Delhi-Dehradun Expressway Wildlife Underpasses Work

A 40-day field study by the Wildlife Institute of India recorded over 40,000 wildlife detections across 150 camera traps, proving that the dedicated corridors are being actively used by a variety of species.

While ungulates like Nilgai and Spotted Deer were early adopters, the study also captured movement from elusive predators including Leopards and Rusty-spotted cats, indicating successful behavioral adaptation to the new structures.

The report highlights that despite significant human and vehicular presence, many species, particularly leopards, have adjusted their activity patterns to become largely nocturnal to avoid disturbance.

The underpasses serve as a vital link within the Shivalik elephant corridor and the Rajaji Tiger Reserve, effectively mitigating the "barrier effect" usually created by major highway infrastructure.
