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

This is the largest forest in the country, a semi-arid surrounded by semi-desert, with four dominant species: "Juniperus procera", "Olea africana", "Buxus hildebrantii", and "Tarchonanthus camphoratus". Elevations play a major factor in temperature, with the escarpments and plateaus on average 11°C (52°F) cooler, day or night. The climate of the coastal strip is influenced by warm ocean waters, keeping the
