Tree identification and anatomy

Tree identification and anatomy

Tree Identification

  • Grasp the importance of tree identification in the context of Forestry and Arboriculture.

  • Comprehend that trees can be classified into two main types: deciduous (those that lose their leaves annually) and evergreen (those that retain their leaves year-round).

  • Understand common identifiers such as leaf shape, bark texture, tree shape, fruit, flower type and location. These help determine the species of a tree.

  • Get familiar with the use of dichotomous keys for precise tree identification.

Anatomy of Trees

  • Learn the basic parts of a tree: the roots, trunk, branches, twigs, and leaves.

  • Grasp the crucial role of the root system in anchoring the tree and absorbing water and nutrients from the soil.

  • Understand the trunk is composed of four layers: the inner bark (phloem), cambium, sapwood, and heartwood.

  • Appreciate the purpose of the branches and twigs in providing support for leaves, flowers, and fruits, and also in conducting water and nutrients.

  • Understand the importance of leaves in photosynthesis. Leaf structures such as the blade, petiole, and the arrangement of veins can also aid in tree identification.

Tree Growth and Development

  • Understand the tree growth process, including cell division in the cambium, sapwood’s role as active xylem to transport water, and the heartwood’s role as a structural centre.

  • Learn about the influence of environmental factors such as light, water availability, and temperature on tree growth.

  • Understand the concept of annual growth rings. Each ring typically represents one year of growth and can be used to estimate a tree’s age.

Tree Health and Disease

  • Understand common signs of tree health issues, including discolouration, defoliation, growths, and deformities.

  • Learn about the common pests and diseases which affect trees, from fungal infections to insect invasions.

  • Understand the role of tree inspection in spotting early signs of health issues or structural problems.

  • Recognise the necessity of regular maintenance and prevention methods such as pruning, fertilizing, and watering.

These points can serve as a base for further research or a quick refresher for key aspects needed in Basic Tree Survey and Inspection. Remember, hands-on experience and observation are also invaluable in mastering these skills.
