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
Kazakh semi-desert encroachment are the main threats to this ecoregion's integrity, and its conservation status is listed as "critical/endangered". However, recent and dramatic reductions in the number of livestock in Kazakhstan have resulted in large areas having a greater chance for rehabilitation. No areas in this ecoregion are strictly protected, and some refuges do not adequately preserve local ecosystems. Kazakh semi-desert The Kazakh semi-desert is an ecoregion in the deserts and xeric shrublands biome, located in Kazakhstan. The climate is semi-arid and continental, with a total annual precipitation of , and mean temperatures in January averaging and in July . It is
