| Course objective : | The students will develop a knowledge of wood characteristics including properties and defects. After completing the course the student is expected to assess wood quality by means of suitable techniques such as measurements, grading and other tests argue consequences of silviculture options on wood characteristics (spruce) recognize the most common temperate species from a wood sample. |
