Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Mount Fako (the name of the higher of its two peaks) or by its indigenous name Mongo ma Ndemi (“Mountain of Greatness”).
It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa and the 31st-most prominent in the world. The mountain is part of the area of volcanic activity known as the Cameroon Volcanic Line which also includes Lake Nyos, the site of a disaster in 1986. The most recent eruption occurred on February 3, 2012.
Mount Cameroon is one of Africa’s largest volcanoes, rising to 4,040 metres (13,255 ft) above the coast of west Cameroon. It rises from the coast through tropical rainforest to a bare summit, which is cold, windy and occasionally dusted with snow. The massive steep-sided volcano of dominantly basaltic-to-trachybasaltic composition forms a volcanic horst constructed above a basement of Precambrian metamorphic rocks covered with Cretaceous to Quaternary sediments. More than 100 small cinder cones often fissure-controlled parallel to the long axis of the massive 1,400-cubic-kilometre (336 cu mi) volcano occur on the flanks and surrounding lowlands. A large satellitic peak, Etinde (also known as Little Mount Cameroon) is located on the southern flank near the coast.
Mount Cameroon has the most frequent eruptions of any West African volcano. The first written account of volcanic activity could be the one from the Carthaginian Hanno the Navigator who may have observed the mountain in the 5th century BC. Moderate explosive and effusive eruptions have occurred throughout history from both summit and flank vents. A 1922 eruption on the southwestern flank produced a lava flow that reached the Atlantic coast. A lava flow from a 1999 south-flank eruption stopped 200 metres (656 ft) from the sea cutting the coastal highway.
The mountain’s natural vegetation varies with elevation. The main plant communities on the mountain include:
Lowland rain forest predominates on the lower slopes from sea level to 800 metres (2,625 ft) elevation. The lowland forests are part of the Cross-Sanaga-Bioko coastal forests ecoregion.
There are composed of evergreen trees with a dense canopy 25 to 30 metres (82 to 98 ft) high with taller emergent trees rising above the canopy. The forests are diverse and species-rich with numerous lianas. Much of the lowland forest has been converted to agriculture and agroforestry including oil palm plantations.
Lower montane forest, also known as submontane forest or cloud forest, grows between 800 and 1,600 metres (2,625 and 5,249 ft) elevation. The lower montane forests are composed of evergreen trees, which form a 20–25-metre-high (66–82 ft) canopy that is either closed or discontinuous. There are scattered areas of meadow and scrubland, with grasses, herbs, tall herbaceous plants (including Acanthaceae), tree ferns, woody shrubs, and low trees. Frequent clouds and mists sustain profuse epiphytes, including mosses, ferns, and orchids. The lower montane forests are diverse and species-rich, with characteristic Afromontane plants and endemic species. Impatiens etindensis and grandisepala are herbaceous epiphytes endemic to the montane forests of Mount Cameroon.
The lower montane forests together with the higher-elevation forests, scrub, and grasslands, are part of the Mount Cameroon and Bioko montane forests ecoregion.
Upper montane forest grows from 1,600–1,800 metres (5,249–5,906 ft) elevation. Trees up to 20 metres (66 ft) high form an open-canopied forest with numerous epiphytes. The upper montane forests are less species-rich than the lower-elevation forests and fires are more frequent.
Montane scrub grows between 1,800 and 2,400 metres (5,906 and 7,874 ft) elevation. Low trees of 1 to 15 metres (3 to 49 ft) form open-canopied forests, woodlands, and shrublands, with an understory of small shrubs, herbs, ferns, and climbers.
Montane grassland occurs between 2,000 and 3,000 metres (6,562 and 9,843 ft) elevation. The dominant vegetation is tussock grasses, with scattered fire-tolerant shrubs and low trees.
Sub-alpine grassland is found at the highest elevations, from 3,000 metres (9,843 ft) to over 4,000 metres (13,123 ft). Frost-tolerant tussock grasses, dwarf trees and shrubs, and crustose, foliose and fruticose lichens predominate.
Fauna and flora
Large mammals on the mountain include the African forest elephant (Loxodonta cyclotis), with a population of over 100 individuals. Other herbivores include red river hog (Potamochoerus porcus), bushbuck (Tragelaphus scriptus), bay duiker (Cephalophus dorsalis), blue duiker (Philantomba monticola), and yellow-backed duiker (Cephalophus sylvicultor).
The mountain is home to several species of primates, including chimpanzee (Pan troglodytes), drill (Mandrillus leucophaeus), red-capped mangabey (Cercocebos torquatus), putty-nosed monkey (Cercopithecus nictitans), mona monkey (Cercopithecus mona), red-eared monkey (Cercopithecus erythrotis), Preuss’ guenon (Cercopithecus preussii), and crowned guenon (Cercopithecus pogonias).
Two species of birds are endemic to Mount Cameroon, Mount Cameroon spurfowl (Pternistis camerunensis) and Mount Cameroon speirops (Zosterops melanocephalus).
