SURVEY OF THE LONG-TAILED MACAQUES INTRODUCED ONTO TINJIL ISLAND, INDONESIA

From February 1988 though June 1990, 475 adult long-tailed macaques (M acaca fascicularis) were released on Tinjil Island to establish a bree ding program that will provide monkeys for biomedical research while c ontributing to Indonesia's primate conservation efforts. A survey was conducted during the summer of 1990 to assess the status of the island 's population. Basic demographic data were consistent with those from other field studies of long-tailed macaques, and estimates of reproduc tivity suggest a successful breeding program. The facility established on Tinjil Island should serve as a useful model for future primate re source and conservation programs. (C) 1993 Wiley-Liss, Inc.
