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 Niger Delta mangroves, 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 (Nigeria), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douala Edéa National Park

Rhizophora Mangle
''Rhizophora mangle'', also known as the red mangrove, is a salt-tolerant, small-to-medium sized evergreen tree restricted to coastal, estuarine ecosystems along the southern portions of North America, the Caribbean as well as Central America and tropical West Africa. Its viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows. ''Rhizophora mangle'' grows on aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. The name refers to the red colour on the inner part of its roots when halved, so it does not display any red colour in its regular appearance. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree ''(Schinus terebinthifolius)''. The red mangrove itself is co ...

Benguela Current
The Benguela Current is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre. The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela Front in the north, at around 16°S. The current is driven by the prevailing south easterly trade winds. Inshore of the Benguela Current proper, the south easterly winds drive coastal upwelling, forming the Benguela Upwelling System. The cold, nutrient rich waters that upwell from around depth in turn fuel high rates of phytoplankton growth, and sustain the productive Benguela ecosystem. Boundaries Source waters for the Benguela include cold upwelled waters from the depths of the Atlantic Ocean close inshore, joined further off-shore by nutrient poor water that has crossed the Southern Atlantic from South America as part of South Atlantic Gyre. Eddies from the warm South Indian Ocean Agulhas current along South Africa's east coast come round the Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wouri Estuary
The Wouri estuary, or Cameroon estuary is a large tidal estuary in Cameroon where several rivers come together, emptying into the Bight of Biafra. Douala, the largest city in Cameroon, is at the mouth of the Wouri River where it enters the estuary.

Hydrology The estuary lies to the east of Mount Cameroon and empties into the Bight of Biafra. It is fed by the Mungo River, Cameroon, Mungo, Wouri River, Wouri and Dibamba River, Dibamba rivers. The estuary lies in the Douala Basin, a low-lying depression about on average about sea level, with many creeks, sand bars and lagoons. The Plio-Pleistocene Wouri alluvial aquifer, a multi-layer system with alternating sequences of marine sands and estuarine mud and silt lies below the estuary and surrounding region and is an important source of well water.

Cross River (Nigeria)
Cross River (native name: Oyono) is the main river in southeastern Nigeria and gives its name to Cross River State. It originates in Cameroon, where it takes the name of the Manyu River. Although not long by African standards its catchment has high rainfall and it becomes very wide. Over its last to the sea it flows through swampy rainforest with numerous creeks and forms an inland delta near its confluence with the Calabar River, about wide and long between the cities of Oron on the west bank and Calabar, on the east bank, more than from the open sea. The delta empties into a broad estuary which it shares with a few smaller rivers. At its mouth in the Atlantic Ocean, the estuary is wide. The eastern side of the estuary is in the neighboring country of Cameroon. The major tributary of Cross River is the river Aloma, coming from Benue State to merge with Cross River in Cross River State. Cross River State is connected with a major highway to its sister state Akwa Ibom. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Guinea
The Gulf of Guinea (French language, French: ''Golfe de Guinée''; Spanish language, Spanish: ''Golfo de Guinea''; Portuguese language, Portuguese: ''Golfo da Guiné'') is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. Null Island, defined as the intersection of the Equator and Prime Meridian (zero degrees latitude and longitude), is in the gulf. Among the many rivers that drain into the Gulf of Guinea are the Niger River, Niger and the Volta River, Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny. Name "Guinea" is thought to have originated from a local name for an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name "Guinea (region), Guinea" was also previously applied to the south coast of West Africa (north of the Gulf of Guinea), which became known as "Upper Guinea", and to the west coast of Southern Afri ...

Niger Delta Mangroves
Nigeria has extensive mangrove forests in the coastal region of the Niger Delta. Considered one of the most ecologically sensitive regions in the world, the Niger Delta mangrove forest is situated within a deltaic depositional environment. These mangrove forests serve a critical role in regional ecological and landscape composition, and support subsistence gathering practices, and market-based income opportunities. Human impact on the environment, Anthropogenic development threatens the survival of Niger Delta mangrove populations. Overview Mangrove forests are found in 118 countries and territories worldwide, 75% of mangrove vegetation zones are located in intertidal Tropics, tropic and sub-tropic habitats situated between 25° N and 25° S . Typically surrounding salient river deltas, mangrove regions support a variety of halophytes. These robust shrubs and trees, which have adapted to changing coastal conditions (such as inundation, sun exposure, anaerobic soil, and salini ...
