The main aim in this study was to assess the subsistence needs of the local human population and the conservation needs of key wildlife species. The hypotheses under test were that the local human populations have to depend on wildlife resources for their livelihood in the absence of other suitable subsistence options, and thus may compete adversely with the ecological needs of wildlife species sharing the same habitat. As a generalist feeder, Phayre's langurs used a total of 81 plant species in their annual diet, although only 16 of these accounted for more than 75% of total feeding time. They were folivorous, but switched to fruits and seeds diet whenever needed, either due to scarcity in foliage availability, or due to their specific preference for energy rich other dietary sources. Their group size and structure, behaviour, and ranging pattern matched other small bodied langurs in the region, and were in prefect harmony with the prevailing habitat condition. Capped and golden langur groups used 44 and 53 plant species, respectively in their annual diet, and top ten species accounted for more than 55% of the total feeding time. During successive years after jhooming there was an increase in both the number of tree species and in the number of trees in fallows. Of the total 52 regenerating tree species, 26 (50%), 14 (27%), and 16 (31%) were also the food species for Phayre's capped and golden langurs, respectively. A total of 11 (21.2%) species of these were also used by the local people for their various needs. On average, 71% of total income of all the villagers surrounding the study area came from sanctuary-dependent sources also used by three primate groups. The people were aware, though, of the negative impacts of their activities on the wildlife resources inside the study area, but their requirements for these resources took precedence over the negative impacts.
