“This is a pivotal step in the recovery of one of the world’s most endangered and iconic species,” Ginette Hemley, senior vice president of wildlife conservation at WWF, said in a statement. “Together with governments, local communities, philanthropists, and other NGOs, we’ve begun to reverse the trend in the century-long decline of tigers.”
The increase over the last six years reflects rising populations of tigers in several of 13 countries that pledged to double wild tiger numbers within 12 years following the 2010 Global Tiger Summit (the so-called Tx2 goal), Hemley told Scientific American. “The countries where we’re seeing high-level commitment—Russia, India, Nepal and Bhutan—are the ones where we’ve seen the biggest progress.”
The population estimates are subject to considerable error for some regions, such as in several countries—including Indonesia and Malaysia—that have not taken part in systematic surveys. And even in countries where population counts are more readily available, the surveys provide no information about the subspecies represented in each region, or the state of habitat fragmentation—a factor that could influence future population growth or decline.
Nonetheless, governments attending the meeting in New Delhi this week will be able to use the new estimates to inform conservation strategies aiming to boost this trend in tiger population numbers, Rajesh Gopal, secretary general of the Global Tiger Forum, told WWF. “This is a critical meeting taking place at the halfway point in the Tx2 goal,” he said. “Tiger governments will decide the next steps towards achieving this goal and ensuring wild tigers have a place in Asia’s future.”
