About the Annamites Ecoregion

Annamites - Covering over 23 million hectares

Lying to the east of the Mekong River, the long chain of mountains called the Annamite Mountains of Indochina and the lowlands that surround them make up the Greater Annamites ecoregion.

This area encompasses an incredibly broad, diverse and special range of habitats, animals and plants, accounting for a remarkably rich biodiversity.

Includes the Da Lat range
The term Annamite Mountains normally refers to the blocks of mountains lying between Lao P.D.R and Vietnam, only. However, as the entire mountain range south of the Da Lat plateau is ecologically similar to the Annamite mountains, it has been included in the ecoregion (maps).

Reaching over 2500 m
The Greater Annamites ecoregion straddles the Laos-Vietnam border for over 1100 km, includes small parts of Cambodia, covers over 23 million hectares and rises to over 2500 m at its highest point.

Also known as...
Although the term Annamite is used
here, the mountain range is more commonly known as Truong Son in Viet Nam, and as Sai Phou Louang in Laos.

Many species found no-where else
Many species are exclusive to the ecoregion. Indeed, one of the greatest concentrations of endemic species in a continental setting are found here, including the beautiful and threatened douc langur (Pygathrix nemaeus). Other species include the Asian tiger and elephant, and the Javan rhinoceros.

Ethnically diverse
More than 30 ethnic groups live in the Annamites, each with their distinctive and traditional music, language, dress and customs. The natural resources of the Greater Annamites are vital to all of the people.
