River ecosystem supports a large number of plant and animal species comparing to other ecosystems (Ward, J. et.al. 1999). River biodiversity consist of aquatic and terrestrial components which varies along the distance of river and its dynamics. Rivers stretch passing along the urban centres are subject to various pressures including point and non-point pollution, water extraction, sand mining, invasive species, loss of riparian flora due to anthropogenic pressure and other physical alterations. Present study is conducted to understand biodiversity of the river stretch of the Haora river along Agartala city for about 2-kilometer stretch. The Primary objective for this study is to evaluate the biodiversity of the river and riparian zone at its current state. Data is compiled and interpreted to understand the possible improvement in biodiversity of river area after interventions like cleaning, landscaping, plantation etc. Quadrate and transect method were used for assessment of flora and fauna of the locations. Studies have revealed 28 species of plants and 36 species of birds. The study also reveals that the river stretch is highly modified with anthropogenic activities. Interventions like shore line cleaning, plantation, preventing pollution will enhance good biodiversity.
