Investigation ground based logging damages on natural regeneration in a selection cutting stand in the Caspian forests of Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2012, Vol 2, Issue 9
Abstract
In this study ground based logging damages on natural regeneration following selection cutting were investigated in Nav Asalem forest in the Caspian forests of Iran. Systematic plot sampling method before and after finishing logging operation was used for collection of data. Results showed 5.8% of natural regenerations were wounded and 9.7% were destroyed by logging operation in the study area. The most percentage of wounded and destroyed regeneration was observed on Acer cappadocicum (10.1% and 13.9%), while the least percentage of wounded and destroyed regeneration were observed on Carpinus betulus (4.1% and 6.4%). Extent and severity of damages to regeneration were occurred in the winching area. The results indicated that percentage of logging damages on regeneration were increased with increasing of height of regeneration.
