    Forests, trees and woodlands cover almost one-third of the Earth’s land area. They are a crucial source of food and income for more than a billion people around the globe. They provide a variety of wood and non-wood products and vital ecosystem services – preventing erosion from wind and water, preserving water quality, shading crops and livestock, absorbing carbon which contributes to countering climate change, and providing habitat for many species of plants and animals, thus helping to conserve the planet’s biological diversity.

    This study attempted to predict the likely impacts of a dam reservoir and flow regulation on riparian plant composition and diversity. The study was conducted around the Koga dam in the upper part of the Blue Nile basin in the northwestern part of Ethiopia. Floristic composition and diversity in the riverine and adjacent sites of the river was studied. The presence of plant species that would be affected by the storage of the Koga River water and the modification of the downstream river flow regime were assessed.
