Overview
High points in this woreda include Mount Fota (3235 meters). Rivers include the Berga, the main tributary of the upper Awash River. The vegetation of the Berga flood-plain, a part of the vast plains on the Central plateau of Shewa, includes grasses, sedges and other plants peculiar to the area, which include species from the genera Haplocarpha, Ranunculus, Cyperus, and Pennisetum and Andropogon. Although coffee is an important cash crop of this woreda, less than 20 square kilometers are planted with this crop.
