Habitat destruction includes forest transformation and illegal logging and is the main factor for population decrease. The aims of this research were to evaluate the habitat conditions concerning group size, ratio of male to female, population density, vegetation stratum utilization and vegetation that has been frequently visited by monkeys; interaction between human population, Bange and forest; and craniometry of Bange. Methods used were line transect for population, diagram of habitat profile, Instantaneous sampling for food resources, interview for interaction between human population and forest and craniometry measurement for skull. Results showed that the population size was 39,82 individuals, density was 0,71 individuals/km2, ratio of male to female was 1:1,65. They used stratum B frequently (62,5%). Result of interview showed that agricultural disturbiance were caused by wild rats (44,80%), monkeys (29,90%) and wild pig s (22,30%). Total variability of skull size was 70,7% or higher than total variability of skull is length jowbone to the equal shape 0,498. Eigen vector value of each size and shape were 102,89 and 35,45. Cranial size of males Bange reality bigger than is female, but the have the same form.
