Karoo Supergroup Malawi, as well as on other continents that were part of Gondwana. The basins in which it was deposited formed during the formation and breakup of Pangea. The type area of the Karoo Supergroup is the Great Karoo in South Africa, where the most extensive outcrops of the sequence are exposed. Its strata which consist mostly of shales and sandstones, record an almost continuous sequence of marine glacial to terrestrial deposition from the Late Carboniferous to the Early Jurassic. These accumulated in a retroarc foreland basin called the "main Karoo" Basin. This basin was formed by the subduction and orogenesis
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.
