The number of tigers and cubs in the Sundarbans has increased. Compared to the 2018 survey, the latest 2024 survey shows that the tiger population has grown by 11, as reported by Syeda Rizwana Hasan, Advisor to the Ministry of Environment, Forest and Climate Change. She revealed this information at a press conference held on Tuesday (October 8) at the Secretariat, during the announcement of the results of the "Sundarbans Tiger Survey 2024."
According to the 2018 survey, the Sundarbans had 114 tigers. The latest survey has found 125 tigers, marking an increase of 11. Rizwana Hasan stated that, based on overall analysis, the 2023-2024 Sundarbans tiger survey recorded 125 tigers, with a density of 2.64 tigers per 100 square kilometers.
She further noted that the first tiger survey in the Sundarbans using modern camera trapping methods was conducted in 2015, which identified 106 tigers. At that time, the density was 2.17 tigers per 100 square kilometers. In the second phase of camera trapping in 2018, 114 tigers were found, with a density of 2.55 per 100 square kilometers. The advisor stated that the third phase of the tiger survey, carried out entirely with government funding under the Sundarbans Tiger Conservation Project, began in January 2023 and was completed in March 2024.
For this survey, camera traps were installed in four blocks—Satkhira, Khulna, Chandpai, and Sharankhola ranges of the Sundarbans—covering 605 grid locations. A total of 1,210 automatic cameras were deployed across these grids for 318 days. Tigers were captured on camera in 368 of those grid locations. From over one million photos and videos taken, 7,297 tiger images were identified. Experts analyzed the unique stripe patterns and body parts to identify individual tigers.
The advisor added that a significant number of tiger cubs were also photographed in the 2023–24 survey. However, cubs are not included in the final count, due to the high mortality rate before reaching adulthood.
This time, 21 tiger cubs were captured in photographs. In contrast, only five cubs were photographed in each of the 2015 and 2018 surveys. At the press conference, Professor M. A. Aziz from the Department of Zoology at Jahangirnagar University mentioned that the Sundarbans continues to provide a favorable environment for tiger reproduction, and the tiger population may continue to grow in the future.
