However, given the precariousness of the Cat Tien population, demographic considerations may override genetic issues in the short term. The Ujung Kulon and Cat Tien populations represent separate Evolutionary Significant Units, advocating independent management. ![]() ![]() Divergence between Javan rhinos from Ujung Kulon and Cat Tien was similar to that between recognized subspecies of African rhinos, and exceeded that between Sumatran rhinos. ![]() As its critically endangered status precluded invasive sampling, we extracted DNA from dung, amplifying and sequencing segments of the mtDNA 12S rRNA gene and the non-coding D-loop. Here we report on the first genetic analysis of the two extant populations, in Ujung Kulon, Indonesia, and Cat Tien, Vietnam, and discuss their conservation. Although species specific information is crucial to its conservation, its precarious status, habitat inaccessibility, and behavioral adaptations pose major obstacles to its study. A small population was then discovered in Vietnam's park, and for the past 20 years, a number of wildlife conservationists have worked closely with the government to try to prevent the species from dying out in Vietnam.With a total population of less than 60 individuals limited to two locations, the Javan rhinoceros is perhaps the most endangered large mammal on earth. Twenty-two of the rhino's dung piles were found in Cat Tien from October 2009 to February 5, 2010, but no dung piles or fresh rhino footprints were seen in the subsequent nine weeks, the 44-page report said.īefore 1988, the Javan rhino was believed to be extinct from mainland Asia. WWF, along with the International Rhino Foundation, confirmed that the last rhino had died in Vietnam by collecting and analyzing its feces. Global demand has also increased in the last four to five years as some people have begun to consider rhino horn a remedy for cancer, Williams said. A small amount of ground-up powder can bring hundreds of dollars on the black market. Horns can now fetch up to $50,000 per pound (about $100,000 per kilogram), the WWF report said Tuesday. (AP Photo/WWF) EDITORIAL USE ONLY WWFĭemand for rhino horn has surged in recent years among Vietnamese and Chinese who believe it can cure an array of ailments. Vietnam has lost its fight to save its Javan rhinoceros population after poachers apparently killed the country's last animal for its horn, international conservation group WWF said in a report Tuesday, Oct. In this photo released by WWF, officials arrange the skeleton of the last rhino in Vietnam in Cat Tien National Park in Lam Dong Province, southern Vietnam. "We're not trying to avoid our responsibility in the death of the rhinos, but we've done our best to protect them," Thanh said.
