This course is designed to enable students to practice identification methods. Let students understand tree growth and wood formation. Observe the macroscopic and microanatomical structures of broadleaf and coniferous wood. The students need to draw the wood cell type, organization and variation, and then discuss the concept and meaning of wood quality. In addition, students will be able to observe and distinguish the commercial wood from various countries and Taiwan. We hope that students can learn the ability of wood identification in this course. They will make the best use of wood according to its nature.
