Bengaluru Rains: Why are trees falling so rapidly? Experts point to poor choices and urbanization

In recent weeks, Bengaluru has witnessed an alarming rise in tree falls across the city, with one fatality reported in Koramangala after a tree collapsed during heavy rains. Trees are toppling not just during strong winds and rain but even in calm conditions, prompting serious concern among citizens and environmentalists alike.

Experts attribute the phenomenon to the widespread planting of exotic, ornamental trees like Tabebuia, Gulmohar, Copper Pod, Rain Tree, and Akasha Mallige. These species, though aesthetically pleasing, have shallow root systems and are not resilient to the impact of heavy rain or strong winds. Their average lifespan is only 30-40 years, after which they become structurally weak and prone to sudden collapse.

Adding to the problem, rampant urbanization has resulted in tree roots being cut during roadworks, drainage installations, and underground cabling. Concrete and asphalt around the base of trees restrict water absorption and weaken their health. Fungal infections often attack these compromised roots, causing the trees to decay from within.

Environmentalists argue that native species like Mahogany, Neem, Honge, Cotton, and Tamarind trees should be planted instead. These species develop deep roots and have a higher resistance to harsh weather conditions, making them safer and more sustainable choices for urban avenues.
