In the late nineteenth century, about 30% of Ethiopia was covered with forest. The clearing of land for agricultural use and the cutting of trees for fuel gradually changed the scene, and today forest areas have dwindled to less than 4% of Ethiopia's total land. The northern parts of the highlands are almost devoid of trees. However, about 45,000 square kilometres of dense forest exist in the southern and southwestern sections of the highlands. Some of these include coniferous forests, found at elevations above l,600 meters, but a majority of the forestland consists primarily of woodlands found in drier areas of the highlands and in the drier areas bordering the highlands.
