The tropics is a region of the earth surrounding the Equator; it is limited in latitude by the Tropic of Cancer in the northern hemisphere and Tropic of Capricorn in the southern hemisphere. More than 40 percent of the world’s human population lives within the tropical zone.
Tropical Hardwoods shall mean any and all hardwood scientifically classified as angiosperm. Tropical Hardwoods originate from three main continents of Africa (West and Central), Asia and South America. In general tropical forests have more kinds of tree species than any other forest types in the world, around 2,500 species in total. Comparing all the tropical regions of the world the Amazon forests are the richest in plant species with more than one third of all species in the world living in the Amazon.
The tropics of West and Central Africa have the fewest species of trees compared to other tropical regions of the world but even here the diversity in species is high compared to forest types. The Congolian coastal forests are said to be the richest species of the African tropics, moreover the Congo Basin as a whole constitutes the world’s second largest rainforest.
Asian tropical forests are known to be richer in commercial species than tropical forests in other regions of the world because of the dominance of the family “Dipterocarpaceae” therefore tropical forests of Asia give higher yields than the tropics of Africa and South America, the dominance of “Dipterocarpaceae” also implies that the forests are more homogeneous than other tropical forests.
