SUNSARI, June 6: The Koshi Tappu Wildlife Reserve has reported an increase in the number of dolphins in the Saptakoshi River. On the occasion of World Environment Day, the Reserve unveiled the findings of a four-day dolphin count conducted recently. Compared to last year, the survey recorded three more dolphins in the area.
According to Bhupendra Prasad Yadav, Senior Conservation Officer at the Reserve, a total of 22 dolphins were recorded this year, including 15 adults, five sub-adults, and two calves. “This figure is a positive sign for the Saptakoshi River and indicates a shift toward improvement. We must work to conserve and promote this change,” Yadav said.
The Koshi Tappu Wildlife Reserve conducts annual dolphin counts as part of its regular conservation efforts. The Ganges river dolphin, a rare species, is found in the river. “Dolphins prefer clean and deep waters, which also reflects the improved health and quality of the river ecosystem,” added Yadav.
The survey received technical support from the National Nature Conservation Trust, Koshi Conservation Center, Shri Bhimkali Battalion, and the Himalayan Nature organization. In 2012, 11 dolphins were recorded, and in 2017, the number had increased to 17. Since then, the Reserve has prioritized dolphin conservation, initiating annual monitoring as part of its strategy.
The Reserve recorded 17 dolphins in 2022, and 19 each in 2023 and 2024. It continues to emphasize the protection of dolphins and their natural habitat as part of its long-term conservation mission.
