The Cao Vit Gibbon is critically endangered on @IUCNredlist in #China #Vietnam. 80% of their forest home has been destroyed for #palmoil #timber and other crops. Help them survive by joining the brand #Boycott4Wildlife

The Cao Vit Gibbon is listed as Critically Endangered because of an observed population decline of at least 80% over the past 45 years (three generations), primarily due to hunting and habitat loss. This species historically inhabited lower montane and limestone forests, in a wet tropical monsoon climate, at an altitude range of 50-900 m (Tien 1983). The known population is now entirely restricted to limestone forests on poorly accessible karst outcrops ranging between 500-930 m in elevation (Rawson et al. 2011). It is now restricted to the Cao Vit Gibbon Conservation Area, Vietnam, and Bangliang Nature Reserve, China, which comprises a total of 2,500 ha of limestone forest straddling the Sino-Vietnamese border (Fan et al. 2013a).

Numerous conservation efforts of these rarest of small primates are ongoing.
