ABSTRACT
Vietnam comprising the largest area in the eastern part of the Indo-Chinese Peninsula is situated along the Southeastern margin of the Peninsula. The hydrographic network within Vietnam is well developed within addition to numerous small and medium-sized streams and rivers. Within Vietnam, the geographical distribution of biodiversity across the country is uneven. The varied pattern of biodiversity across the country can be illustrated in a number of ways, depending on the number of factors taken into account. Vietnam biodiversity both for Flora and Fauna is considered as typical of the Oriental region in Biogeographical analysis. The biodiversity of Vietnam has been decreased quickly. Some of the main reasons are: land conversion without a proper scientific base, surface areas of natural forests are reduced quickly; Infrastructure developments, building up many dams, roads, new urban and rural human settlements; and overexploitation of Natural resource/Illegal exploitations in fishing, hunting, forestry.
