Драконовы горы: Горный хребет Южной Африки

Mountain range in South Africa

The Drakensberg (Zulu: uKhahlamba, Sotho: Maloti, Afrikaans: Drakensberge) is the eastern portion of the Great Escarpment, which encloses the central Southern African plateau. The Great Escarpment reaches its greatest elevation – within the border region of South Africa and Lesotho. The Drakensberg escarpment stretches for more than from the Eastern Cape Province in the South, then successively forms, in order from south to north, the border between Lesotho and the Eastern Cape and the border between Lesotho and KwaZulu Natal Province. Thereafter it forms the border between KwaZulu Natal and the Free State, and next as the border between KwaZulu Natal and Mpumalanga Province. The escarpment winds north from there, through Mpumalanga, where it includes features such as the Blyde River Canyon, Three Rondavels, and God's Window. It then extends farther north to Hoedspruit in southeastern Limpopo where it is known as 'Klein Drakensberg' by the Afrikaner. From Hoedspruit it extends west to Tzaneen, also in Limpopo Province, where it is known as the Wolkberg Mountains and Iron Crown Mountain. At above sea level, the Wolkberg is the highest elevation in Limpopo. The escarpment extends west again and at Mokopane it is known as the Strydpoort Mountains.

The Afrikaans name Drakensberge comes from the name the earliest Dutch settlers gave to the escarpment, namely Drakensbergen, or Dragons' Mountains. The highest portion of the Great Escarpment is known in Zulu as uKhahlamba and as Maloti in Sotho ("Barrier of up pointed spears").

The Great Escarpment is composed of steep rift valley walls formed around a bulging of continental crust during the breakup of southern Gondwana that have since eroded inland from their original positions near the southern African coast, and its entire eastern portion (see the accompanying map) constitutes the Drakensberg. The Drakensberg terminate in the north near Tzaneen at about the 22° S parallel. The absence of the Great Escarpment for approximately to the north of Tzaneen (to reappear on the border between Zimbabwe and Mozambique in the Chimanimani Mountains) is due to a failed westerly branch of the main rift that caused Antarctica to start drifting away from southern Africa during the breakup of Gondwana about 150 million years ago. The lower Limpopo River and Save River drain into the Indian Ocean through what remains of this relict incipient rift valley, which now forms part of the South African Lowveld. Knight and Grab mapped out the distribution of lightning strikes in the Drakensburg and discovered that lightning significantly controls the evolution of the mountain landscapes because it helps to shape the summit areas – the highest areas – with this blasting effect. Previously, angular debris was presumed to have been created by changes typical of cold, periglacial environments, such as fracturing due to frost.

The geological composition of Drakensberg (escarpment wall) varies considerably along its more than 1000 km length. The Limpopo and Mpumalanga Drakensberg are capped by an erosion resistant quartzite layer that is part of the Transvaal Supergroup, which also forms the Magaliesberg to the north and northwest of Pretoria. The portion of the Drakensberg that forms the KwaZulu Natal – Free State border is formed by slightly younger Beaufort rocks (250 million years old) that also are part of the Karoo Supergroup. The Ecca and Beaufort groups are composed of sedimentary rocks that are less erosion resistant than the other rocks that make up the Drakensberg escarpment. Therefore, this portion of escarpment is not so impressive as the Mpumalanga and Lesotho stretches of the Drakensberg. The Drakensberg that form the northeastern and eastern borders of Lesotho, as well as the Eastern Cape Drakensberg, are composed of a thick layer of basalt (lava) that erupted 180 million years ago. The climate is wet and cool at the high elevations, which experience snowfall in winter. The grassy lower slopes (from ) of the Drakensberg in Eswatini, South Africa and Lesotho constitute the Drakensberg montane grasslands, woodlands, and forests ecoregion.

