Range Description

This species is found in a small area of northeastern Viet Nam and southeastern China, northeast of the Red River, where it is restricted to the Phong Nam-Ngoc Khe Mountains, Trung Khanh District, northern Cao Bang province, and adjacent forest in Jingxi County, Guangxi (Geissmann et al. 2002, 2003b; W. Bleisch pers. comm.). It is possibly still extant in neighbouring Hoa Binh province, Viet Nam, as well, and in 2002 it was additionally reported from Kim Hy forest in Bac Kan province (which has since been proposed as a nature reserve). The range seems to have formerly extended from Ha Long Bay south to the Red River delta; gibbons of some species formerly lived in adjacent areas of southeastern China (Guangdong and Guangxi provinces), but are thought to have almost completely disappeared from there during the 1950s (Geissman et al. 2000; Fellowes et al. 2003). It is possible that some individuals still remain in isolated pockets of inaccessible karst forest.
