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
Karoo the mountains, but are very secretive, so are rarely seen. Many of the animals that formerly inhabited the Karoo in large numbers, including lions, have been reintroduced to the area in nature reserves and game farms. As in the Great Karoo, antelope and other big game inhabited the Little Karoo in the past. However, the dominant zebra was not the quagga, but the Cape mountain zebra, ("Equus zebra zebra") which is adapted for life on rugged, mountainous terrain. Their hooves are harder and faster-growing than those of Burchell’s zebra ("Equus quagga burchellii"), which lives on the plains. The two species
