Establishment of the snub-nosed langur conservation area

Fauna and Flora International (FFI) has cooperated with the Government of Vietnam to establish a conservation area for the snub-nosed langur in Khau Ca forest area, Ha Giang province.

This conservation area is called “Ha Giang snub-nosed langur species and habitat conservation area” with a total area of ​​up to 2,000 hectares for 90 snub-nosed langurs. This langur has the scientific name Rhinopithecus avunculus and usually lives in subtropical forests.

However, due to deforestation, there are only about 200 left in the world, divided into 4 types, of which 3 are in China and 1 in Vietnam. The snub-nosed langur is the rarest primate in our country, appearing only in two provinces of Ha Giang and Tuyen Quang. Previously, the snub-nosed langur was almost extinct but was rediscovered in 1990 in Na Hang district, Tuyen Quang province.  

Protection and development of snub-nosed monkeys

  • Khau ca snub-nosed langur habitat management board. And Ha Giang Provincial Forest Protection Department has functions and duties to enforce the law on forest protection and management. To ensure the survival of the snub-nosed langur as well as other creatures in Khau Ca area.
  • The San Diego Zoo in the United States plays a key role in the conservation of langurs in Asia. San Diego Zoo worked with the Ha Giang Forest Protection Department, the management board of the Khau Ca snub-nosed langur species and conservation area, and partners to find a possible solution for human symbiosis. as well as other animals and plants in Khau Ca.
  • Denver Zoo USA has also participated in the conservation project of the snub-nosed langur since 2009.
