The region has a flat topography and a hot, tropical climate. Annual rainfall is recorded between 200mm in the north and 600 mm in the south from May to September. Vegetation is dominated by vast expanses of grasslands interspersed with acacia tree species. Most of the region’s fauna is either threatened or extinct and includes lion, Dorcas gazelle, scimitar-horned oryx, dama gazelle, red-fronted gazelle, and cheetah. The area's wildlife is threatened by poaching while the ecoregion’s integrity is compromised by overgrazing, fires, wood collection and increasing desertification.
