South Saharan steppe and woodlands
From Wikipedia, the free encyclopedia
The South Saharan steppe and woodlands is a deserts and xeric shrublands ecoregion of northern Africa.
The ecoregion covers 1,101,700 square kilometers (425,400 square miles) in Algeria, Chad, Mali, Mauritania, and Sudan. It extends east and west across the continent in a band, forming a transition between the hyper-arid Sahara Desert to the north and the Sahel grasslands and savannas to the south.
Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm, but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses.[1]
