Annamese Range

The Annamese Range stretches along the eastern side of the Mekong basin, separating its tributaries from rivers that descend toward the coast of Vietnam. Forested ridges and deep valleys form a long barrier through mainland Southeast Asia. Moist evergreen forests cover parts of the mountains and their foothills, sheltering a rich variety of plants and animals. Mountain streams carry the monsoon rains toward the river systems on either side.
