The douc monkey has a length of 61 - 76 cm (24 - 30"). It is found in tropical
rain forest and monsoon forest, including both primary and secondary forest, from sea
level to 2000 m (6560'). Its diet is comprised of a variety of leaves and certain fruits.
The douc monkey is arboreal and diurnal. Groups of douc monkeys usually consist of 4 -
15 individuals. They include 1 or more adult males, and usually about twice as many adult
females as males.
In 1967 the douc monkey was thought to occur in China
(only from 1 female recorded from Hainan Island), Laos
and Vietnam. In the early 1980's, it was reported
to occur only in Laos and Vietnam. By 1996 it was thought to occur in Cambodia, China,
Laos and Vietnam.
Reasons for the douc monkey's decline include hunting for food by natives and military
personnel; loss of its forest habitat; and environmental disruption by military activity
during the Viet Nam War, including the widespread use of defoliants and bombing.
*** As of 1967 the douc monkey was completely unstudied. Even by 1987 little was known of its habits in the wild.
2004: Occurs in Cambodia, Laos and Vietnam (IUCN 2004).

In the early 1980's, it was reported to occur only in Laos and Vietnam. By 1996 it was thought to occur in Cambodia, China, Laos and Vietnam. In 2000 it was reported to occur in Cambodia, Laos and Vietnam.
