Some of the rich coffee-growing regions of Ethiopia are found on these soils. At a global scale, water erosion is the main cause off soil degradation (Deniz et al. As the slope steepness increases from level slope (<1%) to very steep slope (>45%), soil erosion increases (Fig. There are a few Ethiopian wolves. slopes are often steep, and lithosols (shallow soils consisting of imperfectly weathered rock fragments) abound, accounting for another 10 percent of the continents surface. /XHeight 519 a mangrove forest, reeds or sedges).

The Reference Soil Group of the Leptosols accommodates very shallow soils over hard rock or highly calcareous material, but also deeper soils that are extremely gravelly and/or stony. More-abundant varieties found in the lowlands include such antelopes as the oryx, the greater kudu, and the waterbuck, various types of monkeys including the black-and-white colobus (known as guereza in Ethiopia and hunted for its beautiful long-haired pelt), and varieties of wild pig. According to the assessment and documentation report of Bekele et al.

The other types of soils are shallow Andosols, Lithosols, and Haplic Phaeozems that are mainly common in the area between 2,500 and 3,500 m. The Simien Mountains are highly eroded as a result of human land use practices and as a result of the topography . The result also reveals that most of the watershed erosion severity evaluated under very low and low soil erosion severity classes covering 97.3% of the watershed areas which is due to the effect of mixed plantation of various tree and terraces. 0 0 0 0 0 0 278]>> Moderate soil loss was estimated from pellic vertisols followed by Lithosols.
