Abstract:

A survey on winter habitat selection of rhesus macaques (Macaca mulatta tcheliensis) was carried out from November 2007 to February 2008 in Taihang Mountains (35°11′N,112°16′E ) in Jiyuan, Henan Province, China. 180 plots of 10 m × 10 m were set up and 10 factors were selected to analyze the habitat selection of the macaque. These factors include slope terrain, altitude of the plot, slope position, slope face, slope degree, the distance from water resource, concealment, human disturbance, canopy, and average DBH (diameter breast height). The results showed that, for their activities, the macaque usually chose a certain habitat with characteristics as follows:1)the average tree whose DBH is over 15 cm;2) the distance from human disturbance is less than 2 000 m;3) the distance to water is less than 1 000 m; 4) the gradient of slope ranges from 15° to 40°;5)the altitude of the monkey ranging sites ranged from 1 000 m to 1 300 m;6) the canopy cover was less than 60%. In addition, the macaques preferred south-faced and southwest-faced slopes in winter. The principal component analysis indicated that these five factors will contribute 70.713% of the total variance, while the others might have less impact on habitat selection.
