Sustainable natural forest management initiatives in the lowland tropical forests of Bolivia require that cost-effective measures be identified to help maintain timber stand quality and reduce damage to advance regeneration during logging operations. This study considered the potential costs and benefits of including two ‘best’ management practices the pre harvest flagging of future crop trees ...

There has been a growing awareness of the need for sustainable forest management among engineers during last decades. The selection best harvesting system logging operations plays fundamental role in this effort. Nowadays, decision-making process, rely on their own experience, and it is to be expected that evaluation level appropriateness may biased. potential solution problem implementation AH...

The objectives in this study were to develop and test a data analysis system for calculating machine productivity from GPS-derived positional information alone. A technique was used where positions were ‘filtered’ initially to locate specific events that were independent of what actually traveled the path, then these events were combined using user-specified rules into machine functions. The sy...

The study used time studies and cost analysis to assess potential economic benefits from site preparation reductions resulting producing coarse woody harvesting residue (CWHR) for bioenergy. In contrast, previous have predominantly anecdotal estimates of costs.The was performed in a recently clearfelled 15-year-old plantation Eucalyptus globulus (Labill) Tasmania, Australia. area consisted the ...

hyrcanian (caspian) forest in northern iran with many endemic and endangered species is a rich area for biodiversity. the use of ground-based skidding is well accepted practice for the extraction of timber from the forest, but this has tended to cause the greatest environmental problems. the aim of the study was to evaluate and comparison of environmental impacts, residual stand damage, regener...

Salvage logging is increasing in Central Europe because of the growth severe meteorological events, and timber harvesting these conditions challenging terms both productivity performances safety operations. In recent years, with increase natural calamities, several researchers studied machinery regarding salvage carried out by ground-based systems. fact, a common post-disturbance management app...
