Almost 99% of the region is bare ground or sparse vegetation that is dependent on uncertain rainfall. The grasses are typically canegrass ("Eragrostis"), needlegrasses ("Aristida"), and species of genus "Stipagrostis". The herbs include ("Tribulus"), ("Heliotropium"), and ("Pulicaria"). Characteristic tree species are the umbrella thorn acacia ("Acacia tortilis"), salam ("Acacia ehrenbergiana"), Egyptian balsam ("Balanites aegyptiaca"), and ("Maerua crassifolia"). Along the southern edge are steppes featuring clumps of bunchgrass ("Panicum turgidum").
