In 2009, Chetry et al. (2012) recorded 33 gibbons in 10 groups based on direct sightings in the reserve forests of Hal logaon, Kukurmara, and Kundil Kalia (Chetry et al. 2021). In 2019, 17 individuals in seven groups in these three reserve forests were recorded, indicating a 48.5% population decline. The number of groups was also reduced from 26 (direct observations and call-count) in 2009 to 11 in 2019 (Chetry et al. 2021). In this time frame there was also a 18.75% increase in the proportion of adults to immatures, indicating reduced recruitment and population decline (Chetry et al. 2021).

Lack of long-term funding for continuity of conservation activities and lack of a national gibbon action plan, which exists for other endangered species in the country, but not for gibbons (Chetry pers. comm. 2023).
