The operational productivity and costs of tree felling operations can be influenced by several factors, among which, the machine characteristics, slope class, cutting area individual volume trees stand out. Thus, main objective present study was to analyze production cost for two feller-bunchers with different technical characteristics operating in a eucalyptus forest. calculated from time fact...

Abstract Land degradation causes the fragmentation of forest areas. The can be in form a decrease species diversity and carbon storage an area including logged-over This study aims to obtain stand abundance, basal area, potential above ground biomass that used estimating natural recovery Stand measurements were carried out 3 different areas with distance plot from road as differentiating factor...

This pandemic also affected the amount of costs incurred from teak harvesting process. Based on previous research, we tried to compare arising during pandemic. On other hand, Cost analysis community aims analyse by at each process, starting felling, skidding, transportation stages, both in self-managed systems and wholesale systems. Data were collected through observation interviews which then ...

We used a physically based ecohydrological model to predict the water balance and growth responses of a mountain ash (Eucalyptus regnans F. Muell.) forest catchment to clear-felling and regeneration. The model, Topog-IRM, was applied to a 0.53 km(2) catchment for a 3-year pretreatment period, and a 20-year period following clear-felling and reseeding of 78% of the catchment area. Simulations we...

Nacrtak Mechanized felling was introduced in Slovenia at the beginning of this decade, and before that Slovenian forestry relied on motor manual felling and tractor skidding or cable crane yarding. In this research we are dealing with wood forwarding. Model skidding maps were built, using terrain classification and decision support systems for forwarders and tractor trailers. The purpose of thi...

chainsaw is an important machine for tree felling limbing and bucking in hyrcanian forest and the major problems related to using forest machines was sound intensity. the aim of this study was to measure the sound level in occupational exposure of workers, determine the exposure time of workers and comparison of the variables among the workers. this study was carried out in namkhaneh district i...
