Greater Bengaluru Authority receives over 1,500 objections to tree felling for Hebbal Short Tunnel

The Hebbal Short Tunnel Project is a proposed infrastructure project in Bengaluru. The article does not explain its transport purpose or provide engineering details. It does state that the project’s alignment requires action involving 1,128 trees, which is why the Greater Bengaluru Authority invited objections to their proposed felling.

The concern is not only the number of trees. Residents and activists questioned the project’s effects on species diversity, microclimate, hydrology and the area around Hebbal Lake. The Bangalore Development Authority is the implementing agency and must explain why the trees need to be felled. A tree expert committee will review the proposal and conduct a joint site inspection with the BDA.

The project cannot proceed with tree felling for now. The National Green Tribunal has restrained the BDA from cutting trees until the case is heard, with the next hearing scheduled for December 15. Any later decision must follow that outcome.

The proposal covers 1,128 trees for the Hebbal Short Tunnel Project. The Greater Bengaluru Authority invited objections on September 20 and initially set a 10-day deadline. Residents and activists responded with more than 1,500 objections, making the public response larger than the number of trees proposed for clearance.

GBA sources said over 700 objections arrived during the first window. The remaining submissions came before the final deadline. Many objections were detailed. They listed tree species, discussed biodiversity, and examined issues such as microclimate, hydrology near Hebbal Lake, tree size and heat-island risk.

The GBA is filtering and grouping the objections by theme. It will send them to the tree expert committee and the BDA. The BDA must review the concerns, explain the proposed clearance, and join a site inspection. The NGT’s restraint currently prevents any felling.

People argue that the trees form an important ecological space, not merely a collection of individual plants. Objections focus on species diversity and the loss of many trees at once. Residents also say the area functions as a key lung space, so removing trees could affect local environmental conditions.

Several submissions discuss microclimate, meaning the local conditions around temperature, shade and air movement. Others raise hydrological concerns because the proposed alignment is close to Hebbal Lake. Some objections assess the size of particular trees and warn that clearing the area could increase the risk of it becoming a heat island.

The GBA is grouping these concerns before sending them to the tree expert committee and BDA. The committee and BDA will inspect the site together. Their review must consider the objections before any decision on felling or translocation. The NGT has paused felling until December 15.

The National Green Tribunal, or NGT, is a specialised Indian forum for environmental disputes. It examines challenges involving environmental protection and can issue directions while a case is pending. Here, the case challenges tree felling connected with the Hebbal Short Tunnel Project.

The NGT has restrained the BDA from felling any trees until the hearing is completed. The article gives December 15 as the next hearing date. This restraint does not cancel the tunnel project. It temporarily prevents the proposed tree clearance while the tribunal considers the challenge.

The immediate effect is a pause in tree-felling work. The GBA and BDA can still process objections and prepare their responses. After the hearing, further action depends on the tribunal’s outcome. The BDA must also follow the tree expert committee’s review and any applicable decision before clearing or translocating trees.

The Greater Bengaluru Authority is managing the objection process, while the Bangalore Development Authority is the project’s implementing agency. A tree expert committee has the central review role. The article says the committee must decide what happens to the trees, whether that means felling or translocation.

The GBA is filtering objections into themes and will forward them to both the committee and the BDA. The BDA must review the concerns and explain why the trees need to be felled. Committee members and BDA representatives will then conduct a joint inspection of the project site.

No final tree decision has been reported. BDA Chairperson N.A. Haris previously said that 56 trees would be felled and the rest translocated, but a GBA officer clarified that the tree expert committee must decide. The NGT’s restraint also blocks felling until the case advances.

Moving trees instead of cutting them could reduce immediate loss of vegetation, especially when healthy trees can be relocated successfully. It may retain some shade, habitat and landscape value. However, translocation is not a perfect substitute for leaving trees where they grew. Large trees can suffer root damage, transplant shock and later decline, while moving them may disrupt existing soil, wildlife and water relationships.

The article gives a specific alternative: BDA Chairperson N.A. Haris said only 56 trees would be felled and the remaining trees translocated. A GBA officer clarified that this was not final. The tree expert committee must decide whether trees are felled or moved.

The NGT has stopped all felling until the case is heard. If clearance is eventually allowed, the BDA must plant 10 trees for every tree cleared, regardless of whether trees are translocated or felled. The article does not state translocation’s likely success rate.

Urban trees provide living space and food for birds, insects and other organisms, supporting biodiversity. Their shade and water release can cool nearby areas, while roots help slow and guide rainwater through soil. Trees also improve the quality of urban spaces and can support people’s physical and mental well-being. These are established environmental effects beyond the article’s specific project details.

The objections reflect several of these roles. Residents submitted species lists to show biodiversity, discussed microclimate effects, and raised hydrological concerns because the alignment is near Hebbal Lake. They also warned that the area could become a heat island after tree removal. The area is described as a key lung space.

The GBA is sending these concerns to the tree expert committee and BDA. Their joint inspection will examine the proposal. The article does not quantify health effects, temperature changes or water-flow changes, so those impacts remain concerns rather than reported measurements.

The NGT’s restraint immediately prevents the BDA from felling trees for the project. This can affect the project timeline because tree clearance cannot proceed before the next hearing on December 15 and the tribunal’s consideration of the challenge. The order pauses felling, but the article does not say that the entire project has been cancelled.

The more than 1,500 objections add a substantial review task. The GBA is sorting them into themes, including biodiversity, microclimate, hydrology, tree size and heat-island risk. It will send them to the tree expert committee and BDA. The BDA must respond and join a site inspection.

The eventual outcome remains open. The committee may assess felling or translocation, while the tribunal’s ruling will determine what can happen next. If trees are cleared, the BDA must plant 10 trees for every tree cleared. The number ultimately felled is therefore not settled.
