Preliminary report onPresbytis francoisi leucocephalus

There is no long-term study on the white-headed leaf-eating monkey in Hua Shan, Guangxi Zhuang Autonomous Region, China. This subspecies probably numbers ≤400 animals (Wu, 1983; Jiang et al., 1991). Our preliminary study 15 km from the Vietnamese border documents group size and composition and habitat use based on 450 contact h. The study group may interact with the white-sideburned (white-cheeked or black) subspecies of Presbytis francoisi,and shares habitat with macaques. While the study site is contiguous with a provincial park and P. francoisiare under protective legislation, development of this area for tourism and occasional local hunting has consequences for conservation policy.
