Nigerian Lowland Forests
The Nigerian lowland forests is a tropical moist forest ecoregion in southwestern Nigeria and southeastern Benin. The ecoregion is densely populated, and home to several large cities including Lagos, Ibadan, and Benin City. There is still significant tree cover, but the remaining enclaves of forest are increasingly fragmented. The ecoregion is wetter along the coast and drier inland, resulting in bands of vegetation zones that run parallel to the coast for the 400 km length of the region. Geography The Nigerian lowland forests are bounded on the south by coastal mangroves and the Gulf of Guinea, on the east by the Niger River and its delta, on the north by the Guinean forest-savanna mosaic. On the west it is bounded by the Dahomey Gap, a drier coastal region where forest-savanna mosaic extends all the way to the ocean, separating the Lower Guinean forests, of which the Nigerian lowland forests are part, from the Upper Guinean forests of West Africa."Nigerian lowland forests".

Benin City
Benin City is the capital and largest city of Edo State, Edo State, Nigeria. It is the fourth-largest city in Nigeria according to the 2006 census, after Lagos, Kano (city), Kano, and Ibadan, with a population estimate of about 3,500,000 as of 2022.

Lower Guinean Forests
The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Lower Guinean forests from the Upper Guinean forests to the west, which extend along the western coast of the Gulf of Guinea from Togo to Liberia and north to Guinea. To the north and northeast, the Lower Guinean forests transition to the drier inland Guinean forest–savanna mosaic and Northern Congolian forest–savanna mosaic and to the southeast by the Congolian Coastal forests, whose boundary is the Sanaga River in Cameroon.Linder, H.

Guarea
''Guarea'' is a genus of evergreen trees or shrubs in the family Meliaceae, native to tropical Africa and Central and South America. At their largest, they are large trees 20–45 m tall, with a trunk over 1 m diameter, often buttressed at the base. The leaves are pinnate, with 4–6 pairs of leaflets, the terminal leaflet present.

Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus (''Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Savanna Climate With Dry-winter Characteristics
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
