• Northern white-cheeked gibbons (Nomascus leucogenys) are present in Long Luong Commune.
• Two groups are reported to inhabit the site (one group confirmed through a survey).
• The gibbon population trend is unknown.
• The size of the area is unknown.
• Key threats to gibbons are hunting and shifting agriculture leading to forest fragmentation.
• Conservation activities are not documented.

Ape status

In 2011, a short survey documented one out of two gibbon groups that had been reported at the site by local villagers. The groups are located on either side of a valley entirely used by local communities (Rawson et al. 2011). Village interviews indicate that the gibbons in the site are white-cheeked gibbons; however, field observations were not able to confirm this. Furthermore, museum specimens of N. concolor were collected in a nearby area (Long Sap Commune) in 1963 (Rawson et al. 2011).

Nomascus leucogenys	2011		2		Long Luong Commune, unknown size of area	Interview	Rawson et al. 2011	One group was confirmed during a short survey; based on interviews with local villagers, there are two groups.

Threats

The population is no longer viable, being so small and the two groups separated from one another (Rawson et al. 2011). Wildlife in the area are threatened by hunting and shifting agriculture, which has left small isolated patches of forest. Several years ago, local villagers of Mong ethnicity protected local gibbon groups because they were perceived as harmless and there was a local superstition that killing gibbons can bring bad luck (Rawson et al. 2011).
