päälälohkoon

Päälälohkoon is a Finnish term that translates directly to "into the head block" or "to the head section." It is primarily used in the context of lumber and forestry to refer to the section of a log that is closest to the tree's crown. This portion of the log is often characterized by its smaller diameter and the presence of branches, which can lead to more knots and irregular grain patterns compared to the butt log.

The päälälohkoon is generally considered to be of lower value for timber production than the butt log or middle sections. Its properties make it less suitable for high-quality lumber, furniture, or structural applications. However, it can still be utilized for pulpwood, firewood, or for the production of smaller wood products. The quality and usability of the päälälohkoon can vary significantly depending on the species of tree, its age, and how it was felled and processed. Foresters and lumberjacks are trained to identify and separate different log sections, including the päälälohkoon, to optimize timber use and value.
