Gabon, a country along the Atlantic coast of Central Africa, has significant areas of protected parkland. The forested coastal terrain of its famed Loango National Park shelters a diversity of wildlife, from gorillas and hippos to whales. Lopé National Park consists of mostly rainforest. Akanda National Park is known for its mangroves and tidal beaches. Gabon is notable for the Oklo reactor zones, the only known natural nuclear fission reactor on Earth which was active two billion years ago. The site was discovered during uranium mining in the 1970s to supply the French nuclear power industry.
