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 possibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds the Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar. Senegal is notably the westernmost country in the mainland of the Old World, or Afro-Eurasia. It owes its name to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worldwide Fund For Nature
The World Wide Fund for Nature Inc. (WWF) is an international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. WWF is the world's largest conservation organization, with over five million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects. They have invested over $1 billion in more than 12,000 conservation initiatives since 1995.

Tropical And Subtropical Grasslands, Savannas, And Shrublands
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Description Grassland is dominated by grass and other herbaceous plants. Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, whil ...

Sahelian Acacia Savanna
The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry ha ...

West Sudanian Savanna
The West Sudanian savanna is a tropical savanna ecoregion that extends across West Africa. Geography The ecoregion stretches east and west across West Africa, from the Atlantic coast of Senegal to the Mandara Mountains on Nigeria's eastern border. The drier Sahelian Acacia savanna lies to the north, and the more humid Guinean forest-savanna mosaic lies to the south. Climate The climate is a tropical savanna climate and a hot semi-arid climate (Köppen climate classification ''Aw'' and ''BSh'') with a dry season and a wet season and the temperature being warm and hot year-round. Annual rainfall ranges from 1000 mm in the south to 600 mm in the north on the edge of the Sahel. Rainfall and temperature vary seasonally, with a hot rainy season from May to September, and a cooler dry season from October to April. Temperatures range from 30 °C to 33 °C during the hottest month, and 18 °C to 21 °C during the coolest month. Examples Flora Sa ...

Mangrove
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 w ...

Guinean Mangroves
The Guinean mangroves are a coastal ecoregion of mangrove swamps in rivers and estuaries near the ocean of West Africa from Senegal to Sierra Leone. Location and description Guinean mangroves can be found: in the Saloum River and Casamance deltas in Senegal; in the lower Gambia River basin; much of the coast of Guinea-Bissau, including the Cacheu and Mansoa Rivers; across the border in northern Guinea; and much of the coast of Sierra Leone including the Sherbro River. Mangroves thrive on flat coastal inlets and estuaries where the ocean tides wash warm salt water high upriver, in this ecoregion as far as 100 km, for example in the Cacheu River of Guinea-Bissau. Flora The mangroves have a varied composition with '' Rhizophora'', '' Laguncularia racemosa'' and ''Conocarpus erectus'' growing up to 10m tall among larger areas of ''Rhizophora'' and '' Avicennia''. The tallest trees may be and form the equivalent of gallery forests along the creeks, the mudflats bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gambia River
The Gambia River (formerly known as the River Gambra) is a major river in West Africa, running from the Fouta Djallon plateau in north Guinea westward through Senegal and The Gambia to the Atlantic Ocean at the city of Banjul. It is navigable for about half that length. The river is strongly associated with The Gambia, the smallest country in mainland Africa, which occupies the downstream half of the river and its two banks. Geography The Gambia River runs a total length of . From the Fouta Djallon, it runs northwest into the Tambacounda Region of Senegal, where it flows through the Parc National du Niokolo Koba, then is joined by the Nieri Ko and and passing through the Barrakunda Falls before entering the Gambia at Koina. At this point, the river runs generally west, but in a meandering course with a number of oxbows, and about from its mouth it gradually widens, to over wide where it meets the sea. Crossings There are several bridges crossing the river. The largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
