Evaluating and comparison of two skidding methods using wheeled cable skidder (Case study: Kheyrud forest, Noshahr) [PDF]

مجله جنگل ایران, 2011
Evaluating the cost of different harvesting alternatives is necessary to develop an efficient forest operation plan. This requires estimation of harvesting production rates, equipment and labor costs.

Forest road planning considering road and skidding costs (Case study: Kheyrud Forest) [PDF]

مجله جنگل ایران, 2011
Hyrcanian forests are the only forests designated for commercial timber production inIran. Ground-based skidding is the most common timber harvesting system used in these forests, but due to low road density (1-2m/ha), large parts of the forests are ...
