Viet Nam is the 16th most biodiverse country in the world. The country is estimated to contain nearly 10% of the world’s animal species and nearly 40% of its plant species are endemic. Viet Nam is home to several of the world’s iconic species, with 109 large mammals and 850 bird species recorded. This high level of diversity is significant for a relatively small country of 33.12 million hectares. Viet Nam’s terrestrial, freshwater, and marine ecosystems support nearly 50,000 species, including nearly 7,500 micro-organisms, 20,000 terrestrial and aquatic plants, 10,500 terrestrial animals, 2,000 invertebrates and freshwater fish, and over 11,000 marine species.
At least 1,200 freshwater species live in the Mekong River, including the last remaining populations of the Irrawaddy dolphin, the giant freshwater stingray, and the Mekong giant catfish. The Mekong Delta is one of the largest on earth and contains a wealth of globally important wildlife including rare and threatened bird, mammal, fish, amphibian, reptile and invertebrate species. Iconic species include the endangered Sarus Crane, the giant Mekong catfish, the Hairy-nosed Otter, the Spoon-billed Sandpiper and around thirty species of mangrove.
The Central Annamites shelter some of the planet’s most spectacular, mysterious and highly threatened animals including the critically endangered and endemic Saola, large-antlered muntjac, Truong Son muntjac, Owston’s civet, striped rabbit, and crested argus. With 25 primate species, 11 of which are critically endangered and 5 of which are endemic, Viet Nam is considered one of the most important countries for primate conservation. Meanwhile, once abundant in Viet Nam, the wild Asian elephant population in the country has been reduced to over 100 individuals.
