Tunnel plan threatens Bengaluru's 199 bird species
11 Nov
Summary
- Nearly 200 bird species documented near proposed tunnel alignment.
- Over 1,100 trees marked for removal, impacting habitats.
- Project raises concerns over biodiversity, pollution, and heat.
A decade-long record reveals 199 bird species inhabiting the area of Bengaluru's proposed Hebbal Short Tunnel alignment. Ecologists documented vulnerable species such as the greater spotted eagle and spot-billed pelican. The rapid environmental impact assessment was conducted by researchers from Azim Premji University, utilizing data from 2016 to 2026.
The proposed 2.28-km underground tunnel road, designed to pass through northern city green spaces, faces environmental scrutiny. 1,128 trees along the corridor are designated for removal. These trees, comprising 92 species, are vital for local wildlife, providing habitats and ecological corridors.
Environmental consequences of tree removal include habitat fragmentation, loss of carbon sequestration estimated at 77 metric tonnes, and increased urban heat island effects. The report cautions that even transplantation efforts may not preserve the trees' ecological benefits. The Bangalore Development Authority states it is working to minimize environmental impact and maximize tree retention.
