Wood feature
As wood features all the properties are referred to which the individual shape of wooden describe. They form during natural wood growth. Most characteristics are tree species specific, others can be created or influenced by the environment.
Causes of wood features
The wood characteristics include the shape of the trunk, the growth habit, the wood color, the formation of the bark , as well as the distribution and characteristics of the branches (knots). External influences of various wood pests such as insects and fungi, reactions of the tree to external influences (e.g. reaction wood and ingrowns), effects of the weather such as wind breakage or frost damage can shape the wood characteristics as well as human intervention and damage.
Wood processing
In wood processing, some wood features can have a negative effect, they limit the use for certain applications and are referred to as wood defects . In addition to various types of damage to the wood, a number of natural features that are based on the structure of the tree can also be disadvantageous for further processing. In individual cases, however, certain wood features can also open up further possible uses and thus represent an increase in the value of the wood. For example, woods with burl bulbs are in demand for their appearance for veneer production or for turning. So-called crooked timber (logs with crooked or curved growth) often find a particular use in shipbuilding or for stair stringers used.