The mountains are rich in plant life, including a large number of species listed in the Red Data Book of threatened plants, with 119 species listed as globally endangered and "of the 2 153 plant species in the park, a remarkable 98 are endemic or near endemic". One bird is endemic to the high peaks, the mountain pipit (Anthus hoeschi), and another six species are found mainly here: Bush blackcap (Lioptilus nigricapillus), buff streaked chat (Oenanthe bifasciata), Rudd's lark (Heteromirafra ruddi), Drakensberg rockjumper (Chaetops aurantius), yellow breasted pipit (Anthus chloris), and Drakensberg siskin (Serinus symonsi). The endangered Cape vulture and lesser kestrel are two of the birds of prey that hunt in the mountains. Mammals include klipspringer (Oreotragus oreotragus), eland (Taurotragus oryx), and mountain reedbuck (Redunca fulvorufula). Other endemic species include three frogs found in the mountain streams, Drakensberg river frog (Amietia dracomontana), Phofung river frog (Amietia vertebralis), and Maluti river frog (Amietia umbraculata). Fish are found in the many rivers and streams, including the Maluti redfin (Pseudobarbus quathlambae) that was thought to be extinct before being found in the Senqunyane River in Lesotho. The lower slopes of the Drakensberg support much wildlife, perhaps most importantly the rare southern white rhinoceros (which was nurtured here when facing extinction) and the black wildebeest (Connochaetes gnou, which only thrives in protected areas and game reserves). The area is home to large herds of grazing fauna and antelopes such as eland (Taurotragus oryx), reedbuck (Redunca arundinum), mountain reedbuck (Redunca fulvorufula), grey rhebok (Pelea capreolus), and even some oribi (Ourebia ourebi). Chacma baboons also are present. Endemic species include a large number of chameleons and other reptiles. There is one endemic frog, the forest rain frog (Breviceps sylvestris), and four more species that are found mainly in these mountains; long toed tree frog (Leptopelis xenodactylus), plaintive rain frog (Breviceps maculatus), rough rain frog (Breviceps verrucosus), and Poynton's caco (Cacosternum poyntoni).

The high slopes are hard to reach so the environment is fairly undamaged. However, tourism in the Drakensberg is developing, with a variety of hiking trails, hotels, and resorts appearing on the slopes. Much of the higher South African parts of the range have been designated as game reserves or wilderness areas. 7% of the Drakensberg alti montane grasslands and woodlands ecoregion is in protected areas. These include Golden Gate Highlands National Park, Sehlabathebe National Park, Tsehlanyane National Park, Malekgalonyane Nature Reserve, Giant's Castle Game Reserve, Loteni Nature Reserve, Natal National Park, Vergelegen Nature Reserve, Beaumont Nature Reserve, and Lammergeier Highlands Nature Reserve. Of these the uKhahlamba Drakensberg Park was listed by UNESCO in 2000 as a World Heritage site. The park also is in the List of Wetlands of International Importance (under the Ramsar Convention). The Royal Natal National Park, which contains some of the higher peaks, is part of this large park complex. Adjacent to the Ukhahlamba Drakensberg World Heritage Site is the 1900 ha Allendale Mountain Reserve, which is the largest private reserve adjoining the World Heritage Site and is found in the accessible Kamberg area, the heart of the historic San (Bushman) painting region of the Ukhahlamba. The grassland of the lower slopes has been greatly affected by agriculture, however, especially by overgrazing. Nearly all of the original grassland and forest has disappeared and more protection is needed, although the Giant's Castle reserve is a haven for the eland and also is a breeding ground for the bearded vulture. 5.81% of the Drakensberg montane grasslands, woodlands and forests ecoregion is in protected areas. These include Kruger National Park, Mountain Zebra National Park, Golden Gate Highlands National Park, Camdeboo National Park, Sehlabathebe National Park, and Tsehlanyane National Park. The Maloti Drakensberg Transfrontier Conservation Area was established to preserve some of the high mountain areas of the range.

Towns and cities in the Drakensberg area include, from south to north, Matatiele and Barkly East in the Kwa Zulu Natal Province; Ladysmith, Newcastle, Ulundi – the former Zulu capital, Dundee, and Ixopo in KwaZulu Natal; all of Lesotho, whose capital is Maseru; and Tzaneen in Limpopo Province.
