Course abstract

The study course provides knowledge about timber landings and relevant operations, different technological variants for energy wood production, low-grade and residual wood utilization technology. During the course students are acquainted with indices of different aspects, useful for assessment of alternative variants.

Learning outcomes and their assessment

Students get
• knowledge about technology in stationary timber landings, energy wood industry, and for low-grade wood useful utilization.
• Skills how to make unbiased evaluation of technological variants are acquired.
• Gained competence is sufficient for decision making to choose appropriate development directions of forest management.
