Its closest living relatives among these appear to be the peculiar and nearly extinct Smith's dwarf chameleon from mountainous habitat, and especially the southern dwarf chameleon. The Karoo dwarf chameleon may actually be a subspecies of the latter; there appears to be significant gene flow between the two.

Semi-arid climate Semi-arid climate A semi-arid climate or steppe climate is the climate of a region that receives precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. A more precise definition is given by the Köppen climate classification, which treats steppe climates ("BSk" and "BSh") as intermediates between desert climates (BW) and humid climates in ecological characteristics and agricultural potential. Semi-arid climates tend to support short or scrubby vegetation and are usually dominated by either grasses or shrubs. To
