Harvesting volumes are not sustainable and in the main logging regions lead to exhausting of timber resources.
- The most popular formula for calculation allowable cut level in the main timber production regions suppose logging down all mature, premature and middle age forests in 60 years while logging age there is 100-120 years.
- Economically and in other ways inaccessible forests are taken into consideration while calculating. This increase pressure for accessible forests.
- The current growing stock is rather often overestimated due to inaccuracy of forest survey materials or sometimes even due to “negotiated mistakes”.
