Dolphin numbers rise in Saptakoshi River, boosting conservation hopes

The dolphin population in the Saptakoshi River, within the Koshi Wildlife Reserve, has risen this year, according to a four-day census conducted from June 1 to 4, with results announced on World Environment Day.

This year’s count revealed 22 dolphins—15 adults, five semi-adults, and two calves—marking an increase of three compared to last year, a promising sign for conservation efforts.

The river hosts the rare Gangetic dolphin, a highly intelligent marine mammal that thrives in clean, deep waters.

In 2012, the dolphin count stood at 11, rising to 17 by 2017, spurring the Reserve to bolster conservation initiatives.

The 2024 census recorded 19 dolphins in Nepal’s largest river, and this year’s uptick highlights progress in protecting this precious species.
