List of ecoregions in Nigeria

Last updated

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.

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, while the East Siberian Taiga is 39 million km2. [3]

The following is a list of ecoregions in Nigeria, according to the Worldwide Fund for Nature.

An ecoregion is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation . Ecoregions are also known as "ecozones", although that term may also refer to biogeographic realms.

The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.

The Afrotropical realm is one of the Earth's eight biogeographic realms. It includes Sub-Saharan Africa, the southern Arabian Peninsula, the island of Madagascar, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region.

The Northern Congolian forest–savanna mosaic is a forest and savanna ecoregion of central Africa. It extends east and west across central Africa, covering parts of Cameroon, Central African Republic, Democratic Republic of the Congo, South Sudan, and Uganda. It is part of the belt of transitional forest-savanna mosaic that lie between Africa's moist equatorial Guineo-Congolian forests and the tropical dry forests, savannas, and grasslands to the north and south.
