According to the literature, forwarding productivity depends chiefly on log concentration, number of assortments, mean volume, load-size, slope, and extraction distance. However, there is not much scientific knowledge available in continuous cover forestry (CCF) boreal forests, nor whether presence remaining trees actually affects productivity. Thus, objective our study was isolate effect ...

BACKGROUND The development of affordable woody biomass feedstocks represents a significant opportunity in the development of cellulosic biofuels. Primary woodchips produced by forest mills are considered an ideal feedstock, but the prices they command on the market are currently too expensive for biorefineries. In comparison, forestry residues represent a potential low-cost input but are consid...

The impact of agriculture, forestry and metal mining on the quality of fine-grained sediment (<63 μm) was investigated in the Quesnel River Basin (QRB) (~11,500 km(2)) in British Columbia, Canada. Samples of fine-grained sediment were collected monthly during the snow-free season in 2008 using time-integrated samplers at replicate sites representative of agriculture, forestry and mining activit...

We examined the risk factors for heatstroke among forestry workers in Japan during the summer. We distributed a questionnaire to 124 forestry workers to determine heatstroke symptoms, degree of sweating and hydration, as well as perceived hotness and amount of sunlight at work sites. Forty of the workers (32.3%) reported experiencing heatstroke symptoms. Thirteen and 21 of them reported such sy...

Appropriate utilization of forest resources is important for improving rural household livelihoods and conservation in the forest rich areas of developing countries. Using a survey of 1074 rural households in 20 administrative villages in the four southern mountainous townships in Zhouzhi County, Xian, China, we find that there are four forestry-related livelihood activities in our survey site....

Forest resource is the material basis of forestry production and forestry sustainable development. Nowadays the concept of “Digital Forestry” is put forward and 3S technology is used in forestry. Therefore the embedded system of forest resource information acquisition has been designed which integrated embedded technology with GIS, 3G wireless communication technology and GPS. After analyzing t...

assessment and management of the environmental impacts of forest harvesting operations have become increasingly critical factors in practicing commercial forestry. this study investigated soil disturbance from a forest logging system operation on an 8-hectare mixed broadleaved stand in compartment no. 309 in gorazbon district in kheyrud educational and research forest. the objective of this stu...

Carbon leakage can be a problem when seeking to reduce carbon emissions through forest policy. International market leakage is mainly caused by supply and demand imbalances in the timber market. This paper selects China, which is implementing forestry policy changes, as the research object. We begin by offering a brief analysis of China’s forestry policy changes, such as the logging quota and S...
