Cambodia remains last vulture bastion in Southeast Asia

26.06.2012
Wildlife Conservation Society and the Royal Government of Cambodia say that more vulture 'restaurants' and reduction of poison in hunting is critical to saving vultures in Asia

In face of what has become a precipitous slide toward extinction across the Asian continent, the vultures of Cambodia have persisted, giving conservationists hope that these important scavengers can come back from the brink, according to authors from the Wildlife Conservation Society, the Royal Government of Cambodia, and other groups in a new study.

The creation of new feeding stations, or vulture "restaurants," and the restoration of populations of depleted wildlife species represent the next important steps in vulture conservation, the study says.

The paper appears in the online edition of Bird Conservation International. Authors include: Tom Clements, Martin Gilbert, and Hugo J. Rainey of the Wildlife Conservation Society; Richard Cuthbert of the Royal Society for the Protection of Birds; Jonathan C. Eames of BirdLife International in Indochina; Pech Bunnat and Song Chansocheat of the Ministry of the Environment, Royal Government of Cambodia; Seng Teak of the World Wide Fund for Nature—Cambodia Program; and Tan Setha of the Ministry of Agriculture, Forestry, and Fisheries, Royal Government of Cambodia.

"Results from vulture censuses from the past several years have been encouraging, with new nests recorded and even population increases," said WCS researcher Tom Clements, lead author on the new paper. "With continued investment, these critical populations can survive and grow."

In the study, which began in 2004, the authors collected data from several sites in Cambodia, Lao PDR, and Vietnam through a variety of methods, including monitoring of vulture nesting sites and feeding stations; health assessments of vultures; interviews with government officials, hunters, and wildlife traders to collect data on threats; and satellite transmitter vests on four birds to assess ranging patterns.

The findings: while Cambodia's vulture populations remain robust, the use of poison by hunters and fishers for capturing other species are leading to unintended vulture mortalities. According to the data, 74 percent of the 42 recorded mortalities during the study period were attributable to poison. Direct persecution (the shooting of vultures with guns and slingshots) was also significant, accounting for 10 percent of recorded vulture mortality.

The extreme importance of Cambodia's vulture population was created by an ecological disaster across Asia due largely to the veterinary drug diclofenac. Widely used as an anti-inflammatory drug for cattle in South Asia, diclofenac is toxic to vultures, causing death through renal failure and visceral gout to birds that feed on the cattle carcasses. It has led to a global population declines higher than 99 percent in some vulture species.

So far, the drug has not impacted the vulture populations of Cambodia because diclofenac is not used. WCS and other partners have actually recorded increases in some species of vulture in these areas. However, vultures in Cambodia are largely dependent on domestic animals for food, as populations of wild species such as gaur and Eld's deer remain low.

"Fortunately, the Royal Government of Cambodia has instituted measures to ban diclofenac to ensure the survival of these important birds," said Joe Walston, Director of WCS's Asia Program. "The challenge now is to reduce the indirect and direct persecution of vultures, specifically from poisoning and shooting, and longer-term pressures from habitat loss."

The slender-billed vulture, white-rumped vulture, and red-headed vulture are all listed as "Critically Endangered" by the International Union for Conservation of Nature.

The Cambodia Vulture Conservation Project is a collaboration between the General Department of Administration for Nature Conservation and Protection (GDANCP) of the Ministry of Environment (MoE), the Forestry Administration (FA) of the Ministry of Agriculture, Forestry and Fisheries (MAFF), the Wildlife Conservation Society (WCS), BirdLife International in Indochina, World Wide Fund for Nature (WWF), the Angkor Centre for Conservation of Biodiversity (ACCB) and Wildlife Alliance. This work has been made possible through the generous support of the Royal Society for the Protection of Birds (RSPB), the Disney Worldwide Conservation Fund, the Global Environment Facility – United Nations Development Program, the Darwin Initiative and the Critical Ecosystem Partnership Fund. The Critical Ecosystem Partnership Fund is a joint initiative of l'Agence Française de Développement, Conservation International, the Global Environment Facility, the Government of Japan, the MacArthur Foundation and the World Bank.

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
