Rising tide: Why is the crocodile returning to the rivers of India like a crocodile? Environment

AThe sunlight is shining through the fog, a fisherman on a boat floating on the shores of the Gandak River in the Indian spring, offering a fine silk on a sandbar in the middle of the river. Most people make the same mistake as the crocodile, but it is given a certain fading bulb with a mass and a long jaw, it is said to be domestic.

Household (Guillaume Gangtax) Mistakes are often made for crocodiles or foxes. They are only in species گیوالیڈی Family: River dwellers who eat only fish and some crustaceans, and who were separated from all other crocodiles probably 65 million years ago.

There was a time when gharials were commonly found in the river ecosystem in the Indo-Pakistan subcontinent – Pakistan, Myanmar, Bangladesh and Bhutan. But the population is estimated to have shrunk from 10,000 in 1946 to less than 250 in 2006. 96 ٪ 9698 – A drop Within three generations, to please them There is a critical threat Category in the International Union for Conservation of Nature’s Red List.

But today, thanks to concrete conservation efforts, there is a glimmer of hope for the household, which is now found mainly in India and Nepal.

These efforts began in the 1970s, when the Indian government launched a Crocodile rearing and management plan In collaboration with the United Nations Development Program and the Food and Agriculture Organization. The National Chamber Sanctuary was established in 1978 and the following year the families of the first captives were released into the Chambal River, which flows through rivers and mountains in three states of Uttar Pradesh, Madhya Pradesh and Rajasthan. By 1992, the crocodile population had grown to 1,095.

Despite the setbacks – in the winter of 2007, more than 100 poor people were found dead due to gout due to toxins in the water – still near the Chambal River today. Gharial’s largest populationAccording to government estimates, about 1,800.

The success of the Chashmal project is now being replicated in Bihar. In 2010, after observing 15 male and female households on the Indian side of the Gandak River – which flows from Nepal to India, the Bihar government launched an initiative. Gandak Gharal Recovery Plan. The rest of the crocodiles in the river were captives born and raised to bolster the population. Issued in Gandak From 2014 to 2015, under a joint venture between the Department of Environment and Forests of India and the WTI.

Sulfur is an excellent habitat for the poor for its sandy branches and wet areas, which are better breeding grounds for the way they feed on these fish. BC Chaudhry, a trusted professor at WTI, said, “An interesting part of the exercise was raising about 30 young and sub-adult zoos from the Patna Zoo to the Gandak River around nine generations.” “Along with the release, a satellite transmitter was launched with some of the survivors to find their journey.”

Since 2016, nests have been set up every year with the help of local fishermen and farmers. The nests were saved from sand erosion and predators, and local nest watchers were deployed. “Members of the fishing community were trained to observe families and track their nesting behavior,” said Sameer Kumar Sinha, head of conservation at WTI.

When the male gharials reach sexual maturity, aged 10 or older, they develop bulbs on the tip of their vagina that resemble vessels. That’s it گھاڑا – A kind of Hindi word for pottery – This household got its name. The females lay their eggs on sand dunes and pot-shaped cliffs on the shores of river islands, where they protect themselves from predators. If danger appears, fathers can enter the bill to protect the family group. After about 70 days of incubation, the eggs enter the larvae on foot.

Several factors have played a role in reducing the crocodile population. Many people get caught in fishing nets or are caught by turtle hunters. They are also used in traditional medicine as their skin and trophies. Illegal sand mining along the river destroys the homes and nests of the poor, forcing them to abandon their preferred Basque sites. Basketing is essential for thoracic regulation in species.

One of the biggest dangers is the reckless use of dams and crumbling gates, which, after opening up the streams, are dragged away by the river, and the poor wash their eggs.

In 2018, the State Wildlife Board accepted the WTI’s recommendation to declare 140 km (87 miles) of the Gandak River as a conservation reserve, according to Bihar Chief Wildlife Warden PK Gupta. “This not only helps in the recovery of the Gharia population in this part of the river, but also in the ecosystem of other rivers,” he said.

“In March, we conducted a survey and the number of households rose to 260. Now it will increase,” Sinha said. In june 86 The new hatch poor After successful incubation of 65-70 days in the nests by members of the local community, it was released into the river.

“The wild snails in the Gandak River in Bihar make up about 7% to 8% of the global adult population, and we are proud to have been instrumental in doing so,” says Chaudhry. Gandak will probably become the country’s second most important wildlife breeding ground after the Chambal River.

Despite being about 16 feet (4.9 m) tall and some heavy reptiles on the ground – in some cases weighing up to 680 kg (1,500lb) – domesticated are generally shy, and hidden from humans, so it is always Finding is not easy.

But more is being discovered in India and other parts of Nepal. In 2019, two families were spotted on the Kosi River in Bihar – for the first time in almost 50 years. That same year, scientists at the London Zoological Society found the baby’s home in a remote area of ​​Nepal after nearly 30 years of absence, and this year the giraffes were found in the Yamuna River.

Households are still critically endangered, but as protection efforts continue, it is hoped that their numbers will continue to grow.
