Eastern Black Crested Gibbon range
(excluding Hainan Black Crested Gibbon (Nomascus nasutus hainanus) range)Hainan Black Crested Gibbon range The eastern black crested gibbon (Nomascus nasutus) is a species of gibbon that was once widespread in China and Vietnam. There are two subspecies.
It became extinct on the continent in the 1950s; and now roughly only 20 gibbons of the subspecies Nomascus nasutus hainanus (Hainan black crested gibbon) survive on Hainan Island and around 26 individuals of the subspecies Nomascus nasutus nasutus (Cao Vit black crested gibbon) were rediscovered in 2002 in Trùng Khánh District, Cao Bằng Province, in northeast Vietnam, after last being seen in the 1960s.[2][3]
The Eastern black crested gibbon is the rarest and most critically endangered primate in the world. This status has resulted from deforestation of its habitat, encroachment, and poaching. It is considered to be one of "The World's 25 Most Endangered Primates."[4]
