Once Chitwan National Park in Nepal was the favourite hunting ground of poachers, but now it is they who are on the run and being hunted.
It is a rare successful conservation story in South Asia, where park officials and the Nepalese army have managed to turn the tide against poaching in the last few years.
Wild animals such as tigers, rhinos, elephants and leopards have been regularly killed by poachers for their body parts and skin, which fetch thousands of dollars on the black market.
The national park in the foothills of the Himalayas has succeeded particularly in protecting its most famous resident – the one-horned rhinoceros, also known as the Great Indian rhinoceros – from poachers.
Some conservationists believe it is one of the most endangered animals in the world – it features prominently on the red list of the International Union for Conservation of Nature (IUCN).
Around 20 or 25 elephants will take part in the exercise and we will scour an entire area with bushes or tall grass looking for poachers’ dens or hide outs”
About 10 years ago, when the country was deeply mired in a civil war between government forces and Maoist rebels, there was hardly any focus on wildlife protection in one of Nepal’s most famous parks.
The number of army monitoring posts in and around the park was reduced from 30 to seven as soldiers were shifted to anti-insurgency operations.
In 2002, about 37 rhinos were killed by poachers, triggering grave concern over the future of one-horned rhinos.
Their numbers dropped from an estimated 612 in 2000 to less than 375 in 2005.
“According to the last rhino census in 2011 the number of rhinos in the park has risen to more than 500,” said Kamal Jung Kunwar, a senior official at the Department of National Parks and Wildlife Conservation.
As the chief of the anti-poaching operation from 2003 to 2007, Mr Kunwar played a key role in the conservation of rhinos in Chitwan National Park.
Spread over an area of more than 930 sq km, the park consists mostly of Sal trees and grasslands. Its flat lowlands are home to a variety of endangered animals like Royal Bengal tigers, rhinos, leopards and Gharial crocodiles.
The successful conservation effort is attributed to a variety of initiatives, including tough action against poachers, enhanced intelligence and involving villagers living around the park in conservation efforts.
It has crucially involved the re-deployment of soldiers inside the park.
Park officials gave me rare access to the park’s anti-poaching teams whose trained elephant teams have performed so well in reducing rhino poaching over the last seven years.
In 2012, only one rhino was shot dead by poachers, while in 2011 no rhino was killed.
As part of their strategy, anti-poaching teams regularly use elephants to go deep inside the forest in search of poachers. The animals provide greater mobility in areas where there are few tracks or roads.
“Sometimes we bring elephants from other parks to hold a sweeping exercise. Around 20 or 25 elephants will take part in the exercise and we will scour an entire area with bushes or tall grass looking for poachers’ dens or hide outs,” Rupak Mahajan, co-ordinator of anti-poaching operations in the park told me.
The important role of the army in anti-poaching efforts can be seen by the various soldiers manning posts in different parts of the forest. They regularly do joint patrols with park officials.
Around 150 poachers and their collaborators have been convicted and jailed in the last few years. Sentences ranged from five to 15 years. The chief warden of the parks even has quasi-judicial powers.
“The tough punishments have acted as a deterrent,” Mr Kunwar said.
While the poaching of rhinos may have been reduced considerably, it has gone up dramatically at India’s Kaziranga National Park, home to the world’s largest concentration of one-horned rhinos. At least 17 have been killed by poachers there since the beginning of 2013.
