Critically Endangered

Location: N.W. Vietnam, N.W Laos

Northern White-cheeked Gibbon is critically endangered on @IUCNredlist in #Vietnam and #Laos due to hunting, pet trade and #deforestation for #palmoil. Save this species by making art and joining the #boycott4wildlife

The Northern White-cheeked Gibbon is considered Critically Endangered based upon the combined effects of habitat loss, hunting and live capture for the pet trade. The last population in China apparently disappeared several years prior to this species’ last assessment. In Laos and Vietnam, hunting and live capture continue and will likely do so over the long-term.

IUCN Red List

The Northern White-cheeked Gibbon is a diurnal, arboreal and territorial species of gibbon found in tall primary and degraded evergreen and semi-evergreen forest. In northwestern Vietnam and northern Lao PDR, the animals live in a subtropical climate with a short and not very cold winter without frost (Tien 1983).

In Vietnam, the species is found from 200 m to well over 1,000 m asl, with the highest record coming from Pu Mat NP from a listening post positioned at 1,500 m asl (Rawson et al. 2011), however, individuals are now found mostly above 700 m due to lowland deforestation (Rawson et al. 2011). In Lao PDR, gibbons are found from the Mekong plains up to at least 1,650 m in Nam Et-Phou Loei NPA (Duckworth et al. 1995, Duckworth 2008).

These gibbons belong to genus Nomascus. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other and form monogamous breeding pairs. Males and females have different coloured fur.

Numerous conservation efforts of these rarest of small primates are ongoing. Sponsor a gibbon at a rescue centre here.
