The results showed that in the winter season the most preferred habitat of the langurs was the moist temperate coniferous forests interspersed with deciduous trees, while in the summer season they preferred to migrate into the subalpine scrub forests at higher altitudes. Langurs were folivorous in feeding habit, recorded as consuming more than 49 plant species （27 in summer and 22 in winter） in the study area. The mature leaves （36.12%） were preferred over the young leaves （27.27%） while other food components comprised of fruits （17.00%）, roots （9.45%）, barks （6.69%）, flowers （2.19%） and stems （1.28%） of various plant species.展开更多
