India Tiger Population Hits 3,682 but Reserves Reach Carrying Capacity

India now has an estimated 3,682 tigers across five major landscapes, up from around 1,400 in the early 2000s, but wildlife biologist Qamar Qureshi warned at the Anil Agarwal Dialogue 2026 that many reserves are now operating at full carrying capacity and pushing numbers higher without habitat restoration will intensify human-wildlife conflict. The next phase of conservation must shift from reserve-centric protection to landscape-scale governance.

Qureshi explained that sustaining a single tiger requires roughly 349 ungulates annually based on established predator-prey equations, and where prey densities are low, carnivore populations cannot persist. While Corbett, Kaziranga, the Western Ghats complex and parts of central India function as strong source populations, habitat recovery requiring removal of invasives, grassland restoration, water management and prey augmentation takes over a decade of sustained effort, as demonstrated at Kuno. Corridor fragmentation from linear infrastructure and mining in central India — the only region with room for significant future expansion — remains a critical constraint.

India's elephant population, estimated at 22,446 with the largest numbers in the Western Ghats, faces rising conflict as fragmented corridors and habitat degradation alter movement routes. The Gangetic river dolphin population is estimated at 6,327, but heavy water extraction, barrages and expanding inland navigation disrupt the species' sonar-based communication. The Great Indian Bustard may number only 100-150 individuals, with high mortality along transmission corridors identified as a major threat. Grassland species, wolves, lions, hangul and khur face shared challenges of fragmentation, declining forest quality, and shrinking social tolerance.

Qureshi argued that protected areas are becoming ecological islands and that there is no solution for human-wildlife conflict under the current trajectory. He called for landscape-scale governance that integrates prey recovery, corridor security and ecological planning into development decisions from the outset. Tigers disperse hundreds of kilometres instinctively to avoid inbreeding, making corridors ecological necessities rather than optional additions. Qureshi said although tiger corridors now have some legal backing, consistent enforcement and integration with infrastructure planning are needed to sustain India's conservation gains.
