The East Sudanian Savanna is a hot, dry, tropical savanna ecoregion of Central and East Africa.
This is the eastern half of the broad savanna belt which runs east and west across Africa, this section lying east of the Cameroon Highlands. The Sahel belt of drier acacia savanna lies to the north and beyond that is the Sahara Desert, while to the south lies the humid forests of the DR Congo.
The Sudd flooded grasslands of southern Sudan divide this area into eastern and western blocks. The land is mainly flat, although there are some hillier sections around Lake Albert and in Western Ethiopia.
The Sudanian Savanna is a broad belt of tropical savanna that runs east and west across the African continent, from the Atlantic Ocean in the west to the Ethiopian Highlands in the east. The Sahel, a belt of drier grasslands and acacia savannas, lies to the north, between the Sudanian Savanna and the Sahara Desert. To the south the forest-savanna mosaic is a transition zone between the Sudanian Savanna and the Guinean moist forests and Congolian forests that lie nearer the equator.
The World Wide Fund for Nature divides the Sudanian Savanna into two ecoregions, separated by the Cameroon Highlands. The West Sudanian Savanna runs from the Atlantic Ocean to eastern Nigeria, and the East Sudanian Savanna runs from the Cameroon Highlands east to the Ethiopian Highlands.
The Sudanian Savanna is one of the three distinct physiographic provinces of the larger African Massive division. Physiography divides this province into three distinct physiographic sections, the Niger Basin, the Lake Chad Basin, and the Middle Nile Basin.
