Karoo korhaan Karoo korhaan The karoo korhaan ("Eupodotis vigorsii"), also known as karoo bustard, is a species of bird in the bustard family, Otididae, from Southern Africa. The species is sometimes placed in the genus "Heterotetrax". It is the sister-species to Rüppell's korhaan, and the two species are sometimes considered conspecific (the same species). There are two subspecies, the nominate race, from south-eastern South Africa, and "E. v. namaqua" (Roberts, 1932), from north-eastern South Africa and southern Namibia. The karoo korhaan lives in a range of arid habitats associated with the karoo and other arid scrubland habitats found in eastern South Africa
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
