Abstract: An Inventory of plant species of Dureji game reserve was prepared on the basis of field trips conducted in different parts of the year particularly in winter, summer and monsoon. A total of 79 plants species were collected belonging to 66 genera under 32 families. Three rare species were found from the study area. Phenological status of each species i.e. flowering and fruiting condition was also observed. Quantitative analysis on species diversity in addition to phytosociological attributes analysis was conducted. Some ecological parameters such as lifeforms, density, relative density, cover, relative cover frequency and relative frequency were investigated. Vegetation cover varies from place to place depending upon the texture and structure of the soil. Vegetation structure and density is greatly influenced by the rainfall. One of the main threats to the vegetation of the study area is grazing. The current work provides floristic and ecological data for these threatened habitats of Dureji Game Reserve and documents the structure and composition of vegetation.
