The supergroup consists of a sequence of units, mostly of nonmarine origin, deposited between the Late Carboniferous and Early Jurassic, a period of about 120 million years. In southern Africa, rocks of the Karoo Supergroup cover almost two thirds of the present land surface, including all of Lesotho, almost the whole of Free State, and large parts of the Eastern Cape, Northern Cape, Mpumalanga and KwaZulu-Natal Provinces of South Africa.

This is the largest forest in the country, a semi-arid surrounded by semi-desert, with four dominant species: "Juniperus procera", "Olea africana", "Buxus hildebrantii", and "Tarchonanthus camphoratus". Elevations play a major factor in temperature, with the escarpments and plateaus on average 11°C (52°F) cooler, day or night. The climate of the coastal strip is influenced by warm ocean waters, keeping the
