Study: To save tigers, protect key breeding areas

A closer look JAKARTA, Indonesia Conservationists must protect tiger populations in a few concentrated breeding grounds in Asia instead of trying to safeguard vast, surrounding landscapes if they want to save the big cats from extinction, scientists said.
Only about 3,500 tigers are left in the wild worldwide, fewer than one third of them breeding females, according to one of the study's authors, John Robinson of the Wildlife Conservation Society.
Much has been done to try to save the world's largest cat -- threatened by over-hunting, habitat loss and the wildlife trade -- but the numbers have continued to spiral downward for two decades.
That's in part because conservation efforts are increasingly diverse and often aimed at improving habitats outside protected areas, according to the study, published in a recent PLoS Biology journal. Instead, efforts should focus on the areas where tigers live -- most are clustered in just 6 percent of their available habitat -- and especially where they breed.
"The immediate priority must be to ensure that the last remaining breeding populations are protected and continually monitored," the study says. Otherwise, "all other efforts are bound to fail."
Conservation groups say the world's tiger population has fallen from about 5,000 in 1998 to as few as 3,200 today, despite tens of millions of dollars invested in conservation efforts.
The study identifies 42 key areas of potential. Eighteen are in India -- the country with the most tigers -- eight in Indonesia, six in Russia's Far East and the others scattered elsewhere in Asia.
The price tag for the plan, which would require greater levels of law enforcement and surveillance, would be about $82 million a year, the study says.
