International Status

IUCN Red List Category

ENIUCN

Justification

The species is listed as Endangered as there has been a decline of over 50% in the last 3 generations (approximately 40 years) due to forest loss. This decline is continuing, though in some areas the populations are declining at a lower rate.

Ecology Discription

Appearance

Habitat

This species is found only in montane forests where snow cover can last for up to six months of the year (Allen 1938; Davison 1982). In the Qinling Mountains it is found in mixed deciduous-broadleaf forests from 1,400 to 2,800 m (Gao and Liu 1995; Li et al. 2001). It can also occur in other forest types, including mixed conifer-broadleaf and deciduous broadleaf. Rhinopithecus roxellana roxellana and Rhinopithecus roxellana hubeiensis are found more often in mixed conifer and deciduous broadleaf forests.

IUCN

Population size

Rhinopithecus roxellana roxellana
There are about 10,000 individuals in 100 troops in Sichuan (6,000 individuals in Mingshan Mountain, 3,500 in Qionglaishan Mountain, and 500 in Daxiangling and Xiaoxianling Mountain), about 800 individuals in 8 troops in Gansu, and about 170-200 individuals in 1 or 2 troops in Shaanxi (Zhang 1995; Jiang 2005; Li unpubl. 2006).

Rhinopithecus roxellana qinlingensis
There are approximately 3,800-4,000 total individuals belonging to 39 troops (Li et al. 2001). Around half of these are mature individuals. Since the mid 1990s, the population appears to have stabilized.

Rhinopithecus roxellana hubeiensis
There are about 600-1,000 individuals in 5-6 troops (Ren et al. 1998).

IUCN

Behavior

Diet

It is semi-terrestrial, diurnal, and folivorous, but will also eat seeds, fruit, bark, insects, and small vertebrates.

Threat

Major Threat(s)

Rhinopithecus roxellana
The major threat for the species is forest loss due to agricultural expansion, especially outside of protected areas.

Rhinopithecus roxellana roxellana
The major threat is habitat loss. Secondarily, there is a serious threat from continued illegal hunting of this subspecies. There is also harassment owing to tourist activities, including the herding of troops for tourists to view.

Rhinopithecus roxellana qinlingensis
In the Qinling Mountains tourism is having a significant negative impact, mainly due to the creation of roads and other infrastructure. Before 1990, there were threats from illegal hunting, but this has stopped due to increased government protection.

Rhinopithecus roxellana hubeiensis
There is a serious threat to this subspecies from tourism-related activities, along with continued habitat loss. Before 1990, there were threats from illegal hunting, but this has stopped due to increased government protection.
