Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Grasslands And Shrublands
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline. This biome includes high elevation (montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the And ...

Namib Coastal
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and cont ...

Etosha
Etosha National Park is a national park in northwestern Namibia and one of the largest national parks in Africa. It was proclaimed a game reserve in March 1907 in Ordinance 88 by the Governor of German South West Africa, Friedrich von Lindequist. It was designated as ''Wildschutzgebiet'' in 1958, and was elevated to the status of a national park in 1967 by an act of parliament of the Republic of South Africa. It spans an area of and gets its name from the large Etosha pan which is almost entirely within the park. With an area of , the Etosha pan covers 23% of the total area of the national park. The area is home to hundreds of species of mammals, birds and reptiles, including several threatened and endangered species such as the black rhinoceros. The park is located in the Kunene region and shares boundaries with the regions of Oshana, Oshikoto and Otjozondjupa. History Areas north of the Etosha pan were inhabited by Ovambo people, while various Otjiherero-speaking groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuanza River
The Kwanza River, also known as the Coanza, the Quanza, and the Cuanza, is one of the longest rivers in Angola. It empties into the Atlantic Ocean just south of the national capital Luanda. Geography The river is navigable for about from its mouth, located south of Luanda. Its tributaries included the Cutato and Lucala. History The river's navigable lower course was the original route of Portugal invasion into northern Angola. The Capanda Dam in Malanje Province was finished in 2004, providing hydroelectric power to the region and assisting its irrigation. The Cambambe Dam and the Lauca Dam were also constructed on the river. The Caculo Cabaça Hydroelectric Power StationCaculo Cabaça Dam is under construction with estimated completion in 2024. The ''Barra do Kwanza'', the mouth of the river is gradually being developed for tourism, including a golf course. The Church of Nossa Senhora da Victoria stands near the banks of the Kwanza River in Massanganu, Province of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congo (area)
The Congo Basin (french: Bassin du Congo) is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity, many experts have characterized the basin's forest as important for mitigating climate change because of its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kasai River
The Kasai River ( ; called Cassai in Angola) is a tributary (left side) of the Congo River, located in Central Africa. The river begins in central Angola and flows to the east until it reaches the border between Angola and the Democratic Republic of the Congo, where it turns north and serves as the border until it flows into the DRC. From Ilebo, between the confluences with Lulua river and Sankuru river, the Kasai river turns to a westerly direction. The lower stretch of the river from the confluence with Fimi river, is known as the Kwa(h) River, before it joins the Congo at Kwamouth northeast of Kinshasa. The Kasai basin consists mainly of equatorial rainforest areas, which provide an agricultural land in a region noted for its infertile, sandy soil. It is a tributary of Congo river and diamonds are found in it. Around 60% of diamonds in Belgium go from Kasai river for cutting and shaping. Exploration Henry Morton Stanley reached the confluence on 9 March 1877, calling the rive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central African Mangroves
The Central African mangroves ecoregion consists of the largest area of mangrove swamp in Africa, located on the coasts of West Africa, mainly in Nigeria. Location and description These mangroves are found in fertile rivermouths and lagoons and contain trees up to 45m tall. Most are in Nigeria, with important areas Cameroon and Equatorial Guinea/Gabon and patches in Ghana, Democratic Republic of Congo, and northern Angola. The largest area in the region is on the delta of the Niger River on the Gulf of Guinea, while others include the eastern side of the Cross River delta in Nigeria and Cameroon, the Wouri estuary in Cameroon, and the Muni River estuary on the border of Equatorial Guinea and Gabon, and the mouth of the Congo River. As well as being home to much wildlife the mangroves hold rivers in place, filter the waters and create build-ups of nutrient-rich soil on the banks. Mangroves thrive in humid tropical climates where the sea is warm, and where high tides flood into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangroves
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of water ...

Namibian Savanna Woodlands
The Namibian savanna woodlands, also known as the Namib escarpment woodlands, are deserts and xeric shrublands ecoregion of Namibia and Angola. Geography They extend north and south from southwestern Angola to central Namibia, east of the coastal Namib Desert. The woodlands cover the Namib escarpment, which rises from the low-lying Namib coastal plain to the Southern African plateau on the east. Baynes (2038 m), Erongo (2319 m), Naukluft (1974 m), Spitzkoppe (1759 m), and Gamsberg (2347 m) mountains lie along the edge of the escarpment. Brandberg Mountain (257 m) lies west of the escarpment in the Namib Desert, and is included in the ecoregion.Burgess, Neil, Jennifer D'Amico Hales, Emma Underwood, et al. (2004).

Kaokoveld Desert
The Kaokoveld Desert is a coastal desert of northern Namibia and southern Angola. Setting The Kaokoveld Desert occupies a coastal strip covering , from 13° to 21°S and is bounded by the Atlantic Ocean to the west, the Namibian savanna woodlands to the east, and the Namib Desert to the south. It includes the Moçâmedes Desert of southern Angola. The Kaokoveld is a harsh desert of drifting sandunes and rocky mountains. It receives most of its rainfall during the summer, which distinguishes it from the adjacent Namib Desert to the south, which receives most of its rain during the winter. The Kunene River is the only permanent watercourse but many dry riverbeds (including the Hoanib, Hoarusib and Khumib Rivers) carry moisture through the desert and are home to animals including elephants, black rhinos, and giraffe. Other than those the area is ancient desert sand, moistened by occasional coastal fog. Flora The Kaokoveld is home to ''Welwitschia mirabilis'', a plant that has no ...
