The conservation effort of the javan langur (Trachypithecus auratus E. Geoffroy Saint-Hilaire, 1812) can be done effectively and efficiently if the animal needs are known. The objective of this study is to identify habitat characteristics preferred by javan langur at the homerange and microsite level. This study was carried out in Mount Merapi National Park (MMNP). Vegetation analysis at tree and pole stage was conducted on the available plots and on the used plots identified by search sampling method. Chi-square test was applied to
identify habitat selection. Logistic regression was applied to predict the variables affecting the probability of the javan langur presence. The result showed that the characteristic of habitat selected by the javan langur
in the level of home range are: site at 1500-2000 meter asl with more than 45% of slopes, high of tree basal area, abundant feeding trees and low human disturbances. Based on logistic regression analysis, the probability of javan langur presence increase with increasing tree basal area, number of feeding trees, altitude and distance from the disturbance. The probability of javan langur presence decreasing with increasing numbers of trees and distance from the river.
