Endangered

Bangladesh, India, Myanmar

Existence uncertain: China

The Hoolock Gibbons are three species located in South Central Asia. They are the second largest of the gibbons after the Siamang. They have rings around their eyes and mouths giving them a mask-like appearance. Like other gibbon species they call to each other in regionalised accents, have long swinging arms and superior acrobatic skills.

Western Hoolock Gibbons are the only ape species in #India. Once also found in #China their existence there is now uncertain. Endangered by #meat #agriculture expansion. Support their survival with a #Boycott4Wildlife on brands destroying their home.

The Western Hoolock Gibbon is a forest-dweller that, depending on its locale, inhabits tropical evergreen rainforests, tropical evergreen and semi-evergreen forests, tropical mixed deciduous forests, and subtropical broadleaf hill forests. It has also been noted in bamboo “brakes” and hollock (Terminalia myriocarpa) and ajhar (Largerstroemia flosreginae) plantations. One gibbon pair in the Borajan Reserved Forest (north-east India) was observed to habitually descend from the trees to move over scrub and short bamboo especially while trying to reach the isolated food trees inside a village. This pair was found sleeping at heights of 0 m or less in bamboo clumps (Kakati 1997).

Although gibbons may be moving through, or sleeping in, bamboo forest or plantations, they cannot survive in monocultures such as palm oil (W. Brockleman pers. comm.)

IUCN Red List

The Western Hoolock Gibbon remains Endangered, based upon a suspected population reduction of at least 50% over the period of three generations (2001-2015, 2016-2030 and 2031-2045), based on ongoing and significant levels of forest loss in Bangladesh, northeastern India and Myanmar, combined with ongoing and similarly significant levels of subsistence hunting and live capture for the pet trade throughout the species’ range.

Affecting all northeastern Indian primate populations are harvesting of bamboo for paper mills, oil mining and exploration, and coal mining, which deplete habitat and cause pollution and disturbance (Choudhury 1991). Habitat fragmentation and loss are major threats in India (Kakati 2000).

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, scientists, conservationists, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail and industrial agriculture sectors and through strong campaigning we can stop them cutting down forests. Be bold! Be courageous! Join the #Boycott4Wildlife and stand up for the animals with your supermarket choices
