Introducing the Greater Truong Son Conservation Action Plan
For many of these species, their loss from this region would
mean their loss forever. It is for this reason that the Greater Annamites was recognised as one of the “Global 200” Ecoregions of highest international conservation priority.
The Greater Annamite Mountains comprise the Truong Son in Vietnam and the contiguous Saiphou Louang in Lao PDR.
The region’s international importance for biodiversity conservation is directly linked to its value to the economies of Vietnam and Lao PDR.
The ecosystem services the area provides in its natural state in the form of climate moderation, erosion control and generation of clean water are a critical, irreplaceable component of the resourcebased economies of two nations.
The area is also important to the welfare of the wider region
because some of the most important tributaries of the Mekong River arise in and flow through the Greater Annamites. The condition of the Annamites watershed affects the livelihoods of millions who depend on fishing and farming downstream.
The Vietnamese section of the ecoregion, Truong Son, is both the most extensive and also the most diverse. The mountain influence on the monsoons gives the Vietnamese section both the wettest and the driest climate in the Greater Annamites.
The majority of the wettest evergreen forest occurs within Vietnam as do most of the highest peaks. The highest degree of endemism is found on the eastern flanks of
the mountains, however its forest and river ecosystems are the most seriously degraded and fragmented in the ecoregion and are now represented in relatively small patches.
