Hebbal Tunnel Plan Sparks Outcry: 1,128 Trees Face Axe

A proposed 2.3-kilometer tunnel project in Bengaluru's Hebbal area has ignited controversy, with plans to cut down 1,128 trees. These trees are located along Ballari Road, the Veterinary College campus, and the vicinity of Hebbal Lake. Residents have voiced strong objections, pointing out that crucial details about tree species and exact locations are not readily available on the civic body's website, hindering their ability to file formal objections.

A recent citizen-led survey documented a rich biodiversity along the proposed tunnel's alignment. This documentation includes nearly 40 native tree species and over 20 other varieties, such as mature banyan trees estimated to be a century old. These native fig trees are vital for local wildlife, providing essential food and habitat for insects, birds, and small mammals. The survey also highlighted the ecological importance of the green corridor between Hebbal Lake and the Veterinary College campus, which serves as a critical roosting space for numerous bird species.

The Bangalore Development Authority is executing the project, which involves constructing an underground road using the cut-and-cover method. Concerns have been raised about the impact on groundwater recharge, especially in hydrologically sensitive areas where mature trees with extensive root systems are being removed and surrounding areas are being concretized. The loss of these large, mature trees, particularly those on institutional campuses, is seen as irreversible in an urban environment with limited green space.
