This subject provides students with advanced concepts in wood quality, the origin and cause of wood defects, their distribution in the tree and impact on wood properties. Wood quality attributes are defined together with a description of the systematic variation of wood properties within and between trees. Students will develop an understanding of wood as a complex material and factors responsible for its characteristics including density, moisture content, shrinkage and swelling. Students are given an in depth knowledge of the impact of environmental and genetic manipulation of wood quality attributes; how silvicultural techniques can be used to manage wood quality in softwood and hardwood plantations and the concepts of managing forests to end-user requirements. Students are introduced to quality surveys of forests, commercial techniques for measuring quality and log grading.

On completion of this subject students should have a practical knowledge of:

• The important wood quality attributes and how they vary within and between trees
• Defects that arise in the tree and how they are measured
• Forest management systems and how they can influence wood quality and the impact of wood quality on solid wood processing
• Derive equations for basic, oven-dry, air dry and green density of wood, wood moisture content, void volume and percentage saturation, and apply laboratory method for their determination.
• Understand the elements of undertaking a wood quality survey.

Completion of an assignment on wood quality, involving either a literature review or laboratory research project.
