Forest use means using its produce – timber, undergrowth, plants or their parts for the needs of pharmaceutical industry, cutting trees for Christmas trees, fossil fuel excavation and many more. Foresters made forest products available to the community, provided that the methods employed ensure forest continuity and sustainability.
The volume of timber harvest is specified in forest management plan prescribed for every forest district for the period of 10 years. This plan ensures that the harvested timber does not exceed the production capacity of forests and that the standing timber in forests, the so called stand volume systematically grows. In short, foresters manage forests in a way ensuring its continuity and biological reconstruction.
The volume of timber harvest depends on the so called prescribed cut which is specified in the management plan for every forest. It is the amount of timber that is designed for cutting in particular stands on a particular area and within the 10 years which the plan covers. As the prescribed cut is lower than timber increment within the same period of time, the stand volume increases ( in Poland 55% of timber growth is harvested). It is estimated that the resources of the Polish forests amount to over 2,049 cubic meters of timber.
The harvested timber comes from:
- Final cut – cutting "matured" forest stands, the main purpose is restocking and reconstruction of forest stands,
- Thinning cuts (cleaning and cutting) – removal of undesired trees that are found to be dangerous to the remaining trees and valuable elements of stands,
- Not-planned cut – as a result of natural disasters occurring in forests.
Types of forest utilization:
- Main utilization, that is timber harvest,
- Other utilization – harvest of undergrowth, forest fruit, seeds, etc.
