Pollution pushes Mekong dolphins on the brink of extinction

Washington, June 20 (ANI): A new report by the WWF (Worldwide fund for Nature) has revealed that pollution in the Mekong River has pushed the local population of Irrawaddy dolphins to the brink of extinction.

The Mekong dolphin population is estimated at between 66 and 86 individuals inhabiting a 190km stretch of the Mekong River between Cambodia and Lao PDR.

Since 2003, the population has suffered 88 deaths of which over 60 percent were calves under two weeks old. The latest population is estimated between 64 and 76 members.

“Necropsy analysis identified a bacterial disease as the cause of the calf deaths. This disease would not be fatal unless the dolphin’s immune systems were suppressed, as they were in these cases, by environmental contaminants,” said Dr Verne Dove, report author and veterinarian with WWF Cambodia.

Researchers found toxic levels of pesticides such as DDT and environmental contaminants such as PCBs during analysis of the dead dolphin calves.

These pollutants may also pose a health risk to human populations living along the Mekong that consume the same fish and water as the dolphins.

“These pollutants are widely distributed in the environment and so the source of this pollution may involve several countries through which the Mekong River flows. WWF Cambodia is currently investigating the source of the environmental contaminants,” said Dr Dove.

High levels of mercury were also found in some of the dead dolphins.

Mercury, suspected to be from gold mining activities, directly affects the immune system making the animals more susceptible to infectious disease.

“A trans-boundary preventative health programme is urgently needed to manage the disease affected animals in order to reduce the number of deaths each year,” said Seng Teak, Country Director of WWF Cambodia.

Limited genetic diversity due to inbreeding was another factor in the dolphin deaths.

“The Mekong River dolphins are isolated from other members of their species and they need our help. Science has shown that if the habitat of cetaceans is protected then populations can show remarkable resilience,” said Teak.

The Mekong River Irrawaddy dolphin has been listed as critically endangered on the IUCN Red List of Threatened Species since 2004. (ANI)

Elephants under threat as illegal ivory price soars in Vietnam

Washington, Feb 18 (ANI): A new market analysis released by TRAFFIC, the wildlife trade-monitoring network, has determined that the few surviving elephants in Indo-China are under increasing threat from booming illegal ivory prices in Vietnam.

An assessment of the illegal ivory trade in Viet Nam said Vietnamese illegal ivory prices could be the highest in the world, with reports of tusks selling for up to 1500 dollars per kg and small, cut pieces selling for up to 1863 dollars per kg.

Most of the raw ivory was said to originate from the Lao Peoples’ Democratic Republic, with small amounts from Viet Nam and Cambodia.

“This is a worrying trend that indicates even more pressure is being put on already fragile Asian Elephant populations,” said Azrina Abdullah, director of TRAFFIC Southeast Asia.

According to IUCN figures, no more than 1,000 elephants are believed to survive in Lao PDR, while in Vietnam, fewer than 150 are believed to exist.

In December 2008, TRAFFIC released a report that found evidence of widespread smuggling of live Asian Elephants and their ivory from Myanmar.

Mammoth ivory from Russia was also used in small quantities, but no African raw ivory was found, although it was still being illegally imported into Vietnam up to at least 2004.

Trade in ivory was outlawed in Viet Nam in 1992, but a major loophole in the legislation exists because shops can still sell ivory in stock dating from the prohibition.

This allows some shop owners to restock illegally with recently-made carved ivory.

In 2008, TRAFFIC surveyed 669 retail outlets across Viet Nam and found 73 (11 percent) selling a total of 2,444 ivory items.

Whilst the scale of the ivory market was smaller than in previous surveys, there were signs of increasing demand and overall numbers of craftsmen had increased since 2001.

“Although fewer ivory items were seen in 2008 than in 2001, worked ivory is increasingly being sold directly to buyers through middlemen or on the Internet, bypassing retail outlets,” said Abdullah. “Continued demand for illegal ivory is driving the prices so high,” she explained.

Recent seizures in and outside Viet Nam also suggest that most raw ivory is being supplied to China.

The main buyers of ivory were from China (including Hong Kong and Taiwan) and Thailand, local Vietnamese, American-Vietnamese and Europeans, in that order.

“This insidious illegal trade is further threatening the highly endangered elephants of Asia and must be stopped,” said Dr. Susan Lieberman, Director of the Species Programme for WWF-International. (ANI)
