Robertson Karoo
Robertson Karoo is a semi-arid vegetation type, restricted to sections of the Breede River Valley, Western Cape Province, South Africa. It is a subtype of Succulent Karoo (geographically an extension of the "Little Karoo") and is characterised by the dominance of succulent plant species, and by several endemic plants and animals. Location and extent This vegetation type occurs in several large patches within the Breede River Valley, in the Western Cape Province of South Africa. It occurs in the area between Worcester in the north-west, Ashton in the east, and the Riviersonderend mountains in the south. Landscape and climate Robertson Karoo typically consists of low hills and flats covered in small succulent vegetation, usually growing on rocky shale-based soils. The climate is semi-arid due to the region lying in the rainshadow of the large mountain ranges to the south-west, but the rainfall does tend to occur mainly in winter. This vegetation type has a large number of ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Cape Province
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total. It is roughly the size of England or the St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Renosterveld
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region (Cape Floral Kingdom) which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome. Etymology Renosterveld directly translated in the Afrikaans language means "rhinoceros-field", a possible reference to the high number of rhinoceroses seen by the Afrikaner settlers at the time. It may also derive its name from the renosterbos ("rhinoceros bush - ''Elytropappus rhinocerotis''), which is a common species of shrub found here. The dull grey colour of renosterbos is similar to the colour of a rhino's hide. Geology Renosterveld plants grow on rich soil, which makes them more nutritious than typical fynbos plants. Typically, renosterveld is largely confined to fine-grained soils - mainly clays and silts - which are derived from the shales of the Malmesbury and Bokkeve ...

Fynbos
Fynbos (; meaning fine plants) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Overview and history The word fynbos is often confusingly said to mean "fine bush" in Afrikaans, as "bos" means "bush". Typical fynbos foliage is ericoid rather than fine. The term, in its pre-Afrikaans, Dutch form, ''fynbosch'', was recorded by Nob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eriospermum Bayeri
''Eriospermum bayeri'' is a species of geophytic plant of the genus ''Eriospermum'', indigenous to the Western Cape Province, South Africa.
