Robertson Karoo Robertson Karoo Robertson Karoo is a semi-arid vegetation type, restricted to sections of the Breede River Valley, Western Cape Province, South Africa. It is a subtype of Succulent Karoo (geographically an extension of the "Little Karoo") and is characterised by the dominance of succulent plant species, and by several endemic plants and animals. This vegetation type occurs in several large patches within the Breede River Valley, in the Western Cape Province of South Africa. It occurs in the area between Worcester in the north-west, Ashton in the east, and the Riviersonderend mountains in the south. Robertson Karoo typically consists of
Karoo desert ephemerals, spaced 50 cm or more apart, and becoming very sparse going northwards into Bushmanland and, from there, into the Kalahari Desert. The driest region of the Karoo, however, is its southwestern corner, between the Great Escarpment and the Cederberg-Skurweberg mountain ranges, called the Tankwa Karoo, which receives only 75 mm of rain annually. The eastern and north-eastern Karoo are often covered by large patches of grassland. The typical Karoo vegetation used to support large game, sometimes in vast herds. Today, sheep thrive on the xerophytes, though each sheep requires about 4 ha of grazing to sustain itself. The
