It consists of a red granite mountain range projecting from a flatter area and is of importance for both plant and animal life.
[1] The plains have deep sandy-loam soils and the dominant plant is Haloxylon salicornicum, with the desert gourd being common and Asphodelus tenuifolius occurring in depressions.
On the thin slopes below the rocks, Acacia gerrardii is dominant and is accompanied by other woody shrubs such as Searsia, Periploca, Gymnocarpos and Ephedra foliata.
In the wadis and runnels, more Acacia gerrardi grows, associated with Lycium shawii, Pulicaria undulata, Ochradenus baccatus and Zilla spinosa.
