The present study was conducted to elaborate the role of altitude and aspect on community structure and species distribution in different seasons during 2018-2019.   Field survey was carried out during two seasons’ spring and summer. A total of 63 species belonging to 51 families were recorded during spring season, while 74 species belonging to 53 families were reported during summer season. However, PCORD software version 5 was used to classify the vegetation of the area, TWINSPAN classified the vegetation of the entire area into three associations in spring, while 6 associations in summer season. Altitude and aspect were two main factors to describe the distribution of vegetation of research area. Over grazing, soil erosion and over exploitation were found to be main ecological factors, which disturbed local vegetation. This paper enumerates the local uses of 68 plants species belonging to 28 families, which are used by local people for various purposes. Rosaceae was the leading family (11 spp.) followed by Asteraceae (10 spp.) and Silaceae (4 spp.), while the rest have less than 4 species. Out 68 plants 3(26.57%) are used as medicinal, 26(18.18%) as fuel, 25(17.48%) as fodder, 14 (9.79%) as a fruit, 11(7.69%) as timbers, 9 (6.29%) as Thatching and vegetable, 5 (3.49%) ornamental, (2.79%) as food and 1(0.69%) as broom and cosmetic. 38 ethno medicinal species were used to cure 33 different diseases in the studied area. These plants were used to treat various ailments: among 38 ethno medicinal plant species 6 species (8%) were used as analgesic, 5 species of 7% as anthtmentic, 4 species of 5% as antibilous and antidiarrheal, 3 species of 4% as diuretic and jaundice.
