Study Notes
Introduction to Dendrology
- Dendrology is a scientific and artificial word derived from two Greek words meaning "trees" and "discourse or study".
- The term was first used in 1668 by Ulisse Aldrovandi, an Italian physician and naturalist, as the title of a book on trees.
Definition and Scope of Dendrology
- Dendrology is a division of forestry or botany that treats of the taxonomy of trees and other woody plants.
- It includes the study of nomenclature, classification, identification, and distribution of trees.
- In some universities, dendrology is taught by a professor of forestry, while in others it is taught by a professor of botany who specializes in taxonomy or systematic botany.
Importance of Dendrology
- The study of dendrology has five principal objectives: nomenclature of trees, classification of trees, identification of trees, and distribution of trees.
- Tropical dendrology is a distinct field of study that focuses on the taxonomy of tropical trees, which are different from those found in temperate regions.
Objectives of Dendrology
- Nomenclature of trees: learn scientific names, common names, and the code of botanical nomenclature.
- Classification of trees: learn how trees are classified into families, genera, and other groups according to their arrangements.
- Identification of trees: learn how to identify unknown trees using keys, manuals, floras, and herbaria.
- Distribution of trees: learn how trees are distributed into climatic zones and forest types.
What is a Tree?
- A tree is a woody plant with a well-defined, erect, perennial trunk and a more or less definitely formed crown, typically attaining a height of at least 12 to 15 feet (4 to 5 m) and a trunk diameter of 7 to 10 cm (1.3 m).
- Shrubs are perennial woody plants smaller than trees, usually with several perennial stems branched from the base.
- Herbs are plants with herbaceous or soft stems, annual or perennial.
