Vietnam Primate Conservation Status Review Part 2: LEAF MONKEYS 34 3.1.3 Distribution The range of T. francoisi is limited to southern China and northern Vietnam. It is the most widespread species of the francoisi group. The northernmost part of its range is about 28 O N latitude in Guizhou Province, China, and its southernmost extent is about 21 O 30’N latitude in Lang Son Province, Vietnam. Distribution in China Francois’ langur is widely distributed throughout southern China but its range is highly fragmented (Zhang et al., 1992). It occurs in more than twenty counties in western Guangxi Province and in four counties in southwestern Guizhou Province. Isolated fragments are found in three counties of northeast Guizhou Province. According to recent surveys the population in China totals 3,200-3,500 individuals. The species occurs in 16 reserves with a total of 1,900-2,000 individuals (Wang Yingxiang et al., 1998). Distribution in Vietnam The historical range of T. francoisi in Vietnam may include the provinces of Ha Giang, Cao Bang, Lang Son, Bac Kan, Thai Nguyen, Tuyen Quang and the eastern parts of Lao Cai and Yen Bai. However, it seems to have been extirpated from most of its original distribution and can now only be found in isolated forest fragments. 3.1.4 Francois’ langur records in Vietnam Du Gia Nature Reserve (HA GIANG) Special use forest: Nature reserve Francois’ langur status: Provisional occurrence, last report in 2001 (interview, hair sample), (Le Khac Quyet, 2001) The provisional occurrence of this species in this locality is based on interview data collected in December 2000 to January 2001 during a FFI survey. A hair sample was also found in Lung Dam Village, Du Gia Commune, Yen Minh District (within the Nature reserve). The hair came from an animal shot in September 1999 (Le Khac Quyet, 2001). Although this recent data represents a new distribution record for the species, the record is within the species range stipulated by Fooden (1996) and the limestone forest of Du Gia Nature Reserve provides suitable habitat for the species. Local informants suggest 4-6 groups, each consisting of 3-7 individuals occur in the nature reserve. Further surveys are required to confirm the occurrence of the species in this area. Cham Chu proposed Nature Reserve (TUYEN QUANG) Special use forest: Proposed nature reserve Francois’ langur status: Provisional occurrence, last report in 2001 (interview)(Long & Le Khac Quyet, 2001) Francois’ langurs are reported without reference in Chiem Hoa District, Tuyen Quang Province (Ministry of Science, Techonology and Environment, 1992). Two surveys conducted in the area (Ratajszczak et al., 1992; Dang Ngoc Can & Nguyen Truong Son, 1999) did not report this occurrence. A live animal was found in Nam Luong Village, Ham Yen District, however. It was bought from a villager in Khuon
