Succulent Karoo Succulent Karoo The Succulent Karoo is a desert ecoregion of South Africa and Namibia. The Succulent Karoo stretches along the coastal strip of southwestern Namibia and South Africa's Northern Cape Province, where the cold Benguela Current offshore creates frequent fogs. The ecoregion extends inland into the uplands of South Africa's Western Cape Province. It is bounded on the south by the Mediterranean climate fynbos, on the east by the Nama Karoo, which has more extreme temperatures and variable rainfall, and on the north by the Namib Desert. The Succulent Karoo is notable for the world's richest flora of succulent plants,
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
