Conservationists prepare for 2026 Tiger census

India is gearing up for its next all-India tiger census, a monumental exercise conducted every four years that serves as the backbone of the country's tiger conservation efforts. The 2022 census revealed a thriving population of 3,167 tigers, a testament to the success of decades of conservation programs under "Project Tiger." As authorities prepare for the 2026 count, they face the complex challenge of accurately numbering these elusive and wide-ranging predators.

Tigers are natural wanderers, traveling tens of kilometers daily in search of food and mates. This migratory behavior presents a significant logistical challenge, as a tiger's territory can easily span across multiple states. For example, tigers from the Amrabad Tiger Reserve in Telangana are known to swim across the Krishna River to enter Andhra Pradesh. Similarly, tigers from the forests of Asifabad district often cross into Maharashtra. This constant movement necessitates a meticulously coordinated, multi-state counting effort to avoid double-counting and to understand the interconnectedness of tiger populations.

To overcome these challenges, conservation authorities employ a suite of sophisticated scientific methods. These techniques have moved far beyond traditional counting methods to provide a precise and reliable population estimate.

• Stripe Pattern Identification: This is the most fundamental and accurate method. Every tiger's stripe pattern is as unique as a human fingerprint. Researchers use high-resolution cameras to capture images of tigers from both sides, and specialized software analyzes these unique patterns. This allows each individual to be identified and tracked, providing the most reliable data for the census.

• Camera Traps: This non-invasive technology is the workhorse of the census. Motion-activated cameras are strategically placed in grids across tiger habitats. They capture a trove of data, including photos and videos, which are then analyzed to identify and count individual tigers based on their unique stripes. The traps also provide invaluable information on tiger behavior, prey density, and habitat usage.

• DNA Profiling: For a more definitive identification, hair and scat (feces) samples are collected from the field. Genetic analysis of these samples can pinpoint a specific tiger, and even reveal its genetic lineage. This is a powerful tool for monitoring the genetic health of the population and understanding migration patterns.

• Radio Collaring: To gain detailed insights into individual tiger behavior, some of the larger tigers are fitted with radio collars. These collars provide real-time data on a tiger's movements, territory size, and interactions with other wildlife. This intensive monitoring data helps conservationists make informed decisions about managing tiger habitats and mitigating human-wildlife conflict.

The 2022 census highlighted the success of conservation efforts in many states. Madhya Pradesh continues to lead the nation's tiger population, followed closely by Karnataka.

The upcoming 2026 census will be crucial in measuring the continued success of India's conservation policies. The data gathered will guide future strategies and ensure the survival of this magnificent species.
