AbstractGlobally, about 20 million ha of land area is occupied by plantations Eucalyptus . Motor-manual tree harvest-ing techniques (using chainsaws) are still applied in eucalypt plantations, especially difficult terrains or for large- sized trees where mechanised felling may not be an effective and safe possible option to apply. There little information available on motor-manual stands. This ...

BACKGROUND The high spatio-temporal variability of aboveground biomass (AGB) in tropical forests is a large source of uncertainty in forest carbon stock estimation. Due to their spatial distribution and sampling intensity, pre-felling inventories are a potential source of ground level data that could help reduce this uncertainty at larger spatial scales. Further, exploring the factors known to ...

With cut-to-length harvesters, tree stems are measured and cut into different timber assortments at the time of felling. These measurement data collected from harvested trees can be used for decision-support levels forest industry chain also planning when combined with remote sensing data. The aim this study was to examine operational application predicting merchantable stem volume, basal area,...

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...

Black locust (Robinia pseudoacacia L.) is characterized by fast growth, low environmental requirements and aesthetic values therefore it has become a very popular tree planted in forest urban areas. In recent years, altered shape trees with virus-like symptoms on their leaves have been observed. Therefore, the aim of this work was to identify virus species potentially causing visible symptoms. ...

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...

The terms ∆soil and ∆snow can be ignored when evaluating big catchments on a yearly basis under a Mediterranean climate with dry summers. It is assumed that the soil and snow water storage are almost completely exhausted by the end of the hydrological year. The term ∆aquifers can also be neglected when the global water balance is not greatly affected by subterranean circulation. Equation 1 then...
