Safeguarding endangered Douc Langurs and critically endangered Gibbons at Son Tra Nature Reserve and Chu Mom Ray National Park, Vietnam

08.07.2016

Conservation Problem

Doucs Langurs and Gibbons face various severe threats throughout their range.

Douc Langurs are trapped to supply live animals for wildlife trade, or they are shot for food and to make medicines such as monkey glue. Hunters locate Gibbons by their calls and are ready to kill as many as 20 females to obtain just one live infant for the wildlife pet trade. Loss of group members, especially female Gibbons and male Douc Langurs, disrupt the breeding potential of entire social groups.

Moreover, logging and agriculture often reduce these animals' habitat so that they are found only on fragments of their previous ranges.

Project Activities

The Douc Langur Foundation's project team will train local staff and conduct monthly snare and trap patrols, removing and destroying traps, dismantling poachers' camps, capturing and arresting hunters and releasing healthy live animals.  Patrols will also confiscate injured animals, guns, and hunting and logging equipment.

Confiscated Douc Langurs and Gibbons will be transported to care centres and when possible returned to their forest homes.

Local Douc Langurs and Gibbon protection teams will furthermore protect the species' sleeping and feeding areas taking into consideration a variety of threats for the species.

Project Outcomes

Patrol teams trained and equipped with new skills will be particularly efficient in protecting populations of Douc Langurs and Gibbons. Snare and trap patrols should immediately reduce hunting, poaching and wildlife trade in Son Tra Nature Reserve and Chu Mom Ray National Park. With time, increased law enforcement will reduce the incidence of illegal activities.

Based on experience at other locations the project expects to see a rapid decrease in the number of Gibbons for sale or kept as pets in nearby villages and towns such as Kon Tum or Danang. Confiscated animals will be cared for and returned to the forest.


Local people will learn that actively protecting Gibbons and Douc Langurs can bring them economic rewards over the long term.
