India conducts first official survey of Ganges dolphins

The conservation of dolphins in India’s holiest, but most polluted waterway, is under the spotlight as the country conducts its first official count of the freshwater species. An estimated 450 volunteers, government experts and conservationists will take part in the exercise, which spans the states of Jharkhand, Uttar Pradesh, Bihar and West Bengal, in November and December.

“This is the first time a unified survey will be done for an aquatic animal. It has been done for elephants and tigers but this is more complicated,” Dr Sandeep Behera, consultant at the government’s National Mission for Clean Ganga, told The Sunday Times. “We are doing the survey in winter, when water levels drop and we can capture numbers in small isolated pockets and get a good idea of the population.”

The government also hopes to gauge the health of the river in the process. “This time we have taken aquatic biodiversity as an indicator of how pollution is affecting the Ganges,” said Dr Behera. The 2,500km-long river, which is considered holy by Hindus, who believe a dip in it cleanses sins, is heavily polluted with millions of tonnes of industrial effluent, sewage and pesticides. Cleaning it up has been a goal for decades and the Modi government has pledged more resources to tackle the pollution, including allocating more than 200bn rupees (S$4.3bn/£2bn) to the river.

Restoring its biodiversity, with the dolphin as the centrepiece, has also now become a part of the action plan for the Ganges. The dolphin unified count – meaning it is not just a piecemeal effort by individual conservationists – will provide baseline data that environmentalists say is crucial for saving the endangered species. Estimates put the number of the grey-brown mammals at between 1,500 and 3,600.

increasing pollution,” said Dr Sinha. Conservationists want India to avoid the fate of China, where the Yangtze river dolphin, which was last spotted in 2002, has been listed in some reports as extinct. There is only one other river dolphin species, in the Amazon, and a subspecies of the Ganges dolphin in the Indus river. “We want to know the exact number. It is very important for conservation efforts,” said Mr B A Khan, principal chief conservator of forests in the state of Bihar. “We will also be surveying the smaller tributaries, which has not been done before.”

Dr Behera said: “We hope the population has increased in pockets where they are getting support and food. But the target is to bring the endangered species back to the river system.”
