On September 10, 2025, Eshwar B. Khandre, the Forest, Ecology, and Environment Minister of Karnataka, declared an 8.61-acre area of the Cantonment Railway Colony in Bengaluru as a Biodiversity Heritage Site. This designation is grounded in the Biological Diversity Act of 2002, specifically under Section 37.

Key Details of the Declaration:

• Ecological Importance: This site is crucial for urban ecology, providing essential ecosystem services such as air purification and habitat for diverse flora and fauna. It also serves as a lung space for Bengaluru, contributing significantly to reducing carbon dioxide levels and mitigating air and noise pollution.

Historical Context:

• The site holds historical significance, notably as a location where Mahatma Gandhi engaged with freedom fighters in 1920. Such heritage coupled with its ecological value prompted public interest in preserving the area.

Public and Government Interaction:

  • In total, about 15,000 citizens expressed their desire to preserve the trees and protect the Biodiversity Heritage Site.
• The government received only two objections regarding the proposal, which highlighted the strong public sentiment in favor of conservation.

Government Initiatives:

• The Biodiversity Board engaged the community, inviting suggestions and objections, reflecting a commitment to democratic engagement in environmental decision-making.

Implications of the Declaration:

• The decision to designate the site as a Biodiversity Heritage Site is seen as a progressive step in combating the decline of Bengaluru’s green cover amid concerns over deteriorating air quality and climate change.
• The Minister emphasized the importance of this historic decision in the context of global climate challenges, stating that it is imperative to conserve such natural resources to ensure ecological resilience.
