Abstract

Assessment and comparison of conventional LOGGING METHODs in Hyrcanian Forest such as large and small Cut-to-length considering their impact on forest ecosystem and COSTs of PRODUCTION in different operating stage can inform us to the advantages and disadvantages of these methods, for suggesting an optimal LOGGING METHOD with low COSTs. This study was carried out in 213 and 227 compartment of Namkhaneh district, in Kheyrud Forest. In this study, the elemental times and effective factors on turn time were identified with 31 and 34 turns were studied with large and small cut-to-length method, respectively. Regression models were developed for these methods using SPSS 11.0 statistical program. The hourly PRODUCTION with or without delays in skidding with Caterpillar skidder in large CTL were 11.65 and 16.68 Cubic meters per hour, respectively. However, for small CTL method, they were 8.78 and 12.95 Cubic meters per hour, respectively. In order to determine the skidding COST, we used proposed model by Forest and Range Organization. The results indicated that on both LOGGING METHODs, the increasing of skidding distance led to increase time and skidding COST linearly.
