The distribution of the eastern hoolock gibbon in India is restricted to the eastern part of the state of Arunachal Pradesh and the Sadiya sub-division of Assam. The Sadiya population of the eastern hoolock gibbon is the sole population of the species in the state of Assam. A survey was conducted from January to February 2019 in three of the six reserve forests of the Sadiya sub-division to investigate the status of the eastern hoolock gibbon. Data were collected using modified line-transect surveys. We recorded seven groups in three reserve forests through direct sightings. Of the 17 individuals recorded, 14 were adults, and three were juveniles or infants. The average group size of the sighted groups was 2.42, with an adult sex ratio of 1:1. We also recorded 12 groups of rhesus macaques in the area. Rapid loss of habitat resulting from encroachment and illegal felling of trees and inadequate infrastructure are the major threats to the hoolock gibbon in Sadiya. A comparison of the present demographic data with the results of a previous study indicates that, without any immediate conservation and management intervention, this single population of eastern hoolock gibbons will be extinct in the near future. An integrated management program for the forest fragments, taking hoolock gibbon as a flagship species, could ensure the survival of the biodiversity of Sadiya, and the hoolock gibbon there.
