Dudhwa releases four rhinos into free range, pushing wild population to eight

Four greater one-horned rhinos were moved out of Dudhwa Tiger Reserve's fenced rehabilitation area into suitable grassland habitat in March 2026, taking the number of mature rhinos free-ranging in Dudhwa to eight. The state's longer-term plan aims to explore the feasibility of having 10 rhinos free-ranging as an initial phase of a wider conservation strategy. The latest census, conducted in June 2026, counted 53 rhinos in Dudhwa: 17 adult males, 25 adult females and 11 calves older than one year. Eight of them were among those released from rehabilitation enclosures to improve genetic diversity and reduce inbreeding.

Dudhwa's rhino story began in 1984 when five rhinos were brought in as part of a reintroduction programme. The population has since grown, demonstrating the Terai can once again support the species. A 2022 analysis estimated around 20% of Dudhwa was under grasslands and another 3% under wetlands, marshes and swamps — habitat classes critical for a flourishing rhino population. Amit Sharma, National Lead for Rhino Conservation at WWF India, said: "It is a great achievement for rhino conservation in Dudhwa as the rhinos have been allowed free range outside the enclosed area after almost four decades. Even though the initial plans are to release 10 rhinos, the objective should be more than releasing the 10 rhinos — it should be establishing an ecologically functional, demographically viable and genetically resilient free-ranging rhino population."

Sharma stressed long-term monitoring for individual identification, reproductive success, calf survival, mortality, home-range use, forage availability and genetic diversity. A 2025 Wildlife Institute of India study on the Western Terai Arc Landscape highlighted how roads and development disrupt wildlife corridors. Rhinos move across the India-Nepal border regularly at Pilibhit, Katerniaghat and Valmiki. In March 2026, a 30-year-old female rhino named Rajeshwari was found dead in a water body with a tiger on her carcass; post-mortem confirmed death from injuries sustained in the attack.

Why it matters: Dudhwa tests whether a reintroduced population can become a self-sustaining, connected metapopulation across the wider Terai landscape.
