A clearcut in the Mazurians was recultivated with scotchpine (Pinus silvestris) only. It now forms a five years old thicking. The coming trees are protected against fraying with helix-shaped strips that keep on the stem by means of their own tension. These strips strangle the fast growing stems because the do not wind out according to the radial increment of the stems.
