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, less
than one third of them breeding females, according to one of the authors of the
study, 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 their
numbers have continued to spiral downward for nearly 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 Tuesday's issue of the peer-reviewed PLoS Biology
journal.
Instead, efforts should be concentrated 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,"
it says, adding if that doesn't happen, "all other efforts are bound to
fail."
The WWF and other conservation groups say the world's tiger
population has fallen from around 5,000 in 1998 to as few as 3,200 today,
despite tens of millions of dollars invested in conservation efforts.
The cats have been lost largely to poachers, who cash in on
a huge market for tiger skins and a belief, prevalent in east Asia, that eating
or applying tiger parts enhance health and virility.
The new study - to which researchers from the
conservationist group Panthera, the World Bank, the University of Cambridge and
others also contributed - identifies 42 key areas that have concentrations of
tigers with the potential to grow and populate larger landscapes.
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 around $82 million a
year, the study says.
The bulk of that is already being provided by state
governments and international support.
Similar efforts have been successful in the past -
especially in India.
The Malenad-Mysore landscape in southern India has 220 adult
tigers, one of the largest populations in the world, thanks largely to
intensive protection of its "source site," the Nagarahole National
Park, in the 1970s.
Those high densities have now been maintained for 30 years,
the authors wrote, pointing to similar success stories with the African
rhinoceros.
Alan Rabinowitz, president of Panthera, said focusing on
breeding grounds is "absolutely necessary right now if we are to save
tigers in the wild."
But he stressed that in the long-term, it is important that
tigers be able to move in surrounding landscapes to maintain genetic and
demographic viability.
"Otherwise we are boxing ourselves into a corner that
would allow only for contained, managed populations."
Barney Long, of the WWF Species Program and independent of
the study, agreed, saying conservationists shouldn't create "living
zoos."
One of the criticisms about recent tiger conservation
efforts is that they extend well beyond protected areas, managing ecosystems
and working with local communities to help tiger and human populations coexist.
Debbie Martyr, who set up an anti-poaching unit on
Indonesia's island of Sumatra, said much can be achieved by protecting key
tiger habitats. She also was not tied to the study.
If the government is determined to help protect such areas
and crack down on poachers there could be a significant increase in tiger
numbers, she said.
"In fact, I'm going to stick my neck out a little here,
but I'd say in 10 years time, there could be more tigers on Sumatra (around 300
today) than in India (1,400)."
