Today, sheep thrive on the xerophytes, though each sheep requires about 4 ha of grazing to sustain itself.


Divisions

The Karoo is divided into the Great Karoo and the Little Karoo. The Little Karoo is delimited in the south by the Outeniqua–Langeberg Mountains that run east-west parallel to the coast, and in the north by the Swartberg Mountain Range that also runs east-west. The Great Karoo lies to the north the Swartberg.

The boundary to the east grades into the grasslands of the Eastern Midlands.Grassland biome. The Great Karoo is itself divided by the Great Escarpment into the Upper Karoo (generally above 1200–1500 m) and the Lower Karoo on the plains below at 700–800 m. A great many local names, each denoting different subregions of the Great Karoo, exist, some more widely, or more generally, known than others. In the Lower Karoo, going from west to east, they are the Tankwa Karoo, the Moordenaarskaroo, the Koup, the Vlakte, and the Camdeboo Plains. The Hantam, Kareeberge, Roggeveld, and uweveldare the better known subregions of the Upper Karoo, though most of it is simply known as the Upper Karoo, especially in the north.


Little Karoo

The Little Karoo’s boundaries are sharply defined by mountain ranges to the west, north, and south. The road between Uniondale and Willowmore is considered, by convention, to form the approximate arbitrary eastern extremity of the Little Karoo. Its extent is much smaller than that of the Great Karoo. Locally, it is usually called the ''Klein Karoo'', which is

Geography


Great Karoo

The Great Karoo straddles the 30° S parallel on the west of the continent, in a similar position to other semidesert areas on earth, north and south of the equator. It is furthermore in the rainfall shadow of the Cape Fold Mountains along the western coastline. The western "Lower Karoo" (the Tankwa Karoo and Moordenaarskaroo) contain remnants of the Cape Fold Mountains''Geological Map of South Africa, Lesotho and Swaziland''. (1970). Council for Geoscience, Geological Survey of South Africa.

Geological history of the Karoo Supergroup

The Karoo Supergroup was formed in a vast inland basin starting 320 million years ago, at a time when that part of Gondwana which would eventually become Africa, lay over the South Pole. Icebergs that had calved off the glaciers and ice sheets to the north deposited a 1 km-thick layer of mud containing

sills. This is solidified lava that was forced under high pressure between the horizontal strata of the sedimentary rocks that make up most of the Karoo’s geology. This occurred about 180 million years ago, when huge volumes of lava were extruded over most of Southern Africa and adjoining regions of Gondwana, both on the surface and deep below the surface between the sedimentary strata. Since this massive extrusion of lava, Southern Africa has undergone a prolonged period of erosion, exposing the older, softer rocks, except where they were protected by a cap of dolerite.

From about 150 million years ago the South African surface has been subjected to an almost uninterrupted period of erosion, particularly during the past 20 million years, shaving off many kilometers of sediments. This exposed the dolerite sills, which were more resistant to erosion than the Karoo sediments, forming one of the most characteristic features of the Karoo landscape, namely the flat topped hills, called "Karoo Koppies".


Geology of the Little Karoo

The geology of the Little Karoo bears no resemblance to that of the Great Karoo (see the diagram on the left, of a NS geological cross-section through the Little and Great Karoos).

The valley floor is covered, in the main, by the next (younger) layer of the Supergroup, namely the much softer Bokkeveld shales. The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was trapped in the valleys of the Cape Fold Mountains, especially during the

Accessed 2 May 2014 It incorporates nearly the whole of the historical and geographical Great Karoo, but also includes a portion of southern Namibia's Namaqualand, and South Africa's Bushmanland (both local geographical names, not names of biomes). It is the second-largest biome in South Africa, and forms the botanical transition between the Fynbos#Cape Floral Kingdom, fynbos biome to the south and the savannah biome to the north. It is defined primarily by the dominance of dwarf (less than 1 m high) shrubs with a co-dominance of grasses especially towards the north-east and east where it grades into the grassland biome of the highveld and the Eastern Midlands. The shrubs and grasses are deciduous, mainly in response to the irregular rainfall. Much of the Nama Karoo biome is used for sheep and goat farming, providing mutton, wool, and pelts for local and international markets, especially since livestock can frequently be provided with a regular supply of water from boreholes. Overgrazing exacerbates the erosion caused by the violent thunderstorms that occur, infrequently, in the summer. It also promotes the replacement of the grasses by shrubs, especially the less edible varieties such as the threethorn (''

(A pair of quagga was used to draw a horse carriage through London, more for curiosity than for any superiority the quagga might have had over a horse.) They were consequently also easy prey for hunters, who hunted them for sport rather than their meat. By the middle of the 1800s, they were almost extinct, and in 1883, the last one died in an Amsterdam zoo. Probably the strangest and most puzzling zoological phenomenon in the Great Karoo was the periodic, unpredictable appearance of massive springbok migrations. These migrations always came from the north, and could either go west towards Namaqualand and the sea, south-west through towns such as

, or south through the Camdeboo district. These vast herds moved steadily and inexorably across the plains, trampling all before them, including their own kind. Le Vaillant gave the first eyewitness account of such a migration in 1782. He rode through the herd filling the Plains of Camdeboo, seeing neither the beginning nor end of the moving mass. In 1849, a massive herd of springbok, amongst which were intermingled wildebeest, blesbok, quagga, and eland, moved through Beaufort West. Early one morning, the town was awakened to a sound like that of a strong wind, and suddenly the town was filled with animals. They devoured every sprig of foliage in the town and surrounding countryside. The last of the continuously moving herd left the town 3 days later, to disappear towards the west. The Karoo looked as if a fire had swept through it. During these migrations, the plains and hillsides on every side were thickly covered by one vast mass of springbok, packed like sheep in a fold. As far as the eye could see, the landscape was alive with them. During these migrations, the springbok never ran or trotted. On the whole, they were silent, except for the shudder of their stamping hoofs. Nothing could divert them, and hunters could ride amongst them, shooting them at random, without apparently causing alarm. People could move amongst them and kill them with sticks, or cripple them by seizing a leg and breaking it. Not only people followed these herds for the easy meat they provided, but also

(2006) Population structuring in mountain zebra (''Equus zebra''):the molecular consequences of divergent histories. ''Conservation Genetics''. The two species are, therefore, rarely seen in the same habitat. The quagga is closely related to Burchell's zebra, and appears also to have been confined to the plains.

Thus, they were endemic to, amongst others, the western Lower Karoo and the Little Karoo. However, they were hunted to near extinction, leaving fewer than 100 individuals by the 1930s. Conservation efforts since then brought their numbers up to 1200 by 1998, mainly by concentrating these zebra in nature reserves and protected areas, the most well-known of these being the

district was apparently the first person to demonstrate that the ostrich could successfully be domesticated, bred in captivity, and the eggs hatched in incubators, while still producing the magnificent feathers. This idea was quickly adopted by farmers in the Little Karoo, where they started growing lucerne as the birds' favorite food. During 1880, no less than 74,000 kg of feathers were exported, and in 1904, it passed the 210,000-kg mark. The First World War brought about a slump in the ostrich feather market, but the industry recovered in later years, when not only the feathers were sought after, but also ostrich leather, and its meat, which is very tasty, and a major export item. Today, several farms can be visited by tourists, near Oudtshoorn, the center of the ostrich industry.

Like the Karoo Koppie, the multibladed windpump became an iconic feature of the Great Karoo.
