List of ecoregions in Nigeria

The biogeographic regionalization of Earth's terrestrial biodiversity, known as Terrestrial Ecoregions of the World (TEOW), is made up of 867 ecoregions that are divided into 14 biomes. In addition to offering a comprehensive map of terrestrial biodiversity, TEOW also provides a global species database for ecological analyses and priority setting, a logical biogeographic framework for large-scale conservation strategies, a map for enhancing biogeographic literacy, and a foundation for the Global 200.^[1][2]

Similarly, another author indicated that there are 14 distinct biomes, including forests, grasslands, and deserts, among the 846 ecoregions that make up the area. Ecoregions vary in size; the island group of St. Peter and St. Paul Rocks in the Atlantic Ocean is only 6 km² (2.3 sq mi), while the East Siberian Taiga is 39,000,000 km² (15,000,000 sq mi).^[3]
