INTRODUCTION
Vietnam is a tropical country located in South – East Asia with a total area of about 330,000 km2 ranging from latitude 9o N to latitude 23o N, of which 20 million ha are forest and forest land (about 60% of the country’s area). The country has very abundant and diverse flora containing about 12,000 plant species of which over 7.000 species belonging to 1,850 genera and 267 families have been identified. This flora contains many types of forest ecosystems and a great number of plant species of which many species are rare and valuable from both scientific and economic points of view. The number of plant species utilized by humans for food, medicines, fodder, fibre and raw materials is up to 2,300.
Due to various reasons such as war, shifting cultivation, illegal logging etc, the area of natural forest has decreased considerably. The forest cover was reduced from about 43% in 1943 to 28,2 % in 1987. It is estimated that approximately 60,000 – 100,000 ha of forests are lost annually. The forests and forests ecosystems are in danger, a number of forest plant species have been over – exploited and are in danger of extinction unless effective prevention and protection measures are taken. By unplanned exploitation of forests, not only plant species but also numerous animal species have fewer options for survival because their living habitat is destroyed.
