The Manengouba is an extinct stratovolcano on the border of the provinces of Sud -Ouest and Littoral, Cameroon. It reaches an altitude of 2,411 meters above sea level and is part of the Cameroon line. The nearest towns are Nkongsamba and Melong. North of the Manengouba is the Bambouto massif and southwest of Mount Kupe.
The Manengouba one of the younger volcanoes of the Cameroon line, its development started about 1.55 million years and is divided into three phases of development. In the first phase, the Elengoum developed, named after its caldera, before approximately 1.55 million to 700,000 years. After this volcano collapsed and its caldera formed the Eboga, also called Ebwo developed, about 560,000 years ago. Its caldera was formed about 480,000 years ago and represents the third phase
The summit region of the volcano is dominated by two calderas, the Eboga ( Ebwo ) - and the Elengoum caldera. The Ebwo caldera lies at an altitude of 1,950 meters, has a diameter of 3 kilometers. At its center are the Male and Female Lake, which together have a capacity of about 40 million cubic meters of water and are visited by the local people for medicinal purposes. Both lakes were named because of their color, the times Lake has a bluish, and is fortified with calcium, magnesium and sodium. The Female Lake has a greenish coloration and is rich in bicarbonates. The deeper Elengoum caldera has a diameter of six kilometers, but it is less pronounced due to the erosion of the crater walls. Between the two calderas is the highest elevation of Manengouba, a mountain rain forest spreads to the southern mountain slopes located. The summit region of Manengouba is called by the resident tribe of Bakossi Mwaam. Total living on Manengouba approximately 70,000 people.
The massif of Manengouba has a great ecological importance because 50 % of the endemic living in the Cameroon Mountains anurans occur here, including the long finger frog Leptodactylodon erythrogaster and Cardioglossa trifasciata. From the avifauna of 270 species of birds on Manengouba are located. At its wooded slopes of the holotype of the collar Strangler ( Telophorus kupeensis ) and the mouse sailor was ( Schoutedenapus myoptilus ) found and described for the first time. In mammals come on Manengouba among others, the white tooth shrew Crocidura manengubae, the African forest shrew Myosorex okuensis and the African climbing mouse Dendromus oreas ago.
