Building bridges for India’s wildlife

The Hoolock gibbon population in Northeast India is facing a 90% decline due to habitat fragmentation caused by roads and railways. Experts are advocating for wildlife overpasses to reconnect forest canopies and protect these arboreal primates.
Why it matters
Infrastructure development often conflicts with biodiversity, necessitating engineering solutions to maintain ecological connectivity.

Our increasingly busy highways surely need such facilitators for our wildlife The Hoolock gibbon is India’s only ape other than us humans. Found in Northeast India, mostly to the south of the Brahmaputra river, the western and eastern hoolock gibbon populations have declined by 90% in the last few decades. The main reason for this has been the fragmentation of their habitats — the range that individuals can freely roam over — by roads and railway lines.
