Kouga River
The Kouga River originates near Uniondale, Eastern Cape, South Africa, and flows eastward, where it joins the Groot River to form the Gamtoos just past the Kouga Dam. Its main tributary is the Baviaanskloof River, which joins its left bank before the dam. The Kouga is part of the Gamtoos river system which is formed by the Groot and the Baviaanskloof River. The Kouga Mountains to the north the river, Kouga Municipality and Kou-Kamma Municipality are named after this waterbody. Ecology In 1995 specimens of the Cape galaxias (''Galaxias zebratus''), a South African fish species endemic to the Cape Floristic Region, were found in the Kouga and in the Krom River. Until then it had been thought that its distribution was restricted to the area between the Keurbooms and the Olifants River. Although in South Africa this relatively delicate fish is only classified as near threatened, in Australia species of the same genus were driven to extinction by competing salmonids and other i ...

Khoekhoe Language
The Khoekhoe language (), also known by the ethnic terms Nama (''Namagowab'') , Damara (''ǂNūkhoegowab''), or Nama/Damara and formerly as Hottentot, is the most widespread of the non-Bantu languages of Southern Africa that make heavy use of click consonants and therefore were formerly classified as Khoisan, a grouping now recognized as obsolete. It belongs to the Khoe language family, and is spoken in Namibia, Botswana, and South Africa primarily by three ethnic groups: Namakhoen, ǂNūkhoen, and Haiǁomkhoen. History The Haiǁom, who had spoken a Juu language, later shifted to Khoekhoe. The name for the speakers, ''Khoekhoen'', is from the word ''khoe'' "person", with reduplication and the suffix ''-n'' to indicate the general plural. Georg Friedrich Wreede was the first European to study the language, after arriving in ǁHui!gaeb (later Cape Town) in 1659. Status Khoekhoe is a national language in Namibia. In Namibia and South Africa, state-owned broadcasting co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krom River
Krom River or Kromme River ( af, Krommerivier) is a river in the Eastern Cape Province in South Africa. The river flows into the Indian Ocean through an estuary on the north side of St Francis Bay, west of Port Elizabeth. The Krom river flows in an ESE direction and is approximately 109 km long with a catchment area of 1,085 km. The Churchill Dam and the Impofu Dam are dams on the Krom River. The latter is located near Humansdorp. Presently this river is part of the Fish to Tsitsikama Water Management Area.

List Of Drainage Basins Of South Africa
A drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The drainage basin acts like a funnel, collecting all the water within the area covered by the basin and channelling it into a waterway. Each drainage basin is separated topographically from adjacent basins by a geographical barrier such as a ridge, hill or mountain, which is known as a water divide. Other terms that are used to describe a drainage basin are catchment, catchment area, catchment basin, drainage area, river basin, water basin and watershed. The drainage basins in South Africa do not correspond with the Water Management Areas, and have the letters A, B, C, D, E, F, G, H, J ...

List Of Rivers Of South Africa
This is a list of rivers in South Africa. It is quite common to find the Afrikaans word ''-rivier'' as part of the name. Another common suffix is "''-kamma''", from the Khoisan term for "river" Meiring, Barbara"South African Toponymic Guidelines for Map and other editors: Fourth Edition" 12. Retrieved on 30 April 2013. (often tautologically the English term "river" is added to the name). The Zulu word ''amanzi'' (water) also forms part of some river names. The Afrikaans term ''spruit'' (compare spring) often labels small rivers.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonid
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies, with rounded scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Olifants River (Western Cape)
The Olifants River ( af, Olifantsrivier) is a river in the northwestern area of the Western Cape Province of South Africa. The upper and main catchment area of the Olifants river is around Ceres and the Cederberg mountains. The Clanwilliam and Bulshoek dams are located on the river and provide water for the towns and farms along the watercourse. The river is approximately 285 km long with a catchment area of 46,220 km2 and flows into the Atlantic Ocean at Papendorp, 250 km north of Cape Town. Watershed The Olifants River rises in the Winterhoek Mountains north of Ceres. The mainstem is about 265 km long. The river flows to the north-west through a deep, narrow valley that widens and flattens into a broad floodplain below Clanwilliam. The river eventually drains into the Atlantic Ocean near Papendorp. At the mouth the Olifants river is split in two by an island that exhibits interesting rock formations. Tributaries Its main tributary is the Doring River, ch ...
