Site characteristics

Pu Hoat Nature Reserve is located in the northwestern part of Vietnam’s Nghe An province. The reserve was established in 2013. The site is rich in biodiversity, providing habitats for a broad and diverse range of plants and animals, including northern white-cheeked gibbons (USAID).

Ape status

The first gibbon survey was conducted in 2002. In 2009 and 2010, five gibbon groups were recorded and the possible occurrence of 2-3 others was identified. At least four groups were recorded in 2007, at least three groups in 2003 and five groups in 2002. Most survey effort has focused on the northern part of the area, which is contiguous with Xuan Lien Nature Reserve and holds most gibbons. The southern and central parts of the reserve contain few gibbons and with little chance of long-term survival (Rawson et al. 2011).

Threats

Hunting is the main threat to N. leucogenys in this site. Hunters with guns and dogs, and trap lines are frequently observed. Gibbon hunting has been prevalent since at least the 1990s, when juvenile gibbons from the reserve were sold for the pet trade. Over the past decade, at least five gibbons have been sourced from the reserve: two stuffed gibbons for sale in 2009, a live male gibbon for sale for VND 400,000 in 2010, a captive female for sale for VND 1.5 million and a reported juvenile which died in captivity in 2005 (Rawson et al. 2011).
