High in the Western Ghats, where Tamil Nadu's mountains meet the sky, an ancient ungulate is making a quiet comeback. The Nilgiri Tahr—a stocky, sure-footed animal found nowhere else on Earth—now numbers 1,364 individuals across the state, according to the third synchronized population survey released this week by Ministers R.V. Ranjith Kumar and V.K. Rajeev. That's a remarkable 32% jump from just two years ago, when researchers counted only 1,031.
The surge matters profoundly because the Nilgiri Tahr is Tamil Nadu's state animal and one of the world's most endangered mountain ungulates. For decades, habitat loss and poaching pushed it toward extinction. Now, a coordinated conservation effort is reversing that trajectory—a rare victory in an era of species decline.
The survey, conducted from April 24 to 27 across 177 survey blocks in all 14 of Tamil Nadu's forest divisions, was a feat of human commitment. A team of 858 forest officers, scientists, veterinary doctors, and frontline staff trekked 3,219 kilometers through rugged terrain to count every animal they could find. For the first time, they used an Android-based mobile application called "Varudai" to transmit field observations in real time, bringing conservation work into the digital age while staying rooted in the forests themselves.
The tahrs are not spread evenly. Two large, protected populations account for nearly half of the state's total: 360 animals in Grass Hills National Park within the Anamalai Tiger Reserve, and 313 in Mukurthi National Park in the Nilgiris. The remaining 691 live in fragmented habitats across 13 forest divisions—a more precarious existence, but one that reveals the species' adaptability. Tiruppur division leads the fragmented populations with 148 individuals, followed by Kalakad with 115 and Pollachi with 78.
What excites conservationists most are the fresh discoveries. Researchers confirmed Nilgiri Tahrs in five habitat blocks where they had never been documented before: Tiruvannamalai Mottai, Rasivarai, Thoovanam Mottai, and two sites in Kodaikanal division. These sightings suggest the animals are expanding their range, reclaiming terrain lost to human encroachment.
The population structure itself is healthy. The survey found a male-to-female ratio of 55:100 and more than 66 young animals for every 100 females—numbers that indicate thriving breeding populations, not populations barely clinging to survival. Perhaps most striking is the species' vertical resilience: tahrs were recorded from just 270 meters above sea level all the way up to 2,630 meters, suggesting they can thrive across diverse terrain.
The survey was a collaboration that reached far beyond Tamil Nadu's borders, drawing in Kerala's Forest Department, the Wildlife Institute of India, World Wildlife Fund-India, IUCN-India, and several universities and conservation organizations. This web of expertise and shared commitment is itself a conservation model—proof that endangered species don't need to be saved in isolation, but through coordinated, science-based partnerships.
The steady three-year upward trend, officials say, provides a solid foundation for long-term planning. The Nilgiri Tahr's recovery remains fragile, dependent on sustained habitat protection and anti-poaching efforts. But the numbers now tell a different story than they did a generation ago—one of a species that, when given space and protection, chooses to thrive.
