Dendrology is the study of trees and other woody plants, such as shrubs and woody vines. Dendrologists study every aspect of wooded plants to determine various characteristics of their structural systems.
Dendrology is a specialized approach to studying and identifying over 100,000 different types of trees, and dendrologists study the complex systems of trees to determine evolutionary patterns. Dendrology is also useful for determining economic uses for trees and woody plants. However, dendrology is scientifically limited, because some types of trees and woody plants belong to families that include non-woody species. Dendrology is often classified as a subcategory of botany.
