Using an Economic Enterprise to Calculating Damage to Forest wood product following selective logging

Selective cutting in mature hardwood stands of Caspian forests often causes physical damage to residual trees through logging operations resulting in a decline in bole quality and subsequent loss of tree value. This study uses an economic valuation method by opportunity and replacement cost approaches. In the study area, a total density of 5.1 trees/ha and 17.3 m 3 /ha of wood was harvested. The damage to trees sustained along skid trails was found to be significantly more than the damage incurred along in logging gaps and winching areas. The results of using replacement and opportunity cost methods showed that selective cutting can damage residual trees 1402.42 and 45966.83US$ in the region. On the other hand, the selective logging can cause damage as much as US$303.65 per hectare. The results suggest that logging operation also need to be accompanied by a close supervision of field personnel and post logging site inspections to be implemented properly.
