Study says 2000 tigers possible in Thailand

Dec 20 ,General Science


Thailand’s Western Forest Complex – a 6,900 square mile (18,000 square kilometers) network of parks and wildlife reserves – can potentially support some 2,000 tigers, making it one of the world’s strongholds for these emblematic big cats, according to a new study by Thailand’s Department of National Park, Wildlife, and Plant Conservation and the New York-based Wildlife Conservation Society.

The study, which appears in latest issue of the journal Oryx, says that to make these numbers a reality, better enforcement to safeguard both tigers and their prey from poachers is critical.

According to the study, the entire Western Forest Complex currently supports an estimated 720 tigers. These tiger densities were lower than those reported by Wildlife Conservation Society scientists from some protected areas in India with similar habitat, but better enforcement. For example, tiger densities of as many as 12 tigers per 100 square kilometers were measured in India’s Nagarahole, Bandipur and Kanha forests, as opposed to four tigers per 100 square kilometers in Thailand’s Huai Kha Khaeng Wildlife Sanctuary.

The authors of the study conducted intensive surveys of tigers in Huai Kha Khaeng, using camera traps to estimate a population size of 113 individual animals living in the 1,084 square-mile (2,810 square kilometer) protected area.

Despite the lower densities, plenty of good tiger habitat remains in Thailand, with 25 percent of the nation still forested, and 15 percent of it managed under wildlife protection legislation.

“Thailand has the potential to be a global centerpiece for tiger conservation,” said Dr. Anak Pattanavibool of the Wildlife Conservation Society’s Thailand Program and a coauthor of the study. “This study underscores that there is an opportunity for tigers to thrive in Thailand – provided tigers and their major prey species are protected from poachers.”

“Working together with WCS scientists helps set a standard for tiger monitoring and conservation here in Thailand,” said Saksit Simcharoen, a tiger specialist working for the Thai government. “The tiger and prey population monitoring and patrol improvement systems have given people hope and direction to do better for tigers and other wildlife.”

Other Co-authors of the study included scientists from the U.S. Geological Survey.

Though no truly accurate global numbers exist, conservationists roughly estimate that 5,000 tigers remain in the wild. 150 years ago, an estimated 100,000 tigers may have roamed throughout much of Asia.

Last year, the Panthera Foundation in collaboration with the Wildlife Conservation Society announced its “Tigers Forever” program that pledges a 50 percent increase in tiger numbers in key areas over the next decade.

Viable tiger populations, tiger trade incompatible
In the cover story of this month’s BioScience journal, leading tiger experts warn that if tigers are to survive, governments must stop all trade in tiger products from wild and captive-bred sources, as well as ramp up efforts to conserve the species and their habitats. The paper, “The Fate of Wild Tigers,” describes the wild tiger's population decline as "catastrophic" and urges international cooperation to ensure the animal's continued existence in the wild.
Threats to wild tigers growing
The animal's range is decreasing, but successful programs point to ways to protect the species
The wild tiger now occupies a mere 7 percent of its historic range, and the area known to be inhabited by tigers has declined by 41 percent over the past decade, according to an article published in the June 2007 issue of BioScience. Growing trade in folk medicines made from tiger parts and tiger skins, along with habitat loss and fragmentation, is believed to be the chief reason for the losses. The assessment, by Eric Dinerstein of the World Wildlife Fund and 15 coauthors, describes the wild tiger's population trajectory as "catastrophic" and urges international cooperation to ensure the animal's continued existence in the wild.

Despite the discouraging numbers--there are believed to be only about 5,000 wild tigers left--some conservation programs have been successful. Dinerstein and his coauthors highlight a program in the Terai-Arc Landscape of northwestern India and southern Nepal as a notable victory. The scheme features wildlife corridors that connect 12 reserves. Tiger conservation efforts have also been successful in the Russian Far East. Many tiger reserves in the India, in contrast, have been mismanaged and have failed to protect the animals, according to the article.

Plans to make use of tiger parts harvested from farmed tigers in China represent an emerging threat, the authors argue. Any trade in tiger parts encourages poaching, because products made from animals farmed at great expense cannot be distinguished from products made from wild tigers.

Because tigers must be able to roam over large areas, long-term conservation of the species will need planning that involves religious and civic leaders as well as national and local governments. International cooperation among nations that harbor the animal will also be essential. Dinerstein and his coauthors conclude by recommending that these countries appoint "tiger ambassadors" to advocate for the species, step up efforts to prosecute poachers, and provide economic incentives to encourage conservation.
