Its habitat is Karoo and desert scrub in the south, extending to the escarpment zone in the north. The first formal description of the Karoo chat was by the Swedish naturalist Johan August Wahlberg in 1855 under the binomial name "Erithacus schlegelii". The species was subsequently placed in the genus "Cercomela" introduced by Charles Lucien Bonaparte in 1856. It was moved to its current genus, "Emarginata",

This massive lava outpouring brought the Karoo sedimention to an abrupt end. The name Drakensberg group is derived from the fact that this layer forms the uppermost 1400 m of the Great Escarpment on the international border between Lesotho and KwaZulu-Natal, often referred to as "the" Drakensberg (although technically the "Drakensberg" refers to the entire 1000 km
