	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).
