Dung may be key to tracking elusive tigers

PHNOM PENH: A dog trained to sniff for tiger droppings will help conservationists determine if the big cats still roam one of Cambodia’s largest nature reserves.

Starting next week, Maggie, a German wirehaired pointer, will begin scouring the undergrowth and sniffing for tiger scent on trees at the 3,000-sq-km Seima Biodiversity Conservation Area in northeastern Cambodia.

The unorthodox move to employ a dog trained in Russia to search for signs of tigers comes after camera traps and field surveys failed to find the big cats last year. The last sign of a tiger was in 2007, when a paw print was spotted in the park.

‘Best method’

“We think this is the best method when we have a large area and not that many tigers,” said Hannah O’Kelly, a wildlife monitoring adviser for the New York-based Wildlife Conservation Society, which along with the wild cat conservation group Panthera is spending about $30,000 to bring Maggie and a second dog from Russia to Seima later this year.

Hiring the two dogs is part of a $10 million, 10-year initiative by WCS and Panthera, also based in New York, called ‘Tigers Forever.’ It aims to increase the numbers of tigers by 50 per cent in Cambodia, China, India, Indonesia, Laos, Myanmar, the Russian Far East and Thailand through a range of measures that include better monitoring, assessments of threats and efforts to minimise the dangers facing the big cats.

The campaign was launched in 2006 to combat a dwindling tiger population in Asia. Across the continent, the number of tigers has plummeted to as few as 5,000 tigers from a high of 100,000 a century ago due to poaching, habitat loss and other threats. It is unclear how many tigers remain in Cambodia.

Men Soriyun, a project manager for Seima Biodiversity Conservation Area, said dogs offered the best hope of finding the tigers and that the method could be used by other national reserves. Cambodia is the first country in Asia to employ the dogs to search for tigers, a method pioneered in Russia’s Far East region which has hundreds of tigers spread across several thousand kilometres. Since then, dogs have been used to search for jaguars in South America and leopards in Africa.

All six dogs taught to search for tigers were trained by wildlife biologist and WCS consultant Linda Kerley in Russia’s Lazovsky Nature Reserve. The best dogs for the task, she said, are hunting or sheep herding dogs that can easily detect the musky smell of the tiger’s scat, excrement left by a wild animal.

“We don’t want a dog that will hunt tigers,” said Ms. Kerley, who accompanied Maggie to Cambodia. “We want a dog that wants to hunt for the scent of the scat.”

Genetic information
