Lake Oku
Lake Oku is a crater lake on the Bamenda Plateau in the Northwest Region of Cameroon. It is located at on Mount Oku, and is completely surrounded by cloud forest. The lake lies in an explosion crater formed in the last phase of development of the Oku Massif, a large volcanic field with a diameter of about . Mount Oku is a stratovolcano that rises to . The lake is the subject of many myths among the local people. The lake is the only known habitat of the Lake Oku Clawed Frog. The surrounding Kilum-Ijim Forest is a nature reserve, set up by BirdLife International, and home to many rare species.

Kilum-Ijim Forest
The Kilum-Ijim Forest is an area of mountain rainforest in Cameroon's North-West Region. It is found on Mount Oku and the nearby Ijim Ridge in the Cameroon mountains, with Lake Oku lying in a crater in its center. It is the largest area of Afromontane forest left in West Africa. The area is an important one for biodiversity, including the endemic Bannerman's turaco Bannerman's turaco (''Tauraco bannermani'') is a species of bird in the family Musophagidae. It is endemic to Cameroon. In French it is known as ''touraco de Bannerman'' or ''touraco doré''. Its scientific and common names honour the ornitholo ... and banded wattle-eye. The forest is the focus of a successful community conservation project, the Kilum-Ijim Forest Project, which works to protect the forest. The project is a collaboration between the Cameroon Ministry of the Environment and BirdLife International, and focuses on sustainable use of the forests, local management, working to benefit both the biodive ...

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Lake Ejagham
Lake Ejagham is a small lake near Eyumodjock in the Southwest Region, Cameroon, Southwest Region of Cameroon. Unlike many other lakes in the region, it is not a volcanic lake, but is likely a solution basin formed by groundwater during the last glacial period, last Ice Age. This highly isolated lake is roughly oval in shape, lacks an inflow, but has an outflow into the Munaya River (part of the Cross River (Nigeria), Cross River system).Schliewen, U.K., Tautz, D., and Pääbo, S.

Lake Barombi Mbo
Lake Barombi Mbo or Barombi-ma-Mbu is a lake near Kumba in the Southwest Region of Cameroon. It is located in the Cameroon volcanic chain, and is the largest volcanic lake in this region. It is one of the oldest radiocarbon-dated lakes in Africa, with the youngest lava flow in it being about one million years old. On old colonial maps the area was known as Elefanten Sea (Elephant Lake), but the elephants living in the area were extirpated due to ivory trading. Biology Until now, 15 species of fishes have been recorded from the lake.Freshwater Ecoregions of the World (2008). Western Equatorial Crater Lakes.'' Among others, this includes ''Labeobarbus batesii'', a member of the '' Fundulopanchax mirabilis'' group, and the endemic catfish '' Clarias maclareni''. Perhaps most noteworthy are the 11 species of cichlids that are endemic to the lake ('' Konia spp.'', ''Stomatepia spp.'', ''Myaka myaka'', ''Pungu maclareni'', ''Sarotherodon caroli'', '' S. linnellii'', '' S. lohberge ...

Lake Barombi Koto
Lake Barombi Koto, also known as Lake Barombi Kotto or Lake Barombi-ba-Kotto, is a small lake in the volcanic chain in the Southwest Region of Cameroon. It is a volcanic lake with a diameter of about . There is a small island in the middle, which is densely inhabited by the Barombi, a tribe of fishers. The Tung Nsuia and Tung Nsuria streams, each about wide and deep near their mouth, are the only inflows into the lake, and they dry out in dry season. Biology Lake Barombi Koto often appears green-brown because it is rich in phytoplankton. Invertebrates, turtles and the aquatic frog ''Xenopus tropicalis'' are common in the lake, which is also an important sanctuary for birds. Seven fish species are known from the lake, including '' Enteromius callipterus'' and a ''Clarias'' catfish, while the remaining all are cichlids: '' Coptodon kottae'', '' Chromidotilapia guentheri'', ''Hemichromis fasciatus'', '' Pelmatolapia mariae'' and ''Sarotherodon galilaeus''.

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
