We use the forest in many different ways: as a sports area for mountain biking, for recreation during walks, as a playground for school trips or as a pantry for mushroom hunting. Above all, however, we use the forest as a supplier of a highly sought-after raw material: wood. Much of this wood is processed.
Think about it and count: how many wooden objects have you come into contact with today?
Approximately 70 million solid cubic metres of wood are ‘harvested’ in Germany every year. However, at least the same amount grows back in the forests every year. The cubic metre (abbreviation: Fm) is the most commonly used unit of measurement for wood. One cubic metre corresponds exactly to a cube with 1m x 1m x 1m of solid wood mass. However, logs are not cubes, so they have to be measured differently. The length of the trunk is measured with a tape measure and the diameter in the middle with a caliper. Foresters write the measurements on the base of the trunk. The forester ‘records the wood’, i.e. he or she types the measurements into a tablet, which then calculates the volume of the trunk in Fm.
