Viet Nam is known that is a center of world’s species diversity with a abundant natural ecosystems like: mangrove forests, limestones, seas v.v with characteristics of the tropical climates. It is a habitat and development of many endemic wild species valuable, some of them can’t be found anywhere else in the world. Viet Nam has many valuable wild genetic resources, especially medicinal plants, the flowers and tropical plants, v.v. Biodiversity in Vietnam is the great value in many different aspects of ecological, economic and social. Ecological values and the environment represent at the biodiversity, helps to protect soil and water resources, make the climate equable, disintegrate waste matter. Economical value clearly indicates the contribution of the sector closely linked to biodiversity to the economy such as agriculture, forestry, fisheries, tourism. The human’s values of biodiversity contributed to the human’s education, created jobs, stabilize the social order In 1992, the World Conservation Monitoring Center evaluated Vietnam as one of the 16 most biologically diverse countries in the world. In Species diversity, we have about 11,458 species of fauna, 21,017 species of flora and 3,000 species of micro-organisms have been recognized and every year many new species are discovered. For example, in period of 1993-2002, 13 new genera, 222 species, 30 subspecies were described and 2 families, 19 genera, over 70 species were added to the native flora. Five new mammal, 3 bird species in mainland Southeast Asia and large number of new species of reptiles, amphibians, fishes and invertebrates have been described for 30 years. However, biodiversity in our country is rapidly degraded, areas of natural ecosystems are shrinking. Number of species and number of individuals of each species are decreasing. Many valuable wild species are declining strongly in numbers, or threatened with extinction at high level. The wild genetic resources are in recession faster and...
