Felling trees, which is the basis of forestry activities, dangerous and difficult work that needs to be performed carefully. These activities can affect forest workers’ safety, damage remaining forest, or reduce value extracted product. Most accidents injuries in operations occur due trees not falling desired direction. Directional mistakes tree felling processes underestimating criteria negati...

The objects of research were forest plantations, passed through renovation rubles in the Arkhangelsk forestry region. Trial plots established spruce plantations (bilberry and sphagnum forest), on fresh haulage, apiary, old haulage after felling more than 30 years ago. Based results research, a model was built, with help which it is consistently assessed during course what happens to stand cutti...

-A chipper-fonuarder system offers an alternative for biomass hawcstfng. Components are a small feller buncher for felling and bunching. and a chipper-forwarder that chips at the pile and transports the chips to roadside. In a case study on a mixed pine and hardwood site in Georgia after conventional hawesting, production rates and cost estimates for a prototype chfpperforwarder were developed....

Prolonged exposure to hand-arm vibration (HAV) generated by chainsaws can cause HAV syndrome, i.e., disorders in the upper extremities of forestry workers. Progress of HAV syndrome depends on the intensity of mechanical vibration transmitted throughout the body, which is directly proportional to coupling forces applied by the woodcutter to a vibrating tool. This study aimed to establish a metho...

Industrial logging has become the most extensive land use in Central Africa, with more than 600,000 square kilometers (30%) of forest currently under concession. With use of a time series of satellite imagery for the period from 1976 to 2003, we measured 51,916 kilometers of new logging roads. The density of roads across the forested region was 0.03 kilometer per square kilometer, but areas of ...
