The langurs frequently appear at over 20 sites and divide themselves into small troupes, each with five-seven individuals, including pregnant mothers and baby langurs.

The board has coordinated with relevant sides to study the black shanked douc langurs in order to put forward a preservation plan.

Black-shanked douc langurs are listed as endangered by the International Union for Conservation of Nature and Natural Resources (IUCN). They are indigenous to north eastern Cambodia and southern Vietnam./.
