The Tamil Nadu Forest Department has announced that the tiger population estimation exercise will begin in the state from January 5, 2026, as part of the All India Tiger Estimation (AITE) — a nationwide survey conducted once every four years to assess the status of tigers, their co-predators, prey species, and habitats.According to an official department release, the first phase of this extensive exercise will span from January 5 to the end of February 2026. The initiative is coordinated by the National Tiger Conservation Authority (NTCA) in collaboration with the Wildlife Institute of India (WII) and state forest departments across the country.
The 2026 estimation will involve detailed habitat assessments using scientific methods such as sign surveys, line transects, camera trapping and genetic sampling. Modern monitoring tools like M-STRIPES and advanced technology will be employed to ensure accurate data collection.
The survey will cover all tiger reserves and tiger-bearing forest areas in Tamil Nadu, including both protected parks and private estates where tigers and co-predators are known to live. The state has also encouraged volunteers to participate by registering with the respective tiger reserve offices in advance.
Tamil Nadu currently has five tiger reserves — Kalakad Mundanthurai, Anamalai, Mudumalai, Sathyamangalam, and Srivilliputhur–Megamalai — which are key areas for the estimation work.
In previous estimations, the tiger population in Tamil Nadu increased from 264 in 2018 to 306 in 2022, reflecting steady growth in recent years. The final statewide report is expected to be released in 2027 after completion of all phases of the national survey.
This scientific exercise plays a crucial role in formulating conservation strategies and ensuring the protection of these endangered big cats and their natural habitats across the state and the country.
