natural region in southern Africa, at an elevation of about 2,500–4,000 feet (800–1,200 metres). Centred in Limpopo province, South Africa, it extends into northern KwaZulu-Natal province, Swaziland, Mozambique, Zimbabwe, and Botswana. The bushveld (“thornbush field”) is characterized by trees—acacia and baobab as well as thornbushes—and tall grasses. It is moderately dry, with annual rainfall of about 15–25 inches (380–640 mm). Herding is the principal economic activity; large-scale cultivation is possible only in irrigated areas.
