A new peer-reviewed paper by the Wildlife Conservation Society and other groups reveals an ominous finding: most of the world's last remaining tigers—long decimated by overhunting, logging, and wildlife trade—are now clustered in just six percent of their available habitat. The paper identifies 42 'source sites' scattered across Asia that are now the last hope and greatest priority for the conservation and recovery of the world's largest cat.
The securing of the tiger's remaining source sites is the most effective and efficient way of not only preventing extinction but seeding a recovery of the wild tiger, the study's authors say. The researchers also assert that effective conservation efforts focused on these sites are both possible and economically feasible, requiring an additional $35 million a year for increased monitoring and enforcement to enable tiger numbers to double in these last strongholds.
The study—published online by PLoS Biology—is authored by: Wildlife Conservation Society researchers Joe Walston, John Robinson, Elizabeth Bennett, John Goodrich, Melvin Gumal, Arlyne Johnson, Ullas Karanth, Dale Miquelle, Anak Pattanavibool, Colin Poole, Emma Stokes, Chanthavy Vongkhamheng, and Hariyo Wibisono; Urs Breitenmoser of the IUCN/SSC Cat Specialist Group; Gustavo Fonseca of the Global Environment Facility (GEF); Luke Hunter and Alan Rabinowitz of Panthera; Nigel Leader-Williams of the University of Cambridge; Kathy MacKinnon of the World Bank; Dave Smith of the University of Minnesota; and Simon Stuart, Chair of the IUCN's Species Survival Commission
"While the scale of the challenge is enormous, the complexity of effective implementation is not," said Joe Walston, Director of the Wildlife Conservation Society's Asia Program and lead author of the study. "In the past, overly ambitious and complicated conservation efforts have failed to do the basics: prevent the hunting of tigers and their prey. With 70 percent of the world's wild tigers in just six percent of their current range, efforts need to focus on securing these sites as the number one priority for the species."
According to the paper, fewer than 3,500 tigers remain in the wild, of which only about 1,000 are breeding females. Walston and his co-authors identified 42 tiger source sites, which were defined as sites that contain breeding populations of tigers and have the potential to seed the recovery of tigers across wider landscapes.
India was identified as the most important country for the species with 18 source sites. Sumatra contains eight source sites, and the Russian Far East contains six.
The authors calculate the total required annual cost of effectively managing source sites to be $82 million, which includes the cost of law enforcement, wildlife monitoring, community involvement, and other factors. However, much of that is already being provided by range state governments themselves, supplemented by international support. The shortfall—$35 million—is needed to intensify proven methods of protection and monitoring on the ground.
"The tiger is facing its last stand as a species," said Dr. John Robinson, Executive Vice President of Conservation and Science for the Wildlife Conservation Society. "As dire as the situation is for tigers, the Wildlife Conservation Society is confident that the world community will come together to save these iconic big cats from the brink for future generations. This study gives us a roadmap to make that happen."
Dr. Gustavo Fonseca, team leader of natural resources at the Global Environment Facility, said: "A key goal for us is to help identify the most efficient path forward so countries can achieve their global biodiversity conservation objectives. The GEF is pleased to have been able to contribute to this initial assessment focusing on the highest priority sites for the future of this magnificent species"
Alan Rabinowitz, President and CEO of Panthera, said: "We know how to save tigers. We have the knowledge and the tools to get the job done. What we are lacking is political will and financial support. The price tag to save one of the planet's great iconic species is not a high one."
The authors say that in spite of decades of effort by conservationists, tigers continue to be threatened by overhunting of both tigers and their prey, and by loss and fragmentation of habitat. Much of the decline is being driven by the demand for tiger body parts used in traditional medicines.
The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. Visit www.wcs.org.

Our brain is a complex network with innumerable connections between cells. Neuronal cells have long thin extensions, so-called axons, which are branched to increase the number of interactions. Researchers at the Max Planck Institute of Biochemistry (MPIB) have collaborated with researchers from Portugal and France to study cellular branching processes. They demonstrated a novel mechanism that induces branching of microtubules, an intracellular support system. The newly discovered dynamics of microtubules has a key role in neuronal development. The results were recently published in the journal Nature Cell Biology.
From the twigs of trees to railroad switches – our environment teems with rigid branched objects. These objects are so omnipresent in our lives, we barely...
The Fraunhofer FEP has been involved in developing processes and equipment for cleaning, sterilization, and surface modification for decades. The CleanHand Network for development of systems and technologies to clean surfaces, materials, and objects was established in May 2018 to bundle the expertise of many partnering organizations. As a partner in the CleanHand Network, Fraunhofer FEP will present the Network and current research topics of the Institute in the field of hygiene and cleaning at the parts2clean trade fair, October 23-25, 2018 in Stuttgart, at the booth of the Fraunhofer Cleaning Technology Alliance (Hall 5, Booth C31).
Test reports and studies on the cleanliness of European motorway rest areas, hotel beds, and outdoor pools increasingly appear in the press, especially during...
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
