Economic valuation of damages to residual trees due to logging operations in Chafroud ‎Forests of Guilan province

The aim of this research was the introducing a method to convert technical data of logging operation damages to economic value to express the investment for improving logging operation. This study was carried out in parcels 228, 231 and 232 in Chafroud Shanderman watershed- Guilan. After selecting the sample trees, the condition and quality of residual trees after felling and skidding were investigated. The technical data to be converted and then were the economic value (Rials) using opportunity missed and replacement cost methods. The market value of different wooden products was used to measure the value per cubic meter of extracted wood in the Caspian forests of Iran. After that, felling and skidding average cost per cubic meter was subtracted from wood value. The results indicated that selective cutting can damage the residual trees to value of 947385000 Rials (6072981Rials/ha) due to the forest logging operations. Therefore, the current logging operations also need to be accompanied with careful monitoring by operation personnel and investigated the site status after the logging operations.
