Summary
- Yellow-cheeked gibbons (Nomascus gabriellae) are present in Nui Ong Nature Reserve.
- A minimum of three groups were estimated to inhabit the site in 2010.
- The population trend is unknown.
- The site has a total size of 255 km².
- Key threats to gibbons are hunting, illegal logging, fires and exploitation of non-timber forest products.
- Conservation activities include community-based patrolling and an awareness campaign.
Site characteristics
The nature reserve is located in Binh Thuan Province, Vietnam. The site supports the southernmost populations of N. gabriellae in Vietnam (Rawson et al. 2011).

Ape status
In 2009 and 2010, at least three groups of N. gabriellae were recorded (Hoang Minh Duc 2010 as cited by Rawson et al. 2011). The total N. gabriellae population is unknown- a survey is needed to update their status in the reserve.

Threats
The main threats to gibbons in the reserve are hunting, agricultural encroachment, illegal logging, exploitation of non-timber forest products and forest fires. The site is surrounded by six communes with over 40,000 people. Wildlife meat, including from primates, is sold at restaurants nearby (Rawson et al. 2011).

Conservation activities
A small project to strengthen management capacity and a community awareness campaign was conducted in the reserve in 2008. Since 2008, nine community-based patrol teams have operated to prevent forest fire, encroachment, illegal logging and hunting (Rawson et al. 2011).
