Karoo Karoo biome. The number of mainly succulent plant species is very high for an arid area of this size anywhere in the world. The Nama Karoo biome is located entirely on the central plateau mostly at altitudes between 1000 and 1500 m. 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 biome to the south and the savannah biome to
Karoo as "Karoo". However, it has a major extension inland into the Tankwa Karoo and Moordenaarskaroo regions of the Lower Karoo, and adjoining Upper Karoo region of the geographic Great Karoo. It also occurs to the south, in part of the Breede River Valley, as the Robertson Karoo. From here, it continues eastwards into the western half of the Little Karoo. The Succulent Karoo biome is dominated by dwarf, leafy-succulent shrubs, and annuals, predominantly Asteraceae, popularly known as Namaqualand daisies, which put on spectacular flower displays covering vast stretches of the landscape in the southern spring-time (August–September) after good rains in
