Landscape maintenance is also one of the tasks of agriculture. For example, trees that have been attacked by the bark beetle and have died must be felled. The dead trees have red dried needles and in some cases the bark has already burst open. The bark beetles eat away at the thin water veins between the bark and the trunk and thus prevent the tree from being supplied with food and liquid. Since the brood of a female bark beetle can produce up to 100,000 offspring, it is important, to remove the infested trees from the forest. This will at least reduce, if not completely prevent, infestation of additional trees.
The trees infested by bark beetles must first be cut down...
...and then be taken away.
