Construction of a hydropower project on the Kihansi river in Southern Tanzania will substantially alter the river's flow. On the basis of both qualitative and quantitative botanical surveys, forest in the Kihansi gorge below the dam site was found to be mostly typical species and endemic-rich Eastern Arc forest. An unusual forest type, dominated almost entirely by Filicium decipiens was also present. Eastern Arc forests are of both global and national importance for biodiversity conservation, and measures to mitigate impact of the dam on the forest are suggested. Further environmental monitoring is recommended in order to evaluate the choice of mitigation measures.
