Habitat and Habits:
Gray langur is more typical of tropical Southeast Asia and southern subtropical arboreal leaf monkey. The main habitat in the tropical rain forest on both sides of rivers and low mountain valley areas, the monsoon forest and southern subtropical monsoon evergreen broad-leaved forest. Altitude habitats of less than 1200m. Their activities, such as foraging and played out mostly on trees, but also often to the ground nitrate pond water. Population size of about 50-60 only for many polygynous polygamy. Start time daily activities mostly around dawn, 9-12 am, gray langur eating and living to persuade frequent peak. Noon (12-13 pm) for the lunch break, often played out in the trees or sit resting, 16-19 pm have an activity peak. Choose tall branches in the vicinity of dense trees sheltered sleep off when it gets dark. Xishuangbanna in southern Yunnan, field size gray leaf Qauqaut group of about 77-81 hectares. With fruits, seeds, buds and petioles as the main food, but also eat fresh branches leaves, buds, shoots, birds and insects, up to more than 80 kinds of food. Reproduction of gray langur in about August to November, February to April next year calving, 6-7 months of pregnancy, lactation period of about four months. March-April before the larvae whole body golden yellow, 5 months after the start of pale gray. 3-4 years old sex can mature. Breeding life of up to 20 years. Population status in the distribution of gray langur is only slightly smaller than our langurs. The estimated population in the early 1980s: there are 10,000 species of Yunnan South -1.5 ten thousand; Yunnan Valencia species are only 1,500-2,000.

To risk factors:
Habitats, especially tropical, South tropical deforestation and reduced forest area, are the main factors causing decrease in the number of gray langur. Such as Yunnan mountainous central immeasurable 1960s to the 1970s, low-lying areas in Lancang River have a more dense virgin forest, there are dozens of group survival gray langur, 70 years since these forests have been completely deforested, gray langur immeasurable mountains almost extinct. 1992 review, leaving only 3-4 group, dozens. Gray langur Ailaoshan area have disappeared. In addition to keeping the situation has had a small part of the zoo keepers, almost did not conduct large-scale breeding.

Existing protection measures:
I have been classified as Class I national key protected wild animals. Yunnan has more than 10 nature reserves (West double version Reserve, Lvchun Mt.Huanglian Reserve, Pingbian Dawei Mountain Nature Reserve, Nature Reserve Jinping watershed, Malipo Laojunshan Reserve, Jingdong Wuliangshan Nature Reserve, Xinping Ailaoshan Reserve, Lincang Snow Mountain Nature Reserve, Cangyuan Nangunhe Reserve, Yingjiang Tongbiguan Gaoligongshan Nature Reserve and etc.) for gray leaf monkey protection. These protected areas and more established in 1980-1986, both national and provincial nature reserves, protected areas, an area of about 536,000 hectares. Since the establishment of protected areas, gray langur habitats have been protected; addition, because the publicity and strict law enforcement, the protection of public awareness, has basically stopped on the gray langur poaching within and outside the protected areas.

Protection measures:
Strengthen the natural habitat and the species protection is a fundamental measure to protect this species. Therefore, proper planning and coordination to develop the local economy and conservation. Meanwhile, should strictly enforce the law forbidding the killing. It should also be strictly controlled including protected areas to carry out captive breeding of this species, so as not to destabilize the wild populations.

Existing situation:
With ornamental and has scientific value. Feeding difficult. Very few wild populations, the Department of i-level protected animals.
