Based on a total suitable habitat of 22,800 ha, the total number of groups inside the national park is estimated to be 124 (95% CI: 122-132).

Summary
- Southern yellow-cheeked gibbons (Nomascus gabriellae) are present in Bu Gia Map National Park.
- It has been estimated that 124 (95% CI: 122-132) groups occur in the site.
- The gibbon population trend is unknown.
- The site has a total size of 260 km².
- Key threats to gibbons include logging, agricultural encroachment, hunting, and illegal pet trade.
- Conservation activities have focused on environmental education, species threat assessments, and training of park staff in survey methods.
Site characteristics
Bu Gia Map National Park is located in southern Vietnam. Together with Cat Tien National Park, the parks hold the largest population of southern yellow-cheeked gibbons in the country (Rawson et al. 2011).

Ape status
At Bu Gia Map National Park, gibbon populations are partly contiguous with those in other Vietnamese sites as well as Seima Protected Forest in Cambodia (Rawson et al. 2011). Cat Tien and Bu Gia Map National Parks are key sites for the conservation of N. gabriellae in Vietnam; Bu Gia Map National Park supports one of the largest known populations (Rawson et al. 2011). In 2010, a population census over an area of 16,500 ha using 36 listening posts estimated 0.54 groups/km2 (95% CI: 0.51-0.58) (Rawson et al. 2011). Based on a total suitable habitat of 22,800 ha, the total number of groups inside the national park is estimated to be 124 (95% CI: 122-132). In 2007, at least 200 individuals were estimated to occur in the park (Luu Hong Truong et al. 2007).

Threats
Gibbons are commonly held as pets in hotels and private zoos in southern Vietnam; most of these individuals are likely sourced from the wild. In 2010, hunting with guns was frequently observed in the commune and nearby Bu Gia Map National Park. Additionally, agricultural encroachment, illegal logging, exploitation of non-timber forest products and infrastructure development are key threats to biodiversity in this park (Rawson et al. 2011).

Conservation activities
Species threat assessments, environmental education activities and training of park staff in gibbon survey techniques is implemented at the park (Rawson et al. 2011).
