Overview The All India Tiger Estimation 2025-26 has commenced its field-level data collection in the Kannur Forest Division . This initiative involves systematic data gathering across tiger habitats to estimate the tiger population and assess ecological status. The first phase of the estimation began on December 1, 2025 , with staff already covering nearly 210 km on foot. Key Developments First Phase: Began on December 1, 2025 , focusing on systematic data gathering. Area Coverage: The Kannavam , Taliparamba , and Kottiyoor ranges are divided into blocks for efficient data collection. Team Involvement: Over 56 people are involved across 14 blocks , each supervised by a charge officer. Technology Use: Data is uploaded using the National Tiger Conservation Authority (NTCA) mobile application. Data Collection Method: Teams walk three trails of at least 5 km each and a transect line of at least 2 km within every block. Ecological Assessment: Observations are recorded through the ecological module of the M-STrIPES app, with photographic evidence. Protocol Adherence: The first phase adheres to an eight-day protocol designed for sign surveys and ecological assessment. Sanctuary Inclusion: Data is also being collected in the Aralam and Kottiyoor wildlife sanctuaries. Timeline: The first phase concludes on December 8, 2025 , followed by the installation of camera traps. UPSC Relevance This news is relevant to GS3: Environment and Ecology , specifically concerning biodiversity conservation and wildlife management. The All India Tiger Estimation is a crucial exercise for understanding tiger populations and implementing effective conservation strategies. The use of technology like the M-STrIPES app highlights the role of innovation in environmental monitoring. Important Facts The All India Tiger Estimation is conducted periodically to assess the tiger population across the country. The NTCA is the primary body responsible for tiger conservation in India. M-STrIPES (Monitoring System for Tigers - Intensive Protection and Ecological Status) is a software used for tiger reserve monitoring. The data collected will be compiled at the division level and forwarded to the NTCA . The exercise involves both sign surveys and ecological assessments to provide a comprehensive understanding of tiger habitats. Key Terms NTCA: National Tiger Conservation Authority, a statutory body under the Ministry of Environment, Forest and Climate Change. M-STrIPES: Monitoring System for Tigers - Intensive Protection and Ecological Status, a software for tiger reserve monitoring. Transect Line: A straight line along which ecological data is recorded. Sign Survey: A method of wildlife monitoring involving the identification and recording of animal signs.
