Cameroon Coastal Forests are a biodiverse ecoregion on the Gulf of Guinea coast encompassing lowland rainforests, mangroves, and offshore islands. Centered along the littoral provinces of Cameroon, the ecoregion connects to larger Central African biomes associated with Cross-Sanaga-Bioko coastal forests, Gabonian lowland systems and the Gulf of Guinea island arc including Bioko and Annobón. Historically surveyed by naturalists associated with institutions such as the Royal Botanic Gardens, Kew, Muséum national d'Histoire naturelle and the Smithsonian Institution, the region has been the subject of international conservation efforts by organizations like World Wide Fund for Nature, IUCN and the Critical Ecosystem Partnership Fund.
The ecoregion occupies coastal plains, river deltas and small islands stretching from the Niger Delta flank through the Rio Muni coastline into southwestern Cameroon around the Sanaga River estuary. Influenced by maritime currents of the Gulf of Guinea and historical biogeographic barriers such as the Cameroon Line, the forests host endemics that link to West African centers of endemism recognized by scholars at University of Cambridge, Harvard University and University of Yaoundé I. Early botanical exploration by figures associated with the Cameroon Highlands expeditions contributed to baseline inventories used by conservation agencies including BirdLife International, Conservation International and the African Wildlife Foundation.
Terrain is predominantly lowland with elevations generally below 300 m, punctuated by inselbergs and volcanic features tied to the Cameroon Volcanic Line. Major hydrological systems include the Mungo River, Nkam River and the Wouri River estuary. Coastal habitats alternate between dense evergreen forest, swamp forest and tidal mangroves along the Duala Basin and around island groups such as Bioko and Corisco. Climate is equatorial-monsoonal with a long rainy season influenced by the Intertropical Convergence Zone and shorter dry spells modulated by the Harmattan. Meteorological monitoring by agencies like Meteo France, NOAA and the African Centre of Meteorological Applications for Development document high mean annual rainfall and consistent temperatures that sustain the evergreen canopy.
Floristic composition features families prominent in West and Central African rainforests, including Fabaceae, Malvaceae, Meliaceae, Rubiaceae and Arecaceae. Notable tree genera recorded by herbaria at Kew and National Herbarium of Cameroon include Entandrophragma, Terminalia and Pterocarpus. Understory and climbers host species described in monographs from Royal Botanic Gardens, Kew and the Missouri Botanical Garden. Faunal assemblages include primates such as the Nigeria-Cameroon chimpanzee, Preuss's red colobus, Drill and populations of Western gorilla linked by genetic studies from University College London and Max Planck Institute for Evolutionary Anthropology. Avifauna of conservation concern features taxa monitored by BirdLife International and Wetlands International, while herpetofauna and invertebrates are documented in surveys by Zoological Society of London and regional universities. Marine and estuarine life around the coast include seagrass beds studied by institutes such as the Scripps Institution of Oceanography and fisheries monitored by the Food and Agriculture Organization.
The coastal zone is inhabited by ethnic groups including the Bakoko, Bassa, Duala, Bamiléké migrants, and Pygmy groups historically associated with forest economies. Colonial histories involving Germany (1871–1918) and mandates under League of Nations and United Nations Trusteeship Council shaped land tenure and labor patterns studied by historians at University of Oxford and Université de Yaoundé II. Contemporary livelihoods revolve around agroforestry, cocoa and oil palm cultivated by companies such as Societé Camerounaise de Palmeraies and artisanal fisheries supplying markets in Douala and regional trade routes linked to ports like Port of Douala. Social research by United Nations Development Programme, African Development Bank and NGOs such as Oxfam examine poverty indices, customary rights and demographic trends.
Primary threats derive from large-scale industrial agriculture (notably cocoa and Elaeis guineensis plantations), logging concessions held by multinational firms, urban expansion of Douala, infrastructure projects linked to corridors financed by institutions such as the World Bank and biodiversity loss driven by hunting for bushmeat traded in markets studied by TRAFFIC and Fauna & Flora International. Climate change modeled by the Intergovernmental Panel on Climate Change and regional impacts reported by African Union agencies exacerbate sea-level rise, mangrove dieback and altered rainfall regimes. Conservation responses coordinated by IUCN, WWF, Conservation International and local NGOs aim to reconcile industrial development with measures promoted under conventions like the Convention on Biological Diversity and the Ramsar Convention.
Protected areas include national parks, forest reserves and community-managed forests recognized by Cameroon’s Ministry of Forestry and Wildlife alongside transboundary initiatives. Sites comparable to protections advocated at IUCN World Conservation Congress and pilot projects funded by the Global Environment Facility support management planning, capacity building and law enforcement partnerships with agencies such as Cameroon Ministry of Environment and Nature Protection and park authorities advised by Wildlife Conservation Society. Collaborative models with customary authorities and international donors reflect precedents from Kakum National Park partnerships and landscape-scale programs led by African Parks.
Long-term research programs are conducted by universities and research centers including IRAD (Institute of Agronomic Research for Development), University of Yaoundé, University of Douala, Kew Gardens and international partners like Smithsonian Institution. Monitoring employs remote sensing platforms from NASA, European Space Agency and field surveys coordinated with conservation NGOs and citizen science initiatives comparable to projects by Global Forest Watch and iNaturalist. Taxonomic studies, population genetics and ecological modeling published through outlets affiliated with Royal Society and PLOS inform adaptive management and policy discussions at meetings convened by bodies such as the African Ministerial Conference on the Environment.
