| Course abstract | |
| The study course provides knowledge on logging, timber landing and primary transport operations. The general terms, factors affecting, indices for the characterization of logging are to be acquired at first. Technology and the means for mechanization, the technological planning of tree felling area, methods facilitating to meet the labour safety and ecological requirements are considered as well. | |
| Learning outcomes and their assessment | |
| Students will get:
• Knowledge about forest operations and timber landings technology. • Skills will be obtained to compare particular variants of realization of technology from different aspects. • Attained competence will be sufficient for the assessment of alternative variants. |
|
