Karoo are exposed. These are locally known as the Cango Group, but are probably continuous with the Malmesbury Group that forms the base of Table Mountain on the Cape Peninsula, and similar outcrops in the Western Cape. In the Little Karoo, the outcrop is composed of limestone, into which an underground stream has carved the impressively extensive Cango Caves. The Great Karoo and Little Karoo lie almost entirely within two of South Africa’s eight botanical biomes, namely the Succulent Karoo biome and the Nama Karoo biome, both of which, like the Karoo Geological System, are more extensive than the geographical or
Namaqua National Park km². The park is semi-desert, with hot and dry summers and cold winters with variable, generally sparse rainfall. Most precipitation occurs between May and August. The eastern part of the park receives more rainfall than the west. The park is located in Namaqualand, which lies within the Succulent Karoo. Namaqualand has an area covering 55,000 hectares, located in the northwest corner of Northern Cape Province. The park is part of the semi-desert Succulent Karoo biome, one of the most unusual biomes in the world. This biome is a biodiversity hotspot with the greatest biodiversity and the highest concentration of succulent
