When speaking of trees, the crown is the area above the trunk, where succeedingly smaller and smaller branches, stems and twigs form.
The shape of the tree crown helps in identifying the particular kind of tree it is. The size and shape is also used to determine a particular tree's vigor and overall health.
Trees that are taller than their neighboring trees and shrubs are referred to as dominant crowns and receive more light than the plants around them. Trees that can survive on less light are referred to as understory trees
