Ape status
In 2011, a group of five individuals was seen in a forest patch of about 300 ha in Sai Khao Village, Muong Cai Commune. However, no gibbons were detected in the nature reserve itself (Rawson et al. 2011). Based on a large mammal survey conducted later in 2011, the population of gibbons in the reserve is now extirpated, but one group of 3-4 individuals was recorded in the buffer zone. Local reports of gibbons had been documented in previous wildlife surveys in the 90s (Rawson et al. 2011).

Threats
The main threats to gibbons and other wildlife in the reserve are hunting, logging, and forest loss due to the expansion of agricultural land; forest fires from human encroachment also occur annually (Rawson et al. 2011).

|---|---|---|---|---|---|
| 1. Residential & commercial development | Unknown | ||||
| 2. Agriculture & aquaculture | 2.1 Annual & perennial non-timber crops | High | Habitat encroachment as a result of agricultural activities (Rawson et al. 2011). | Ongoing (2011) | |
