Second synchronised survey of Nilgiri Tahr concludes; sightings in former habitats indicate population recovery, says forest department
Conducted under the ongoing Project Nilgiri Tahr, the large-scale survey was completed on April 27 across 176 survey blocks in 14 forest divisions.
Nearly 800 field staff were deployed, collectively covering around 2,000 kilometres of challenging terrain. According to the release, Nilgiri Tahr were sighted in most survey blocks, with encouraging signs of breeding, as many herds included kids and young individuals.
A particularly notable observation came from the Periyattumalai area in the Coimbatore division, where Nilgiri Tahr were once again spotted after being rediscovered there last year following a decade-long absence, the release said. Similarly, sightings in the newly colonised Pasumalai block in the Chinnamanur range of the Megamalai division indicated healthy habitat recovery.
Notably, seven of the ungulates were sighted at even the lowest elevation, just 240 metres above sea level, in the Peyanar Varaiyattu Mottai block — a dry, thorny escarpment terrain. The survey also recorded pellets in the Mangaladevi block of Megamalai division, where the species was previously thought to have moved out.
As part of the survey, field teams collected Nilgiri Tahr pellet samples and carnivore scat for parasitic analysis. These samples are being prepared for detailed laboratory study at the Wildlife Division of Tamil Nadu Veterinary and Animal Sciences University (TANUVAS). The goal, the department said, is to understand parasitic species and their life cycles in association with the Tahr.
Populations were reported to be especially healthy in the Grass Hills and Mukurthi National Parks — two critical habitats considered key for the survival of the species. Photo documentation from these areas supports the continued importance of these ecosystems.
The survey was led by M. G. Ganesan, Project Director; Ganeshram, Assistant Director; Chendura Sundaresan, Forest Range Officer, along with research personnel and experts from TANUVAS and WWF India.
Top officials including IUCN country representative Yash Veer Bhatnagar, Additional Chief Secretary Supriya Sahu and Chief Wildlife Warden Rakesh Kumar Dogra monitored the survey.

IIT Guwahati team gives bamboo an automobile-ready touch
GUWAHATI A team of researchers from the Indian Institute of Technology Guwahati (IIT-G) have fused bamboo with biodegradable polymers to develop a composite material as a suitable replacement for conventional plastics used in automotive interiors. The cost-effective and eco-friendly composite made from Bambusa tulda, a fast-growing bamboo species grown across India's northeast, has potential applications in furniture, electronics, and packaging industries too, the researchers said. The team said properties such as high strength, thermal stability, and low moisture absorption make the composite a greener alternative to plastics. The findings of the team's research were published in the journal Environment, Development and Sustainability. The paper is co-authored by Poonam Kumari, Professor in the Department of Mechanical Engineering, and research scholars Abir Saha and Nikhil Dilip Kulkarni. The IIT-G researchers tested four bamboo-based composite formulations consisting of Bambusa tulda fibres reinforced with bio-based or petroleum-based epoxies. By treating the bamboo fibres with alkali, the team improved its compatibility with the base polymer, resulting in enhanced durability for real-world use. The developed formulations were then evaluated on 17 different parameters to test their tensile strength, thermal resistance, impact durability, water absorption and cost per kilogram, among others. While these formulations had distinct strengths, none of them possessed all the properties necessary to provide a balanced and high-performing option. To address the issue, the team employed a structured evaluation method known as Multi-Criteria Decision-Making. The team identified the bamboo composite made with bio-based epoxy FormuLite as the best-performing option with low moisture absorption, significant thermal stability, and mechanical strength. 'The cost-effective nature of the composite, priced at ₹4300 per kilogram, makes it an eco-friendly solution for automotive parts, such as vehicle dashboards, door panels and seat backs, among others,' the paper stated. 'The developed composite can be used for designing components/parts in consumer electronics, automobiles, aerospace, sustainable building materials, etc. The product will replace wood, iron, or plastic components and will have similar cost and help fulfil the sustainable development goals,' Dr. Kumari said.

IIT-Guwahati researchers develop bamboo-based composite for greener automobile interiors
NEW DELHI: Offering a practical, eco-friendly substitute for plastic components in cars, researchers at the Indian Institute of Technology (IIT) Guwahati have developed a bamboo-based composite that can be used in dashboards, seat backs, and door panels, combining high mechanical strength with low environmental impact. These composites can even replace plastic or wood parts in electronics, furniture, and building materials The material, made using Bambusa tulda, a fast-growing bamboo species from Northeast India, is reinforced with biodegradable polymers and has demonstrated strong performance in terms of thermal stability, tensile strength, and moisture resistance, key requirements for automotive interiors. The research, led by Poonam Kumari, professor in the department of mechanical engineering, addresses the growing need to reduce plastic waste and transition towards renewable materials in industrial applications. The team tested four bamboo-based formulations using both bio-based and conventional epoxies, evaluating them on 17 parameters including tensile strength, thermal resistance, water absorption, and production cost. To identify the most balanced formulation, the researchers applied a multi-criteria decision-making (MCDM) method, which pointed to a bio-epoxy blend made with FormuLite as the most suitable option. This variant demonstrated high tensile strength (144.76 MPa), significant thermal stability (glass transition temperature of 111.72°C), and the lowest moisture absorption (4.49%). The cost was also competitive at Rs 4,300 per kilogram, making it suitable for components like dashboards, seat backs, and door panels. 'These composites can replace plastic or wood parts not just in automobiles but also in electronics, furniture, and building materials,' said Kumari. 'Their use aligns with India's Green Tech Revolution and Make in India goals, and supports several Sustainable Development Goals.' The team also performed a life-cycle assessment of the material, with plans to scale up production using industrial processes like resin transfer and compression moulding. The research has been published in Environment, Development and Sustainability (Springer Nature), with Kumari co-authoring the paper alongside her PhD students Abir Saha and Nikhil Dilip Kulkarni. The initiative builds on IIT-Guwahati's broader sustainability agenda, reflected in its high ranks in both the NIRF and global SDG-based rankings. With this development, the institute adds momentum to the use of indigenous materials in high-performance engineering applications.
