Technique and planning

Many technical aspects need to be taken into account when working in the forest. An important one of which is the technology used in the forest during timber harvesting. At the same time immense progress is being made in forest planning. Remote sensing and new methods of inventory taking are leading to new methods of analysis. Forest enterprises as well as society as a whole must learn to cope with natural hazards. Sometimes the forest itself constitutes an object in need of protection.
