The Lodgepole pines susceptibility to Heterobasidion spp. was investigated in three parts ofthis study. In the first part, discs from freshly cut stumps were collected and analyzed to seeif the fungi can spread and grow naturally in Lodgepole pine stands. In the second part …
In this work, I describe the factors that affect the bucking of pine logs on the basis of the machine operator. The aim is to find an explanation why the bucking differs so greatly between requested length results and the actual length results in pine bucking. The used methods …
