According to the Biodiversity Action Plan of the Government of Socialist Republic of Vietnam, the extinction rate of Vietnam in last decades is higher than that of the world, and 1000 times higher than the natural extinction rate. The most dangerous threats to biodiversity are expansion of economic (cultivation) activities, poaching and deforestation. Rhino is among the most endangered species. The number of rhinos decreases from 15-17 in 1970 to 3-7 today. Among more than 350 endangered species in Vietnam, rhinos is the most endangered one. Rhino, together with elephant, are the two biggest animal on land. Among 5 species of rhinos in the world, there are 3 types of Asian Rhinos: Indian Rhino (the Greater one-horned rhinoceros), Javan Rhino (Lesser one-horned rhinoceros) and Sumatran Rhino (Asian two-horned rhinoceros). The three are “among the most remarkable animals on earth and are of great cultural importance in Asia” (Foose and Strien. 1997, p. 5)
