The Wildlife Institute of India (WII) recently released a survey on the Ganges river.
According to the survey, 49% of the river is high on biodiversity.
The study was conducted by the WII on behalf of National Mission for Clean Ganga undertaken by the Ministry of Jal Shakti.
10% of high biodiversity areas are Rajaji National Park in Uttarakhand, Vikramshila Gangetic Dolphin Sanctuary in Bihar, Hastinapur wildlife sanctuary.
The Gangetic Dolphins and Otters in the river have increased in numbers.
This indicates that the pollution level in the river has decreased and the river is in healthy state.
