Keywords:
Gibbon population density, gibbons distribution, Kon Ka Kinh National Park, Northern yellow-cheeked gibbon (Nomascus annamensis)Abstract
This study aims to investigate the status of Nomascus annamensis in Kon Ka Kinh National Park and propose a solution to conserve this population. Data collected from November 16, 2016 to December 31, 2016 at 21 survey sites, using community interviewing, auditory sampling methods, pointbased surveys, and gibbon song recordings. The results recorded the song of 11 gibbons group at 10 listening spots. The gibbon density was estimated at 0.11 groups per km2. Gibbon distribution was recorded in Forest Unit Area such as 18, 68, 74, 79, 91, 92, 95, 104, 105, 110, 414, 433...the main threats to Northern buffed-cheeked are habitat loss and poaching.The habitat for gibbon inside the National Park as well the adjacent areas should be strictly protected. Controlling guns owned illegally by local people in the buffer zone. The data in listening post of this research can be used as a database for Gibbon monitoring activity of the rangers in Kon Ka Kinh National Park
