help Niger Delta Swamps FAQ
Are the Niger Delta Swamps all mangrove forest?
No, the delta includes tidal mangroves, freshwater swamp forest, creeks, estuaries, and coastal barrier zones. Salinity and flooding determine which plant communities dominate each part of southern Nigeria.

The dense network of tidal creeks can spread petroleum through mangrove roots, fishing grounds, and community water sources. UNEP documented severe contamination in Ogoniland, including mangrove roots coated with oil residues.

Mangroves and freshwater swamps provide breeding and nursery habitat for fish, shellfish, birds, and mammals. These ecosystems also support the fisheries and farming livelihoods of communities across states such as Bayelsa and Rivers.
How large is the Niger Delta wetland region?
Definitions vary, but the wider delta is commonly described as covering roughly 70,000 square kilometers. It forms one of Africa's largest wetland and mangrove systems along the Gulf of Guinea.
