Debarking is the process of removing bark from wood. Traditional debarking is conducted in order to create a fence post or fence stake which would then go on to be pointed before being planted. [ 1 ] Debarking can occur naturally during powerful tornadoes .
A hydraulic debarker is a machine removing bark from wooden logs by the use of water under a pressure of 700 kilopascals (100 pounds per square inch) or greater. [1] Hydraulic debarking can reduce soil and rock content of bark, but may increase the water content.

International Standards For Phytosanitary Measures No. 15 (ISPM 15) is an International Phytosanitary Measure developed by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries.
Debarking removes bark from the logs. Decking is the process for sorting the logs by species, size and end use (lumber, plywood, chips). A sawyer uses a head saw (also called head rig or primary saw) to break the log into cants (unfinished logs to be further processed) and flitches (unfinished planks).
In use, the sharpened edge is slid between the bark and the wood, removing the bark from the tree in a number of strips. It is especially useful at removing bark without damaging the wood below the bark.
Like all vascular plants, trees use two vascular tissues for transportation of water and nutrients: the xylem (also known as the wood) and the phloem (the innermost layer of the bark). Girdling results in the removal of the phloem, and death occurs from the inability of the leaves to transport sugars (primarily sucrose) to the roots.
Using a drawknife in making a flatbow. A drawknife is commonly used to remove large slices of wood for flat faceted work, to debark trees, or to create roughly rounded or cylindrical billets for further work on a lathe, or it can shave like a spokeshave plane, where finer finishing is less of concern than a rapid result.
The preparation process involved felling, debarking, and often, curing for several months to ensure the material's durability. Specialized tools made from shell, stone, or later iron, were used to cut and shape the timber. This wood was primarily used in the construction of structural elements like posts, beams, and rafters.
