Guinée Maritime, also called Basse Guinée, covers about 18% of the country and includes roughly 300 kilometres of Atlantic coast, mangroves, estuaries, mudflats and islands. Moyenne Guinée, or Fouta Djallon, covers about 22% and consists of highlands, plateaus, waterfalls and important headwaters. Haute Guinée covers about 40% and contains Sudanian-Guinean savanna along river systems such as the Niger, Milo, Sankarani and Tinkisso. Guinée Forestière covers about 20% and includes humid forests such as Ziama, Diecké and Mount Nimba. Elevation ranges from sea level to Mount Nimba at 1,752 metres, and the highlands provide the sources of more than 22 major West African rivers. Guinea's protected-area system includes national parks, classified forests, managed nature reserves, marine and coastal sites and community conservation areas. The World Database on Protected Areas recorded 132 protected areas in September 2026; 18 had a management-effectiveness evaluation and no other effective area-based conservation measure was recorded. UNESCO biosphere reserves include Badiar, Haut Niger, Massif du Ziama and Mount Nimba. The Mount Nimba Strict Nature Reserve is a World Heritage property shared with Côte d'Ivoire, with about 12,540 hectares in Guinea; it has been on the List of World Heritage in Danger since 1992. CEGENS coordinates the Mount Nimba-Simandou area, while the national parks and reserves agency OGUIPAR manages parks and reserves. The Ministry of Environment and Sustainable Development, known as MEDD, leads national environmental policy, and the forest service DNEF handles forests, fire prevention, fauna and biodiversity awareness. Guinea's ecosystems support agriculture, grazing, rice, cassava, maize, fonio, coffee, cocoa, kola, hunting, inland and marine fishing, mangrove wood, salt and other forest products. Mangroves provide fish, crab and mollusc nursery habitat, coastal protection and income. Protected-area core zones can impose strong limits on resource use, while buffer and transition zones may permit regulated or community-based use. Species of conservation concern include the endemic and critically endangered Mount Nimba viviparous toad, the threatened Lamotte's shrew, the West African chimpanzee, elephants, lions, leopards, manatees, Derby eland and several marine turtles. Ziama contains more than 1,300 plant species, 124 mammal species, 286 bird species, 54 reptile species and 30 amphibian species. Guinea has 16 Ramsar wetlands covering about 9,065,446 hectares, including coastal, mangrove and Upper Niger sites. The main pressures are bush fires, slash-and-burn cultivation, hunting, grazing, logging, charcoal production, mining, pesticide runoff, overfishing and illegal fishing. These pressures can fragment habitats, cause erosion and sedimentation, alter springs and river flows, damage mangroves and pollute water. Mining around Mount Nimba and Simandou requires particular scrutiny: UNESCO reported in 2025 that new exploration or extraction licences in or around the property should not proceed without cumulative environmental and social impact assessments, strategic environmental assessment and IUCN review. Under Guinea's Environmental Code L/2019/0034/AN, people can request available environmental information, participate in environmentally relevant decisions and seek environmental justice where they are affected. Protected-area classification follows a decree after a public inquiry, and local communities participate in classification and management. Hunting and capture require the relevant permit or licence, and protected species cannot normally be hunted, captured, collected, held or exported. Access, visitor charges and booking arrangements for parks and reserves are not nationally uniform, so the responsible local administration, OGUIPAR or CEGENS should be checked for the specific site.
Nature in Guinea
Guinea contains four natural regions, from Atlantic mangroves and estuaries to Fouta Djallon highlands, savanna and humid forests. These landscapes regulate water, support fisheries and farming, protect soils and coastlines, store carbon and provide habitat for rare species. Nature protection exists through national parks, classified forests, reserves, wetlands and community-managed areas, but management and access vary strongly by site.
Tip
Treat nature-related plans in Guinea as site-specific decisions: the right access, permit and responsible body can change between a park, classified forest, wetland, mangrove or community-managed area. Check the site's management status and current local conditions before travelling, harvesting, hunting, fishing or starting a project. Give extra scrutiny to activities that could affect protected species, water systems, mangroves or Mount Nimba and Simandou.
