Campo Ma'an National Park: Cameroon's Atlantic Biafran Forest Protected Landscape

Campo Ma'an is especially renowned for its populations of critically endangered western lowland gorillas and endangered central chimpanzees, which the IUCN has identified as priority species for conservation in this landscape. The park hosts an ongoing gorilla habituation project and employs local Bagyeli trackers in great ape conservation initiatives. Beyond the primates, the park protects significant populations of forest elephants, mandrills, leopards, and forest buffalo. The area is also recognized as one of 33 Important Bird Areas in southwestern Cameroon with more than 300 bird species recorded.

The conservation history of Campo Ma'an reflects the evolution of forest protection in Cameroon from early colonial-era reserves to modern national park status. The original Campo Wildlife Reserve was established in 1932 through an agreement between the Government of Cameroon and the Campo Forest Company, covering approximately 1,582 km². This early designation reflected colonial interests in managing forest resources while allowing controlled exploitation. In 1980, the adjacent Ma'an forest plantation covering 990 km² was created specifically for conservation of the okoumé tree species (Aucoumea klaineana), a commercially valuable timber species. On August 6, 1999, under Decision 054/CAB/PN, the forest was elevated to a Technical Operational Unit spanning 771,000 hectares, incorporating protected areas, forest management units, maritime estate, and agroforestry zones. The formal establishment of Campo Ma'an National Park in 2000 represented the culmination of these conservation designations while also serving as environmental compensation for the Chad-Cameroon oil pipeline project. The signing of the Campo Ma'an GEF/Biodiversity Project in December 1999 introduced new funding and enforcement mechanisms, including the creation of an Integral Protection Zone covering 2,901 km² completely off-limits to local communities, with natural resource extraction prohibited throughout 4,196 km² of the broader region.

The physical landscape of Campo Ma'an National Park is characterized by Atlantic Biafran forest, a closed evergreen canopy ecosystem that covers the majority of the protected area. The terrain consists largely of lowland tropical rainforest with the Caesalpiniaceae plant family playing a dominant role in the forest composition. The park extends from the coastal zone along the Atlantic Ocean inland through undulating terrain typical of the Central African plateau. The region has maintained tropical rainforest continuity since the Pleistocene era, evidenced by the distribution of slowly dispersing plant species and high degrees of endemism. The forest ecosystem transitions through various habitat types as elevation changes occur, though the overall character remains one of dense, species-rich evergreen forest with a multi-layered canopy. The park's location near the coast also incorporates elements of maritime influence on the broader landscape character.

The ecological character of Campo Ma'an centers on its status as a biodiversity hotspot within the Atlantic Biafran forest ecoregion. The park contains remarkable plant diversity with 256 documented plant species, including 29 species occurring exclusively within park boundaries and 22 listed as endangered by the IUCN. A rare and critically endangered orchid from the genus Distylodon was discovered in a nearby village, with ongoing assessments seeking additional occurrences within the protected area. The forest type is described as closed evergreen canopy, dominated by species in the Caesalpiniaceae family. The park's ecological significance is amplified by its ancient forest heritage, as the region is believed to have remained continuously forested as tropical rainforest throughout the Pleistocene, providing critical refugia for species with limited dispersal capabilities. The bi-modal rainfall pattern with two dry and two wet seasons annually shapes the ecological dynamics of the ecosystem, influencing vegetation cycles, wildlife activity patterns, and the overall productivity of this forest environment.

Campo Ma'an supports exceptional wildlife diversity across multiple taxonomic groups. The park is particularly significant for its populations of critically endangered western lowland gorillas and endangered central chimpanzees, both identified as priority species by the IUCN for conservation action. A gorilla habituation program is underway, with 15 Bagyeli community members employed as guides and trackers supporting great ape conservation. Large mammals include forest elephants, African forest buffalo in the southern area, hippos, bush pigs, and various antelope species including Peters's duiker. Predators are represented by leopards, while primate diversity includes black colobus and mandrills. The park supports a remarkable 122 reptile species and 165 fish species. Avifauna includes more than 300 bird species, earning the park recognition as one of 33 Important Bird Areas in southwestern Cameroon. A 2015 millipede survey documented 27 species, with Aporresmus gabonicus being the most abundant. The presence of giant pangolins highlights the park's importance for specialized forest fauna.

Campo Ma'an holds significant conservation importance as a priority landscape for western lowland gorilla and central chimpanzee conservation according to the IUCN. The park's establishment in 2000 as a biodiversity compensation for the Chad-Cameroon oil pipeline reflects its role in broader environmental mitigation strategies. The area receives support through the Global Environmental Facility and the World Bank Biodiversity Conservation and Management Project. Conservation challenges include logging activities, poaching, agricultural expansion, and coastal development pressures. Construction of the Memve'ele hydroelectric dam and the Kribi deep-sea port represent emerging threats to regional biodiversity. Between 2011 and 2014, human hunting pressure reportedly declined by 50 percent, though illegal hunting and poaching continue within the reserve. A formal co-management agreement has been signed with the Bagyeli indigenous community, integrating local knowledge and participation into conservation management. The park is proposed as a pilot ecotourism site to support sustainable conservation financing while providing economic benefits to surrounding communities.

The Campo Ma'an region is the traditional territory of indigenous groups with deep historical roots in the area. The Bagyeli, sometimes referred to as Bagyeli Pygmies, represent a minority population of fewer than 10,000 people who have traditionally practiced subsistence hunting and gathering, relying on the forest for resources including medicinal plants. Various Bantu groups including the Batanga, Mabea, Yassa, Ntumu, Mavae, and Bulu also inhabit the region, with coastal groups primarily engaged in fishing while inland groups practice subsistence agriculture. A third ethnic group, the Bebilis originating from eastern Cameroon, also reside in the area, maintaining hunting camp lifestyles similar to the Bagyeli. The establishment of the Integral Protection Zone in 1999 introduced restrictions on natural resource access that have created tensions with local communities, including incidents involving the destruction of hunting camps and pirogues by eco-guards. A formal co-management agreement with the Bagyeli has been established, and employment of Bagyeli community members as conservation guides represents an effort to integrate indigenous knowledge and sustainable livelihoods into park management.

Campo Ma'an National Park stands as one of Cameroon's largest and most biodiverse protected areas, encompassing critical habitat for western lowland gorillas and central chimpanzees in the Atlantic Biafran forest ecosystem. The park's unique combination of coastal and interior forest environments supports exceptional species richness, including forest elephants, mandrills, leopards, and over 300 bird species. The ongoing gorilla habituation project offers rare opportunities for wildlife observation while the integration of Bagyeli indigenous communities into conservation management provides a model for collaborative protected area governance. The park's establishment history as environmental compensation for oil infrastructure development reflects modern approaches to biodiversity offsets, while its proposed development as an ecotourism destination aims to create sustainable financing for long-term conservation.

The climate of Campo Ma'an follows a bi-modal pattern with two dry seasons occurring from November to March and July to August, while two rainy seasons span April to June and August to October. The average temperature remains around 25°C year-round. The optimal visiting period generally corresponds to the drier seasons when wildlife viewing conditions improve as animals congregate more readily around remaining water sources and vegetation density decreases slightly. However, the park's evergreen character means that forest landscapes remain lush throughout the year. Visitors interested in primate habituation experiences should consider that the dry seasons may offer more consistent tracking opportunities, though the wet seasons provide their own ecological rewards with active understory vegetation and bird activity.
