The present study was carried out in Himachal Pradesh of the Western Himalayas, India to obtain information on the wild edible plants used by the migratory shepherds. The shepherds started their migration in July from Chitkul, Rakchham, Batseri, Sangla and Kamru of district Kinnaur (Himachal Pradesh). Questionnaire for the survey, personal field visits and participatory observations were used to collect information about the use of various plants by the migratory shepherds. The shepherds move in a group of 5 to 6 comprising their own family members and size of the flock (of sheep and goats) varied from 654 to 990. The migration route followed from their villages to Churdhar ranges (mid hills) and to Sirmour ranges (low hills). It was observed that in all 50 species were used by shepherds enroute from high hills to low hills. In high hills, 23 species, in mid hills 31 species and in low hills 34 species were found to be used as livelihood source. Some of the plants, besides being used as fruits and vegetables, are also used as herbal tea (bark of Betula utilis) and condiments. Morchella esculenta was found to be one of the delicacies used for food in their tribe. The documentation of plant resources and the indigenous knowledge of shepherds highlighted in the present study is a step in raising awareness about the importance of these edible plants and their further conservation.

This study was carried out to assess the tree species diversity and distribution in Pasighat town of Arunachal Pradesh. Trees are important component of vegetation because of their economic value to mankind. There is high pressure on forest estates due to high demand on forest economic resources as a result of geometric increase of human population in the region. The results of the study showed that a total of 103 tree species representing 85 genera and belonging to 45 families were recorded from the study area. Fabaceae with 19 species was the dominant family of tree species. Co-dominant families were Rutaceae, Meliaceae, Anacardiaceae, Arecaceae, Moraceae, Myrtaceae, Lauraceae, Euphorbiaceae and Sapotaceae. The structural pattern showed a heterogeneous distribution of trees which is the chief character of forests of Eastern Himalaya. The area is rich with diverse plant species and by obtaining proper information about it, prime efforts can be made to conserve it.

Corbett Landscape and Corbett Tiger Reserve is a beautiful place of roar and trumpets. Tiger is a very intelligent animal and are able to survive in any situation. In dry summer season the fulfillments of vital need become tight and tough for all. Especially prey species aggregates near water bodies. On the other hand tiger is territorial animal. Dry season depicts extra efforts to catch the prey by tiger. Different dynamics of Predator-prey relationship is recorded in this season. Total 8 cases of elephant's mortality with tiger attack sign were ceased. Total 120 scats were analyzed. Scat analysis resulted less daily requirement of tiger. Ecological requirements are 4-5 kg per day. But scat analysis resulted very less in rest of proper daily consumption. Mostly attacks on elephant recorded in the month of June or in dry season. Such type of tough situation the tiger movement become in human-dominated landscape for easy prey (Livestock predation). The chances of conflicts are more and more in these periods. Increasing rate of conflicts is always die heart for tiger as well as human beings.

In dry summer season, the chances of food availability become tough and hard. Prey species moves towards water resources. But tiger have a good and ample quality to survive anywhere with its intelligence and adaptability for survival with environment. To detect the food and feeding behaviour of tiger in this dry month, we had collected the tiger scat for scat analysis. Scat analysis is techniques by which we can reconstruct the tiger's diet with the help of undigested remain on which tiger had prayed. This is an indirect method to know the tiger's food and feeding behaviour, choice of food, availability of preys in dry season etc. Interspecific as well as Intraspecific struggle affects biomass consumption (daily diet & annual diet profile) of tiger and other sympatric species like Leopard in area.
