Leaflet

• Southern Yellow-cheeked Gibbons (Nomascus gabriellae) are present in Chu Yang Sin National Park.
• It has been estimated that a minimum of 8 groups occur in the site.
• The gibbon population trend is unknown.
• The site has a total size of 669 km².
• Key threats to gibbons are hunting and logging.
• Conservation activities have focused on improving the management of the site, e.g., improvement of law enforcement.

Site characteristics

The site is located in southern Vietnam; it was initially designated as a nature reserve in 1986, and designated as a national park in 2002 (BirdLife International 2023, WDPA). The park encompasses a range of high mountains in the northern part of Da Lat plateau. Endemic bird species have been recorded at the site, the most important of which, from a conservation perspective, are Grey-crowned Crocias Crocias langbianis and Garrulax yersini, which are classified as globally endangered. The site was designated an Important Bird Area in 2002 (BirdLife International 2023).

Ape status

In 2010, eight groups of southern yellow-cheeked gibbons were recorded in an area of 2,500 ha within the park, documenting the first recent evidence of their presence (Rawson et al. 2011).

Threats

Infrastructure development, logging and hunting are key threats to wildlife in this park (Rawson et al. 2011).

Category	Specific threats	Threat level	Description	Year of threat
10 Geological events		Absent
12 Other threat		Absent
5 Biological resource use	5.1 Hunting & collecting terrestrial animals	Present (unknown severity)	An influx of Mong ethnic communities has led to an increase in gun ownership and hunting around the park, however, there are no records of gibbons hunted or traded from this site, although southern yellow-cheeked gibbons are a target species for hunters with guns (Rawson et al. 2011).

IUCN Threats list

Conservation activities

A GEF project was implemented from 2006-2009 to strengthen management, including wildlife surveys and capacity building of local management agencies. Further support is required for activities which would also assist the conservation of southern yellow-cheeked gibbons, including park expansion and improved management capacity and law enforcement. Gibbon population surveys are needed to further determine the value of the site for gibbon conservation (Rawson et al. 2011).
