Isoglossa nervosa is a species of plant in the family Acanthaceae. It is an herbaceous perennial or subshrub native to southeastern Nigeria, Cameroon, and Bioko island in Equatorial Guinea. [2] Its natural habitat is tropical montane forest from 2,000 to 2,950 meters elevation. [1]
It has been recorded at Pico Basilé on Bioko, on Mount Cameroon and Mann's Spring, Bokwangwo, Bamboutos, Mount Oku, and the Adamawa Plateau in Cameroon, and Mabile-Ngelyaki in Nigeria. [1] It grows in upper montane forest with Podocarpus milanjianus , Prunus africana , Myrsine melanophloeos , Nuxia congesta , and Syzygium guineense , as well as bamboo thicket, forest-grassland transition thickets, and montane grassland.

The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.
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 Fako or by its indigenous name Mongo ma Ndemi. Mount Cameroon is ranked 22nd by topographic isolation.
The Cross–Sanaga–Bioko coastal forests are a tropical moist broadleaf forest ecoregion of west-central Africa. This is a lush forest, rich in flora and birdlife.
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands.
The Cameroon line is a 1,600 km (1,000 mi) long chain of volcanoes that includes islands in the Gulf of Guinea and mountains on the African mainland, from Mount Cameroon on the coast towards Lake Chad on the northeast. They form a natural border between eastern Nigeria and the West Region of Cameroon. The islands, which span the equator, have tropical climates and are home to many unique plant and bird species. The mainland mountain regions are much cooler than the surrounding lowlands, and also contain unique and ecologically important environments.
The Cameroonian Highlands forests, also known as the Cameroon Highlands forests, are a montane tropical moist broadleaf forest ecoregion located on the range of mountains that runs inland from the Gulf of Guinea and forms the border between Cameroon and Nigeria. This is an area of forest and grassland which has become more populous as land is cleared for agriculture.
The wildlife of Cameroon is composed of its flora and fauna. Bordering Nigeria, it is considered one of the wettest parts of Africa and records Africa's second highest concentration of biodiversity. To preserve its wildlife, Cameroon has more than 20 protected reserves comprising national parks, zoos, forest reserves and sanctuaries. The protected areas were first created in the northern region under the colonial administration in 1932; the first two reserves established were Mozogo Gokoro Reserve and the Bénoué Reserve, which was followed by the Waza Reserve on 24 March 1934. The coverage of reserves was initially about 4 percent of the country's area, rising to 12 percent; the administration proposes to cover 30 percent of the land area.
The western greenbul is a species of the bulbul family of passerine birds. It is found in the Cameroonian Highlands forests.
The Cameroon olive pigeon is a species of bird in the family Columbidae. It is found in the Cameroon line, and is found in pasture habitats with minimal vegetation cover as well as in montane forests. Its diet includes fruit from Polyscias fulva and waterberry trees.
The mountain sooty boubou, western boubou or mountain boubou, is a species of bird in the family Malaconotidae.
Ursula's sunbird is a species of bird in the family Nectariniidae restricted to the continental and near-shore portions of the Cameroon line.
The Bioko forest shrew or Isabella's shrew is a species of mammal in the family Soricidae found in Cameroon and Equatorial Guinea. Its natural habitats are subtropical or tropical moist montane forest and subtropical or tropical high-elevation grassland.
Bulbophyllum gravidum is a species of epiphytic plant in the family Orchidaceae that is found in Equatorial Guinea and Cameroon. Its natural habitats are in montane, subtropical or tropical dry forests, at elevations of about 1,500 meters. The Mount Cameroon habitat, in particular, is threatened by the clearing of forest for the purpose of cocoyam farming.
Astropanax barteri is a species of plant in the family Araliaceae.
Astropanax mannii is a species of plant in the family Araliaceae. It is a large evergreen tree native to the highlands of Cameroon, Equatorial Guinea, eastern Nigeria, and São Tomé and Príncipe. Its natural habitat is tropical moist montane forests. It is threatened by habitat loss.
Xylopia africana is a species of plant in the Annonaceae family. It is found in west-central Africa. It is restricted to submontane and lower montane forests. It is threatened due to habitat loss by clearance of forest. It was first described as Melodorum africanum in 1862 by George Bentham.
The Mount Cameroon and Bioko montane forests is a tropical moist broadleaf forest ecoregion in central Africa. It occupies the upper slopes of coastal Mount Cameroon in Cameroon, and the mountains of nearby Bioko island in Equatorial Guinea.
Ilex mitis is a tall, dense, evergreen tree that is indigenous to Sub-Saharan Africa and Madagascar. It makes an excellent fast-growing hedge for gardens - growing tall, straight and dense.
Mount Oku, or Kilum Mountain, is the largest volcano in the Oku Massif, in the Cameroon Volcanic Line, located in the Oku region of the Western High Plateau of Cameroon. It is the second highest mountain in mainland Central Africa. The stratovolcano rises to 3,011 metres (9,879 ft) above sea level, and is cut by a large caldera.
The Rumpi Hills are an undulating mountain range with its highest peak, Mount Rata about 1,800 m (5,900 ft) located between the villages of Dikome Balue and Mofako Balue, Ndian division in the Southwest region of Cameroon. The hills are situated at 4°50’N 9°07’E, cutting across four local councils, with the eastern slopes in Dikome Balue, southern slopes in Ekondo Titi, western slopes in Mundemba, and northern slopes in Toko local councils respectively. These hills are located about 80 km (50 mi) north of Mount Cameroon; about 50 km (31 mi) west of the Bakossi Mountains and some 15 km (9.3 mi) southeast of the Korup National Park.
