Tropical rainforests have existed on earth for hundreds of millions of years. Most tropical rainforests today are on fragments of the Mesozoic era supercontinent of Gondwana. [13] The separation of the landmass resulted in a great loss of amphibian diversity while at the same time the drier climate spurred the diversification of reptiles. [10]
Tropical African forest is 18 percent of the world's total and covers over 3.6 million square kilometers of land in West, East, and Central Africa. This total area can be subdivided to 2.69 million square kilometers (74%) in Central Africa, 680,000 square kilometers (19%) in West Africa, and 250,000 square kilometers (7%) in East Africa . [ 6 ]
Threats to the rainforests include destruction and fragmentation of forests by commercial logging, oil palm plantations, and mining. The bushmeat trade and poaching is depleting the rainforests of wildlife. [2] With annual forest loss of 0.3% during the 2000s, [5] the region had the lowest deforestation rate of any major tropical forest zone. [6]
[48] [49] [50] Almost 90% of West Africa's rainforest has been destroyed. [51] Since the arrival of humans, Madagascar has lost two thirds of its original rainforest. [52] At present rates, tropical rainforests in Indonesia would be logged out in 10 years and Papua New Guinea in 13 to 16 years. [53]
Ituri Rainforest. The Congo Basin is the largest forest in Africa. More than 10,000 plant species can be found in and around the forest. [10] The humid forests cover 1.6 million km². [4] The Congo Basin is an important source of African teak, used for building furniture and flooring. An estimated 40 million people depend on these woodlands ...
The Nigerian lowland forests, also known as the Nigerian rainforest, are 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.
The Republic of the Congo is home to approximately 10,000 species of tropical plants. Among which thirty percent (3,000) of these species are specific to Congo. Congo plants include some of the most diverse and rich environments and the largest forest areas, with only the Democratic Republic of the Congo being more diverse. There are about ...
The Guineo-Congolian region is a tropical, lowland rain forest area, typified by the forests of the Congo Basin. The terrain is generally under 1,000 m (3,300 ft) and the annual rainfall is typically in the range 1,600 to 2,000 mm (63 to 79 in). [ 1 ]
