The forest I saw were not carefully managed in the same way as you would see in England or Germany or France. This is a sparsely populated region that is heavily forested with true forest, not regrowth or planted forest.
Here the tactic has never been to cut out a parcel of land and then regrow it. Clear-cutting or even extensive thinning never happen. So trees that grow and regrow are coming up in the midst of a mature forest canopy -they grow up straight, reaching a height in a short order of time.
The "Forest Management" takes the form of careful selected harvesting that doesn't damage the canopy. Other than that, forests are surprisingly wild.
