Appearance

The Indochinese grey langur is a Old World monkey native to East and Southeast Asia.

Range and habitat

This species is found throughout Indochina, from northern Thailand east to Vietnam and west to eastern Myanmar, and ranges north to southern China south of the Salween River. Unlike langurs that live in karst forests, that have a largely terrestrial lifestyle, the Indochinese grey langur inhabits old-growth evergreen forests and has a largely arboreal lifestyle.

Habitat labels include forest.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

In crisis

This species' population is only thought to have about 2,400 to 2,500 mature individuals. It is threatened by habitat destruction and, especially in Vietnam and Laos, hunting, the latter of that is thought to have led to rapid declines in the species.

Indochinese grey langur is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
