Eight years ago, some conservationists feared the worst for the world's wild tiger populations. Three of eight tiger subspecies had already gone extinct. Rampant poaching and habitat destruction appeared poised to consume the rest.
But this week a panel of wildlife biologists and conservation advocates sounded a more positive note.
"World populations of tigers have stabilized," said John Robinson, director of international conservation programs for The Wildlife Conservation Society, a nonprofit conservation organization based at the Bronx Zoo in New York. He was speaking Thursday at a press conference organized by the Save the Tiger Fund, a consortium of private environmental groups and U.S. government wildlife management agencies formed in 1995 to protect wild tiger populations. To date, the fund has spent U.S. $10 million dollars on tiger research and conservation, funding 196 programs in 13 countries.
"I think tigers are better off where we've invested time and money wisely," said Steven Galster, a specialist in conservation law enforcement now working in Southeast Asia for WildAid, a nonprofit environmental and human rights organization based in San Francisco.
Today there are between 5,000 to 7,500 tigers in the wild, according to estimates by the World Conservation Union. That figure represents a fraction of the 100,000 tigers found in the wild at the beginning of the 20th century, according to the Save the Tiger Fund. Of the five tiger subspecies that remainthe Amur or Siberian, Bengal, Indochinese, South China, and Sumatranall are endangered throughout their range. Poaching and habitat loss continue to pose the greatest threats to wild tiger populations today.
Compared to a decade ago, today there is more science available to the conservation community to better understand tiger habitat needs, panelists said.
K. Ullas Karanth, a conservation zoologist with the Wildlife Conservation Society working to conserve Bengal tiger populations in his native India, said that new research is having a profound impact on tiger management today.
"A female tigress raising cubs in some of the productive areas we work in requires about 15 square kilometers [6 square miles] of space. In the Russian Far East, the same tigress requires about 500 square kilometers [190 square miles]," said Karanth. "If you don't have this key piece of information gathered accurately, measured accurately, the conservation plans that you draw will not succeed."
The Poaching Crisis
In the early 1990s, there was wide evidence to suggest that poachers were killing tigers at a rapid pace. Most were hunted to supply the demand for tiger parts used in traditional Chinese medicine, according to Ginette Hemley, a vice president with the World Wildlife Fund, a nonprofit wildlife conservation organization based in Washington, D.C.
Tiger whiskers, eyes, brains, tails, and bones, in particular, are used in traditional remedies believed to cure ailments ranging from toothache to epilepsy. They are sold in markets in China, greater Asia, and the United States, which is home to large numbers of Asian immigrants and is the second largest market for tiger-based traditional Chinese medicinal products outside of China.
