Abstract

Harvesting in any way will damage the residual stand and regeneration; however reasonable efforts to mitigate the intensity of these damages will lead to a sustainable forest. This study examines the damages in District 2 Series 2 of Neka – Zalemrood. In order to estimate harvesting injuries, two separate forms were prepared for stand injuries and regeneration damages and sampling were done in two phases, after cutting and after extracting wood. First, the data follow was investigated in normal distribution and data analysis was performed using SPSS software and paired t-test. Results showed that with 95% probability damages on stand after cutting were 8.2% and after extracting wood were 5%. In regeneration section after cutting 2.9% of stand were damaged and 3.2% were destroyed and after extracting timbers 1% Were damaged and 10.2 % were destroyed.
