees fall in Delhi? Experts have a theory

After a day ‘Heavy’ category thunderstorms hit the city On Monday, the Lutheran Deli sidewalks and sidewalks were still lined with broken tree branches and trunks and completely uprooted trees.

A total of 77 trees fell and 58 damaged branches were counted under the New Delhi Municipality (NDMC) according to the Horticultural Wing. On the Ashoka Road, which is covered with jumbo trees, the branches of the thick jumbo tree on the Tolstoy Marg Median were snatched away as branches hung over two separate cars. The plucked, pruned Nem tree completely closed the Jantar Mantar road, with its roots in the air.

Weak roots due to moisture may be the cause of the trees’ growth, says ecologist CR Babuu. “Trees do not easily fall off if there are proper root growths in the soil. Most trees have ‘feeding roots’ in the upper part of the soil. These roots absorb nutrients and moisture, and have symbiotic fungi around and around them. “If the area around the trees is covered with concrete, there will be no life under the concrete.” “The sails of the trees are also not properly handled. If the top is heavy and the roots are not well developed, how can the tree withstand the wind? Different species have different carrying and carrying capacity,” he added.

The 2013 NGT Order states that concrete within 1 m radius trees must be removed. A.D. The Department of Forestry has issued a notice in 2019 stating that tree breeding is affecting all departments and civic agencies and is a breach under the Deli Forest Conservation Act, 1994. The notice also requires agencies to delete trees manually.

Most of the events took place in the capital, Central, New Delhi, and northern districts.

“Leaving 1 meter around trees is not enough to grow street trees. They should have good feed roots that can be distributed to absorb nutrients. But there are limitations considering the width of the sidewalk,” said Professor Babuu.

Navnett Srivastava, DCF, West Division, “If the tree is suspected from all angles, it is more likely to fall. It can cause big trees to fall.

“At the center of the road are trees growing in small areas, such as shisha and silk cotton, which are surrounded by concrete. How do the roots expand? In the long run, the roots spread sideways. It creates pressure, which means the sails are large, but the root cannot withstand the pressure.

Some trees in the Lutheran Delhi area began to be planted in the 1930’s, says environmentalist Prady Crisch. Neem trees have thick bark, “One of the reasons for the fall of trees is that our water table is shrinking and it may be that the trees with the roots are not in contact with water. Another reason could be sidewalk cement. But we are estimating it without proper research.

“If we plant a Delhi native tree and make a difference when we plant Avenue trees, survival and sustainability will be easier. Age is one of the reasons. So as the trees get older, you start planting new species of different species.” MCD offices received 155 complaints from 9 a.m. to 3 p.m.
