The mangrove swamp in Nigeria is restricted to the tropical rainforest. The mangrove swamps are found in the coastal regions of Nigeria and are characterized by the presence of mangrove trees. These trees are adapted to live in the brackish waters of the coastal regions, where saltwater and freshwater mix. The tropical rainforest region of Nigeria is located in the southern part of the country, along the coast. It is characterized by high rainfall and dense vegetation, including the mangrove trees in the coastal areas. The other regions mentioned - Sahel savanna, Sudan savanna, and Guinea savanna - are all located in the northern part of Nigeria and are characterized by grasslands, trees, and shrubs adapted to the drier conditions of the region.
