Why are mangrove swamps an important part of the ecosystem of west africa?

These mangroves flank the coastline of western and central Africa, in suitable low energy marine environments. The largest mangrove stand is found in the Niger Delta, which supports the most extensive area of mangrove in Africa. The mangroves of this region have no endemic species but support some endangered species, such as manatees and perhaps pygmy hippopotamuses in the Niger Delta. Mangroves are important as nursery and feeding areas for marine fishes, and they trap large amounts of sediment. The oil industry, clearance for salt pans, and overcutting by an increasing human population pose serious threats to these mangroves, but some are contained within protected areas.
