Karoo Karoo The Karoo ( ; from a Khoikhoi word, possibly "garo" "desert") is a semi desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the
Namaqua National Park km². The park is semi-desert, with hot and dry summers and cold winters with variable, generally sparse rainfall. Most precipitation occurs between May and August. The eastern part of the park receives more rainfall than the west. The park is located in Namaqualand, which lies within the Succulent Karoo. Namaqualand has an area covering 55,000 hectares, located in the northwest corner of Northern Cape Province. The park is part of the semi-desert Succulent Karoo biome, one of the most unusual biomes in the world. This biome is a biodiversity hotspot with the greatest biodiversity and the highest concentration of succulent
