There is also a very lucrative and illegal wildlife trade for the red-shanked douc.

The main predator of the red-shanked douc is humans.

Like other doucs, the red-shanked douc is a long, slender monkey.

The red-shanked douc is thought to be found only in north and central Vietnam and Laos.

The red-shanked douc is diurnal and eats and sleeps in the trees of the forest.

The red-shanked douc characteristically has bright maroon legs and reddish patches around the eyes.

The red-shanked douc has a low-pitched growl that is given as a threat, and a short, harsh distress squeal.

Both have dappled grey bodies, black hands and feet and white cheeks, although the cheek hairs of the red-shanked douc are much longer.

The red-shanked douc (Pygathrix nemaeus) is a species of Old World monkey, among the most colourful of all primates.

Asian Elephant, White-cheeked Gibbons and Red-shanked Douc langurs are the mammal species recorded but detailed list of mammals in the park is yet to be prepared.

The mammal fauna of the park is not well known, though historically it held important species such as Asian Elephant, White-cheeked Gibbons and Red-shanked Douc langurs.

The red-shanked douc is on the IUCN Red List of endangered species, and CITES I prohibits international trade.

Endemic mammals recorded are five and these are: Northern White-cheeked Gibbon, Red-shanked Douc, Truong Son Muntjac and Annamite Striped Rabbit.

When the group is untroubled, the red-shanked douc will move noisily from branch to branch through the forest, crashing through foliage, swinging under branches and leaping with two feet together, displaying its remarkable sense of balance.

This project is sponsored by Zoologische Gesellschaft Frankfurt (Germany) in order to provide a sanctuary for 10 species of primates, including Trachypithecus francoisi hatinhensis, Red-shanked Douc langur or Pygathrix nemaeus nemaeus.

The mammal species protected under the Nam Kading National Protected Area are four Critically Endangered and Endangered primate species of the Northern White-cheeked Gibbon, the Southern White-cheeked Gibbon, Red-shanked Douc Langur and two Leaf-monkey species.
