With profound sorrow, Wildlife Trust of India mourns the passing of Dr. Ajith Kumar, an eminent wildlife biologist whose contributions to conservation in India have left an indelible mark on the field. A mentor, researcher, and educator, Dr. Kumar dedicated his life to the study and protection of India’s rich biodiversity, inspiring generations of conservationists to follow in his footsteps.

Dr. Kumar’s career spanned over four decades, beginning with his pioneering research on the lion-tailed macaque in the Western Ghats. His work highlighted the critical importance of preserving large, contiguous forest landscapes for the survival of this endangered primate. His contributions extended far beyond primatology, encompassing rainforest ecology, small carnivore studies, and habitat conservation across India.

As a respected scientist, Dr. Kumar played a pivotal role in capacity building for wildlife conservation in India. He led the Master’s Program in Wildlife Biology and Conservation at the National Centre for Biological Sciences (NCBS), where he mentored and trained numerous students who have gone on to shape conservation efforts nationwide. His emphasis on rigorous scientific research, combined with a deep passion for the natural world, made him a guiding light for aspiring ecologists and conservationists.

Beyond academia, Dr. Kumar’s impact was felt in the field, where his insights helped shape policies and conservation strategies for India’s forests and wildlife. His dedication to understanding the impacts of habitat fragmentation and his advocacy for evidence-based conservation practices have left a lasting legacy.

Vivek Menon, founder and ED, WTI, shared a personal reflection on this tragic loss, “Ajith was an exceptional wildlife ecologist and teacher who led an exemplary life in the field, walking forests and hiking mountains with his students. He passed away like he lived, with his boots on. What I would like to remember of Ajith is a kind man who shared all he had with those around him; his innate wisdom, his explosive laughter, his gentle ribbing, his love of good food and drink. And between bouts of all that a fierce passion for science and a yearning for exploring all that nature has yet to reveal to us.”

“We worked together for 25 years. I was the black sheep – a historian among scientists, and a social scientist among wildlife experts. Despite the strong personalities and opinions around me, I credit Dr. Ajith, Director Vijayraghvan, and Dr. Karanth of WCS for giving me the freedom to teach as I saw fit. Dr. Ajith was the one we turned to day in and day out to solve the many problems we faced, especially in a new MSc program. He knew every student, both past and present, and was deeply aware of their strengths and weaknesses. His invaluable guidance helped me navigate my first teaching job in India and my first time teaching scientists. A great researcher, an unmatched mentor, tutor, and a fine friend. Ajathashatru – the one with no foes, and those who disagreed with him were disarmed by his wit and humour. He will be deeply missed by all of us who knew him but his memory will endure. Go well, Dr. Ajith!” expressed Dr. Mahesh Rangarajan, Trustee, WTI.

Prof. B. C. Choudhury Senior Advisor – Aquatic Realm, WTI, reflected on Dr. Kumar’s contributions— “After his seminal work on the lion-tailed macaque and a Ph.D. from Cambridge, Ajith joined the Wildlife Institute of India (WII) and brought attention to the conservation of the Western Ghats, rainforests, and primates. He was instrumental in introducing computer technology at WII and establishing its computer lab. His planning also contributed to the development of WII’s wildlife library. Ajith played a major role in bridging the gap between wildlife biologists, researchers, and managers, a role he continued in his later work at SACON in Coimbatore.”

James Zacharias Sr. Advisor, WTI, expressed his deep sorrow,  “Ajith, undoubtedly one of the best wildlife scientists in the country, was at his best when he was out in the field with his students. I was lucky to have taken part in many of his field trips which involved long hours of walking. I was always amazed by the bond he shared with his students.”

“Teacher—this word embodied Dr. Ajith Kumar in every sense. It didn’t matter if he taught you personally or where you were from; he was always there with his wisdom, knowledge and humour. He was there for me during one of the toughest times in my life and supported me, pushing me to be where I am, without judgment, even when we hadn’t spoken in years. Always helpful and supportive, I never heard the word ‘no’ from him… he will be missed more than words can describe, expressed Dr Bindu Raghavan, Head—Wild Rescue, WTI

Dr. Ajith’s passion and contribution to wildlife are irreplaceable, and his sudden demise is a great shock and loss to the entire wildlife fraternity and to everyone who knew him. There was no better mentor or friend than Dr. Ajith—his guidance, enthusiasm, and support were always available to us, no matter how big or small the problem. He taught us how to work hard, enjoy life and push through the difficult times. Words will never be enough to describe his dedication to wildlife and we will try our best to take his legacy forward in the best possible way. His absence will leave a void, but we will carry his spirit with us Dr. Tanushree Srivastava, Manager & Head, Western Himalaya Mountain Ungulate Project, WTI

Dr. Ajith Kumar’s passing is an immense loss to the conservation community. His wisdom, humility, and unwavering commitment to wildlife protection will continue to inspire those striving to safeguard India’s natural heritage. We extend our deepest condolences to his family, colleagues, and students. His legacy in wildlife conservation will continue to inspire and guide all who were fortunate enough to know him and work with him.
