Mount Cameroon and Bioko montane forests

The Mount Cameroon and Bioko montane forests is a tropical and subtropical moist broadleaf forests ecoregion located in the Afrotropic biogeographic realm, covering sub-Saharan Africa and the southern Arabian Peninsula, spanning approximately 1,141.1 km². Classified under the WWF ecoregion code AT0121, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences warm year-round with high annual rainfall, typically exceeding 2,000 mm. The dominant vegetation consists of dense, multi-layered canopy of broadleaf evergreen trees. These conditions create the foundation for the ecological communities found within the Mount Cameroon and Bioko montane forests.

Ecological Significance

These forests are the most biodiverse terrestrial ecosystems on Earth, hosting an extraordinary density of plant and animal species per unit area. Epiphytes, lianas, and a rich understorey characterise the complex vertical structure. The Mount Cameroon and Bioko montane forests contributes to the broader biodiversity patterns of the Afrotropic realm.

Geographic Distribution

The Mount Cameroon and Bioko montane forests extends entirely within Cameroon. This geographic range places it within the Afrotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Mount Cameroon and Bioko montane forests supports a range of wildlife, including African Blackwood (Dalbergia melanoxylon), African Oil Bean (Pentaclethra macrophylla), African Pearwood (Baillonella toxisperma), African Teak (Milicia excelsa), Akume (Guibourtia tessmannii), Allspice (Pimenta dioica), alstonia (Alstonia boonei), Anil de pasto (Indigofera suffruticosa), and 42 more species. Among these, 4 species are classified as threatened on the IUCN Red List, underscoring the conservation importance of this ecoregion.

Conservation

Like many tropical and subtropical moist broadleaf forests ecosystems, the Mount Cameroon and Bioko montane forests faces threats from deforestation, agricultural expansion, logging, and climate change. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
