The most comprehensive scientific study of tiger habitats ever done finds that the big cats reside in 40 percent less habitat than they were thought to a decade ago. The tigers now occupy only 7 percent of their historic range.
This landmark study, commissioned by the National Fish & Wildlife Foundation's Save The Tiger Fund and produced by some of the world's leading tiger scientists at World Wildlife Fund, Wildlife Conservation Society, the Smithsonian's National Zoological Park and Save The Tiger Fund, calls for specific international actions to safeguard remaining populations. The study finds that conservation efforts such as protection from poaching, preservation of prey species, and preservation of tigers' natural habitat have resulted in some populations remaining stable and even increasing. But it concludes that long-term success is only achieved where there is a broad landscape-level conservation vision with buy-in from stakeholders.
"This report documents a low-water mark for tigers, and charts a way forward to reverse the tide," said John Robinson of the Wildlife Conservation Society. "We can save tigers forever. However, tiger conservation requires commitment from local partners, governments and international donors, along with effective, science-based conservation efforts to bring the species back to all parts of its biological range."
Synthesizing land use information, maps of human influence, and on-the-ground evidence of tigers, this study identifies 76 "tiger conservation landscapes" ??? places and habitats that have the best chance of supporting viable tiger populations into the future. Large carnivore populations like tigers are highly vulnerable to extinction in small and isolated reserves. Half the 76 landscapes can still support 100 tigers or more, providing excellent opportunities for recovery of wild tiger populations. The largest tiger landscapes exist in the Russian Far East and India. Southeast Asia also holds promise to sustain healthy tiger populations although many areas have lost tigers over the last 10 years.
"As tiger range spans borders, so must tiger conservation," said Eric Dinerstein, chief scientist and vice president of conservation science at World Wildlife Fund. "Asia's economic growth should not come at the expense of tiger habitat and the natural capital it protects."
The group's key conclusion from the study is that to safeguard remaining tigers, increased protection of the 20 highest priority tiger conservation landscapes is required. The group also stands ready to support the 13 countries with tigers in a regional effort to save the species. The report's authors suggest that the heads of state of those countries convene a "tiger summit" to elevate tiger conservation on their countries' agendas.
"Saving wild tigers requires tiger range countries to work together," said Mahendra Shrestha, director of National Fish and Wildlife Foundation's Save The Tiger Fund. "We have learned many important lessons over the last 10 years and this study provides a blueprint for scientists and the countries that hold the key for the tigers' survival."
The study was funded by the Save The Tiger Fund, a partnership between the ExxonMobil Foundation, the National Fish and Wildlife Foundation, and other donors such as the Critical Ecosystem Partnership Fund. Additional funding for this study was provided by the U.S. Fish and Wildlife Service and the U.N. Foundation. It was written by scientists from Wildlife Conservation Society, World Wildlife Fund and the Smithsonian's National Zoological Park.
