Viet Nam’s nature is marked by its extraordinary biodiversity that includes over 100 large mammal species, more than 850 species of birds and between 9,600 and 12,000 plant species. Arguably it is one of the world’s ten most biologically diverse countries that hosts about 10% of the world’s species.

Among Viet Nam’s critically endangered mammals are the Cat Ba Island golden-headed langur, Javan rhinoceros, Sumatran rhinoceros and the white-rumped black lemur. Endangered Asian elephants, tigers, otter civets and parti-coloured flying squirrels have also been spotted.

Viet Nam is dedicated to preserving its vast natural resources. Thirty National Parks and over 70 Nature Reserves and conservation areas have been established.  It further includes two Ramsar sites, four Biosphere Reserve sites, and five World Heritage sites.

Halong Bay

Boats in Halong Bay, Viet Nam, Mekong Responsaible TourismSituated in the north-east region, Halong Bay is a part of the Bac Bo Gulf and comprises the sea area of Halong City, Cam Pha Town and a part of Van Don island district, Quang Ninh Province. It borders Cat Ba Island to the southwest, and the mainland to the west with a 120km-long coastline.

Halong Bay covers a total area of 1,553km², including 1,969 islands of various sizes; the average geological age of the islands is between 250 and 280 million years old. The beauty of Halong Bay does not consist only in the forms of its mountains, islands and the colour of its waters, but also in its infinitely rich system of grottoes and caves. Each is a grandiose and refined natural architectural creation.

Results of scientific research show that Halong Bay features the ecosystems of a tropical ocean region such as a coral reef ecosystem with 232 species of coral. It is also home to 81 species of gastropoda, 130 species of bivalvia, 55 species of polycheta and 57 species of crab. Also living in this ecosystem are a great many species of animals: migrating birds (200 species), polycheta (169 species), seaweed (91 species), and reptiles (10 species).

This is not all, Halong has been proved by scientists to be one of the first cradles of human existence in the area, with such archaeological sites as Dong Mang, Xich Tho, Soi Nhu and Thoi Gieng…

In 1994, Halong Bay was recognised as World Natural Heritage for its natural beauty, and in 2000, Halong Bay was recognised as World Natural Heritage for the second time based on its geological value. The classified area covers 434km², comprises 775 islands and forms a triangle. It is now seriously threatened by mass tourism, years of dynamite fishing, polluting tourism boats and bad practices.
