Asia > Vietnam > Muong La Watershed Protection Forest
Summary
- Western black crested gibbons (Nomascus concolor) are present in Muong La Watershed Protection Forest.
- A minimum population of 6 groups was confirmed in 2010.
- The gibbon population trend is decreasing.
- The site has a total size of 30 km².
- Key threats to gibbons are hunting, and habitat encroachment and degradation.
- Conservation activities have focused on gun confiscation and community-based patrols supported by FFI.
Site characteristics
The site is located in Muong La District, Son La Province, Vietnam.

Ape status
The N. concolor population in Muong La Watershed Protection Forest was surveyed four times between 2000 and 2010, at the same time as surveys in Mu Cang Chai SHCA (Rawson et al. 2011). A 2010 survey recorded at least six gibbon groups and a minimum of 12 individuals, within a population of 20 groups including those in Mu Cang Chai SHCA (Le Trong Dat & Le Minh Phong 2010). This is significantly less than in 2008 (also six groups but with >17 individuals) and 2007 and 2006 (14 groups with >43 individuals), suggesting a decline (Rawson et al. 2011).

Threats
Hunting has been the main threat to gibbons at the site since the mid-2000s and it continues (Rawson et al. 2011). In January 2010 a hunter shot one male gibbon and sold it to a wildlife trader in Muong La Town for VND 1,800,000 (about US$ 90) and in September 2009, the same trader purchased two gibbon skins and skeletons from hunters (Le Trong Dat & Le Minh Phong 2010). The forest has been extensively logged for high value timber species such as Fokienia hodginsii both legally and illegally (Le Trong Dat & Le Minh Phong 2010). The watershed forest has also been cleared for agriculture and rubber plantations. Hydropower development has led to forest clearance in the inundation zone and displacement of communities, which have been resettled in forest areas, causing further forest loss for agriculture and home construction. In addition, due to a lack of productive agricultural land many displaced people have turned to illegal logging as an income source (Rawson et al. 2011).

Conservation activities
FFI established a community-based gibbon monitoring group in Muong La in 2004, similar to the model in Mu Cang Chai. These patrols continued until 2007 due to the end of project funding. In 2005, a gun confiscation and awareness campaign was conducted (1,800 guns were confiscated). The results of the gibbon survey in 2006 seemed to indicate that these conservation interventions were successful, although why it should be so with less intervention than in Mu Cang Chai remains unclear (Swan unpublished data; Rawson et al. 2011). A steep decline then appears to have occurred from 2007 when patrolling ceased and increased migration to the area occurred due to the hydropower development. The patrol group was re-established by FFI in 2010, but pressures remain high (Rawson et al. 2011).
