Hahn, South Africa undoubtedly has a rich geomorphological heri-, tage which has been recognized and celebrated through a, variety of mechanisms such as the display of iconic landscapes. Numerous (major) rivers comprise the overall system, including the Albert Nile, Blue Nile, Victoria Nile and White Nile.

Neon isotopes indicate that the melts originate from a deep mantle source that is similar to the mantle plume beneath Réunion, rather than the convecting upper mantle or sub-continental lithosphere. Indeed, many landscapes or geologic/geomorphic phenomena, across South Africa are attributes that form part of provincial, or national heritage sites, being inscribed as World Heritage, The wider context for landscape management and conserva-, tion in South Africa is the backdrop of ongoing climate.

Conversely, the interdunes generally exhibit relatively rich seed banks. Topography includes areas of rock-strew plains, rolling sand dunes and numerous sand seas.

Climatic shifts, and biome and geographic changes possibly functioned as major driving forces in shaping cladogenesis, population dynamics and genetic structure in southern African tortoise species. Southern Africa was drained by two river This chapter introduces the broader context for the diverse South African landscapes and landforms discussed in this book. Gold! today, emerged as South America; the Falkland Plateau and, Antarctica separated from southern Africa in the period, The geologic history of South Africa and the development of, its topography and landscapes are very closely linked, par-, ticularly over the Cenozoic (last 66 Ma). The desert's sand dunes, some of which are 300 m (980 ft.) high and span 32 km (20 mi) long, are the second largest in the world after the Badain Jaran Desert dunes in China. 12); 20c (Drakensberg-see Chap.

Among the topics covered are the inter-relationships between the Mesozoic basins of the South African southern offshore as far as the Agulhas Bank, Gondwana tectonics and the Cape Fold Belt (CFB).

Using field observations and soil seed bank experiments, we show that palatable perennial grass cover is reduced while the seedbank is depleted on grazed dunefields.
