Zambezian Baikiaea Woodlands
The Zambezian ''Baikiaea'' woodlands is an ecoregion in Africa. It includes dry deciduous forest and woodland, thicket, and grassland, dominated by the tree ''Baikiaea plurijuga''. The ecoregion has a semi-arid climate, and is a transition between more humid miombo woodlands to the north, and the drier Kalahari Acacia-Baikiaea woodlands The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for , covering much of Botswana, and parts of Namibia and South Africa.

Baikiaea Plurijuga
''Baikiaea plurijuga'', known as African teak, Mukusi, Rhodesian teak, Zambian teak or Zambesi redwood, is a species of Afrotropical tree from the legume family, the Fabaceae from southern Africa. Description ''Baikiaea plurijuga'' is a medium-sized deciduous tree with pinnate leaves each with 4-5 pairs of opposed leaflets. They show pink to deep mauve flowers have yellow stamens and are clustered in large axillary racemes; it flowers from November to April. The fruit are flattened, woody pods with a hooked tip which splits explosively sending the seeds out over some distance. Habitat ''Baikiaea plurijuga'' is confined to the Kalahari sands and the woodland which it dominates is known as Gusu woodland. This woodland grows on the deep, aeolian and fluvial Kalahari Sands which have virtually no clay or silt. These sands provide exceptional growing conditions for deep-rooting trees, but the deficiency in clay restricts tree growth to sites holding nutrients in the form of organ ...

Ecoregions Of Zambia
The biomes and ecoregions in the ecology of Zambia are described, listed and mapped here, following the World Wildlife Fund's classification scheme for terrestrial ecoregions, and the WWF freshwater ecoregion classification for rivers, lakes and wetlands. Zambia is in the Zambezian region of the Afrotropical biogeographic realm (or ecozone). Three terrestrial biomes are well represented in the country (with an additional one extending a few kilometres over the border). The distribution of the biomes and ecoregions is governed mainly by the physical environment, especially climate. Physical environment The main aspects of the physical environment which determine the biomes and ecoregions of Zambia are: climate, specifically rainfall amount, length of the dry season, and temperature, which is related to elevation; and soils and bushfires. Climate Rainfall Rainfall amount is the most important determinant of the type and distribution of ecoregions. Zambia experiences good rainfa ...

Afrotropical Ecoregions
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalahari Acacia-Baikiaea Woodlands
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for , covering much of Botswana, and parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoegowab origin and means "vast place". Etymology ''Kalahari'' is derived from the Tswana word ''Kgala'', meaning "the great thirst", or ''Kgalagadi'', meaning "a waterless place"; the Kalahari has vast areas covered by red sand without any permanent surface water. History The Kalahari Desert was not always a dry desert. The fossil flora and fauna from Gcwihaba Cave in Botswana indicates that the region was much wetter and cooler at least from 30 to 11 thousand BP (before present) especially after 17,500 BP. Geography Drainage of the desert is by dry black valleys, seasonally inundated pans and the large salt pans of the Makgadikgadi Pan in Botswana and Etosha Pan in Namibia. The only permanent river, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miombo Woodlands
The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located primarily in Central Africa. It includes four woodland savanna ecoregions (listed below) characterized by the dominant presence of ''Brachystegia'' and ''Julbernardia'' species of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss and produce a flush of new leaves just before the onset of the wet season with rich gold and red colours masking the underlying chlorophyll, reminiscent of autumn colours in the temperate zone. The woodland gets its name from ''miombo'' (plural, singular ''muombo''), the Bemba word for ''Brachystegia'' species. Other Bantu languages of the region, such as Swahili and Shona, have related if not identical words, such as Swahili ''miyombo'' (singu ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
