  • Title
    Status and conservation of Eastern Hoolock Gibbon Hoolock leuconedys in Assam, India
    Type
    Journal Article
    Description
    A field survey was conducted in 2010 from March to May in the reserve forests of Sadiya sub-division, in the Tinsukia District of Assam, India, to investigate the status of the Hoolock Gibbon. The data were collected using modified line-transect and call-count methods. We recorded 10 groups of gibbons in three reserve forests, through direct sighting. Of the 33 individuals recorded through direct sighting 63.6% were adults, 21.2% juveniles and 15.2% infants. The average group size of the sighted groups was 3.3 individuals, with an adult sex ratio of 1:1.1. We also recorded 10 groups of Rhesus Macaques in the area. Anthropogenic pressures included encroachment, felling of trees and inadequate infrastructure, and these were the major threats for Hoolock Gibbon and other wildlife in the region. Notably, the gibbons of Sadiya have been identified as the Eastern Hoolock Gibbon Hoolock leuconedys and this is the first report of the species from Assam.
