PRELIMINARY-REPORT ON PRESBYTIS-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 pro bably numbers less than or equal to 400 animals (Wu, 1983; Jiang et al , 1991). Our preliminary study 15 km from the Vietnamese border docume nts 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 m acaques. While the study site is contiguous with a provincial park and P. francoisi are under protective legislation, development of this ar ea for tourism and occasional local hunting has consequences for conse rvation policy.
