Known for his articulate style, Thapar was not tethered to institutions, yet became a revered figure in conservation circles. As Ravi Singh of the World Wildlife Fund-India noted, his extensive knowledge and communication skills turned him into a powerful voice for tigers. Thapar’s efforts contributed significantly to the recovery of the tiger population in India, which had dwindled drastically from around 40,000 in the 1950s to just 1,411 by 2006. His work, alongside collective conservation endeavors, saw the population steadily rise to 3,682 by 2022. In the Ranthambhore Tiger Reserve, where his passion for tigers ignited, numbers increased from approximately 15 to about 70 during this span.

Thapar’s contributions to wildlife preservation and education have left an indelible mark on conservationist initiatives across the country. His influence and dedication will be remembered and honored within the communities he served.
