The impacts of three timber harvesting techniques (manpower,
skidder, and skyline) on residual trees, seedlings, and
timber products were investigated in natural oriental spruce
stands in Artvin, Turkey. Each of timber harvesting
techniques was used in 5 different harvesting sites. The
degree of damage caused by timber harvesting techniques in
the residual trees, seedlings and timber products was
calculated as based on injuring size. The results showed
that timber harvesting techniques resulted in damages to
residual trees, seedlings, and timber products, but the
degree of damages caused by the harvesting techniques was
significantly different. The highest level of damage was
caused by manpower, followed by skidder and skyline
harvesting technique. These results suggest that the damages
caused by logging can be minimized by using proper timber
harvesting techniques.
Key words: Logging, manpower, skidder, skyline,
harvesting damage. |
