The Highveld (Afrikaans: Hoëveld, pronounced [ˈɦuəfælt], lit.'High Field') is the portion of the South African inland plateau which has an altitude above roughly 1500 m, but below 2100 m, thus excluding the Lesotho mountain regions to the south-east of the Highveld. It is home to some of the country's most important commercial farming areas, as well as its largest concentration of metropolitan centres, especially the Gauteng conurbation, which accommodates one-third of South Africa's population.

Location and description

The Highveld constitutes almost the whole of the

Kalahari desert to the west, the Bushveld to the north, the Mpumalanga Lowveld to the northeast, KwaZulu-Natal to the east, and the Lesotho Highlands, or Mountains, to the southeast.[3]
The Highveld covers an area of almost 400,000 km2 (150,000 sq mi), or roughly 30% of South Africa's land area.

The Highveld terrain is generally devoid of mountains, consisting of rolling plains, especially in the Free State, sometimes interrupted by rocky ridges such as the

Vredefort Dome. The Vaal River and its tributaries form the main water drainage system of the Highveld. Tributaries of the Orange River
drain the most southerly regions of the Highveld.

rainy season
occurs in summer, with substantial afternoon thunderstorms being typical occurrences in November, December, and January. Frost occurs in winter.

Urban areas and industry

Cities located on the Highveld include

Carletonville, and the cities of the West Rand and East Rand. The diamond-mining city of Kimberley
lies on the border of the Highveld and the southeastern Kalahari.

vegetables, occurring in irrigated areas and farmland closer to urban areas. The peat base of the grassland
acts as a natural filter, providing sources of clean water.

Flora

Naturally occurring vegetation in the Highveld consists of different types of well-established

savannah not dominating the ecosystem until more tropical latitudes. The major grass species are Hyparrhenia hirta and Sporobolus pyramidalis and among these are other grasses and herbs. Trees and shrubs never thrived due to the frequent fires that occurred in the dry season and the heavy grazing (once by wild animals and now by livestock
).

Fauna

The Highveld is home to a number of endangered animals, including

or sungazer (Smaug giganteus).

Threats and preservation

Like so many areas of grassland all over the world, the Highveld is excellent agricultural land and most of the area has been converted for farming. The grassland areas now remaining in the natural state are in various nature reserves, which, although a small portion of the Highveld, are still the largest areas of remaining grassland in South Africa. The protected areas include Suikerbosrand Nature Reserve,[6] Verloren Valei Nature Reserve, Nooitgedacht Dam Nature Reserve, Bronkhorstspruit Dam Nature Reserve, Vaal Dam Nature Reserve, and Koppies Dam Nature Reserves and Willem Pretorius Game Reserve.[7]
