The quality of timber is very important in trade and dependable on the purpose of the timber. The article describes the influence of the forest type on the mechanic-technical properties of the timber. The studied properties are weight, the mean breadth of the annual growth rings, and the compression strength.

The percentage of the annual growth rings that is formed during the autumn is characteristic for the compression strength, and it varies accordingly on different forest types. The result from the formula of Janka depends on the forest type.

Being able to classify the timber according its quality makes it possible to have better price for it. it is also important when deciding for what purpose the timber can be used.
