BANGKOK — More than a decade ago, it was common for elephant owners to take their animals into Thailand’s cities and beg in the streets. Other elephants were put to work by illegal loggers along the border with Myanmar to harvest timber and haul it out of the forest.

Gradually, Thailand succeeded in reducing such practices and improving the lives of domesticated elephants. But now, the coronavirus that is sickening humans around the world may threaten to undo that progress.

A sudden drop in foreign tourists has forced the closing of dozens of elephant parks and similar tourist attractions, putting more than 1,000 elephants in Thailand out of work and endangering their futures, operators of the attractions said.

In recent years, the main concern that animal welfare advocates have raised about Thailand’s many elephant attractions has been whether it is abusive for tourists to ride the creatures.

But for many owners, just keeping them fed is now a more urgent concern. Feeding an elephant can cost as much as US$40 a day — more than three times the minimum daily wage in Thailand.

Mr Theerapat Trungprakan, president of the Thai Elephant Alliance Association, a group of elephant attraction operators, said he feared that unless the government intervened, some elephants would be forced back onto the streets or even into illegal logging operations.

“We don’t want that loop of survival alternatives to come back,” Mr Theerapat said. “It will endanger the welfare of the elephants, such as having the elephants roaming the streets begging for bananas or sugar cane.”

Thailand has sought to stop the spread of the virus by closing schools and entertainment venues and by encouraging people to stay home.

The initial outbreak in China led to a sudden drop in visitors to Thailand, as both countries restricted travel. In 2019, China contributed more than a quarter of Thailand’s 40 million tourists.

In February, overall tourist arrivals in Thailand were down by 44 per cent compared with a year earlier. Tourism has plunged even further in March with new limits on travel and activity.

Tourism is a huge part of the Thai economy. Before the virus struck, travel and tourism accounted for more than 20 per cent of the country’s gross domestic product and employed nearly 16 per cent of the workforce.

The effects have been felt nationwide. Hotel rooms are vacant and taxis idle. Major events have been postponed or cancelled, including the Thai New Year festivals normally held in April as well as the first WBC Muay Thai World Convention, which had been scheduled for this month in Bangkok.

The elephant attractions have been hit hard, operators say.

In northern Thailand, 85 such businesses have temporarily halted operations because of a lack of visitors, said Mr Borpit Chailert, general manager of Maetaeng Elephant Park, north of the city of Chiang Mai.

He said the Maetaeng park, one of the country’s larger operations, was still open, but visitors were down by 90 per cent, forcing the company to reduce employees’ hours. The park used to get as many as 1,000 visitors a day. On Saturday, there were only four.

Thailand has about 3,800 domesticated elephants. Releasing them into the forest, where about 3,000 wild elephants live, is not an option because it is illegal under Thai law; in the forest, domesticated elephants would compete with wild counterparts.

“They cannot look for food in the forest because they are used to being fed,” Mr Borpit said. “Imagine if we released around 3,000 domesticated elephants into the forest at the same time. There would be no food to feed all the elephants.”

Elephants are Thailand’s national symbol. Some were used in logging operations for generations before 1989, when Thailand, facing the rapid destruction of its forests, banned nearly all commercial logging.

More recently, many captive elephants have been put to work in tourist attractions, often in small operations with a dozen or so animals, where visitors can ride them. Some larger venues also offer elephant rides.

Animal welfare advocates say the training and treatment of elephants in such operations are often abusive, and they call for an end to using the animals in circuses or letting tourists ride them. They say it is better for tourists simply to observe the animals in refuges and sanctuaries, which are a growing part of the business.

A group that promotes the welfare of elephants in Thailand, the Friends of the Asian Elephant Foundation, has long urged the government to establish a fund for this kind of tourism emergency.

“This funding is important because with no income, where will the elephant owners and park owners get the money to buy food for the elephants?” said the group’s co-founder and secretary-general, Ms Soraida Salwala. “I am very worried about this situation.”

Mr Theerapat, the Thai Elephant Alliance Association president, said most of the elephants in Thailand’s attractions were rented from their owners. If the parks return them, he said, some owners might decide they have no choice but to beg on the streets.

Or some elephants could be forced to haul timber along the borders with Myanmar and Laos, where they would risk stepping on land mines left from conflicts in the region, he said.

“These elephants have to live in a risky area,” Mr Theerapat said. “When they go back, in some areas there is still illegal logging. And when the elephant owner’s savings are depleted, he might think that is a way out.” THE NEW YORK TIMES
