There are three major types of forests- tropical, temperate and boreal forests. Forest profile: There are different kinds of plants of varied height and size in the forests. Parts of a tree above the stem, including the branches and leaves are collectively known as the Crown . Trees belonging to the genus Pinus have tapered crowns, while a neem tree has a Crown that looks like a globe. Depending on the height of trees and the types of animals that live there, forests are divided into layers. Emergent layer: The branches on the topmost layer of the tallest trees are known as the emergent layer. This layer is at a height of 40 m from the ground and receives sunlight in abundance. Eagles, butterflies, bats and certain types of monkeys live here Canopy layer: Below the emergent layer is the canopy la...
