Vegetation : Dense forests are found in these regions. Most of the world’s creepers and climbers are found in these forests. These forests are intensely dense. Due to shedding of leaves in different seasons, these forests are green throughout the year hence these forests are called evergreen forests. Due to the density of trees sunlight does not reach the ground.
Many kinds of trees, are found in this region like Ebony, Mahagony and Rosewood which have very strong wood. Many trees with valuable wood are also found in this region but due to density of forest and geographical restrictions, transportation has not developed therefore the proper use of these resources have not been made.
Temperature and Rainfall : These regions have high temperature throughout the year and also receive heavy rainfall.
Wildlife : These forests have the highest biodiversity in the world. Various kinds of living organisms are found active in this region. Monkeys, Gorilla, various kind of birds, insects, spiders, snakes, bats, lizards, squirrels etc. which live in trees are found in abundance.
