Kali-Karnali jungle corridor proposed

When researchers installed camera traps deep in the forested mountains of western Nepal last year, they expected to capture lots of shots of leopards. And they did, but one day in April while scanning the images, they could not believe their eyes.

Among other animals that had taken selfies through the motion detector cameras, they found one of a tiger.

Never before had a Royal Bengal Tiger been sighted so high in the mountains of Nepal. Tigers are supposed to roam the tropical forests of the Bardia or Chitwan National Parks to the south, but this one was at 2,500m.

The Divisional Forestry Office in Dadeldhura had installed the cameras with support from World Wildlife Fund (WWF) Nepal after locals reported seeing tigers. The researchers wanted to make sure, because the Nepali word bagh can mean both tiger and leopard. Indeed, the cameras shot many pictures of leopards, and this one tiger.

“This convinced us that the forests of the Mahabharat Range here are not just a refuge for local wildlife, but is also an important nature corridor that should be protected,” said Ganesh Bhatta of the Dadeldhura District Coordination Committee. “We have got approval of the rural municipalities and will now take a proposal for a conservation area or national park to the Sudur Paschim Province assembly.”

The forests of the Province have regenerated in the past 35 years after the establishment of community forests, and the thick vegetation has led to a proliferation of native animal, bird and land species.

But it was the tiger sighting that made the case for a nature conservation zone stronger. Although this was the highest elevation at which a tiger has been seen in Nepal, the record is held by Bhutan’s Thrumsinghla National Park where tigers have been spotted at up to 3,350m.

Tiger ecologists say the spread of community forestry in Nepal, which has doubled the country’s woodland areas in the past 25 years could be one reason tigers are venturing so high. Other factors could be a reduction of prey density in the Tarai, water scarcity, as well as elevated temperatures in the plains due to global warming.

“The forests in the Mahabharat Range join the Kali and Karnali basins, and spread over an area of 700sq km that is important from a biodiversity perspective,” says Bishnu Acharya of the Dadeldhura Divisional Forestry Office, who adds that a further 800sq km could be declared a buffer zone, as in other conservation areas in the country.

If approved, the 1,500sq km conservation area would add to Nepal’s 27,300sq km of protected areas, of which 11,900sq km are national parks. For comparison, Chitwan National Park is only 950sq km.

Besides the tiger, the Divisional Forestry Office’s camera traps also showed the Mahabharat forests are teeming with other wildlife found both in the plains, such as the sambar deer and leopard, as well as ghoral and red fox which prefer the high Himalayan habitat.

“Most wildlife research in Nepal tends to be either in the Tarai or the high Himalaya, and the Mahabharat Range with an elevation between 3,000-4,000m is usually left out, which is all the more reason to study and protect the biodiversity here,” Acharya explained.

The camera traps were placed along the wildlife migratory route in the Bhageswar and Ghanteswar corridor with 32 camera in the first phase and 30 in the second. While most of the images in the first phase were of leopards, it was only later in the season that other animals, as well as the tiger, started appearing.

The slopes of the Mahabharat Range form Nepal’s mid-hill spine from east to west, and is the most-densely populated mountain region in the world. Deforestation had driven out most of the wildlife from here, but with community forestry, the vegetation and animals are staging a comeback. In addition, most mid-hill districts have seen a decline in human population because of out-migration, and a reduced birth rate.

Law makers both in Sudur Paschim Province as well as the Federal Parliament in Kathmandu are studying the National Parks and Wildlife Act of 1973 and the Forestry Act of 2019 to see if it is more feasible to declare the region a national park, or a conservation area.

Acharya says: “Either way, it is important to protect this forest. But which model is more appropriate is a political decision, and that has to be made at the provincial and central level.”

Meanwhile, conservationists have been trying to figure out where the tiger that they camera trapped in April came from: whether it had strayed across the border from Nandu National Park in India, or climbed up from the Shukla Phanta reserve in Nepal. They tried to compare the stripes to other tigers seen in Dadeldhura’s Jogbuda as well as Sukla Phanta, but none of them matched.

The Dadeldhura district authorities at first did not want to publicise the fact that a tiger had been sighted in the mountains, so as not to attract poachers during the Covid-19 lockdown. But they later decided to let the story out, and when they did many local villagers came up with reports of their own sightings.

One of them is 53-year-old Radha Devi Kathayat who lives near Dadeldhura town. She said: “It must have been about 22 years ago, we had gone to collect fodder in the forest and saw a tiger sprawled out in a clearing, fast asleep. It was definitely not a leopard with spots, this one had black stripes.” Her neighbour, Kalawati Kathayat, 54, confirmed she has also seen tigers in the forests before.

Zoologist Karan Shah at Tribhuvan University says it is not unusual that tigers are found at higher altitudes, it is just that no one was looking for them before and there is anecdotal evidence that tigers have actually been spotted even higher up to 3,500m in Nepal.

Acharya at the Dadeldhura Divisional Forestry Office says that if the proposal to set up a conservation area is indeed approved, the 53,014 hectares of Mahabharat forests in Dadeldhura and 23,000 hectares in Doti combined would form an important conservation corridor.
