Course abstract

Master students acquire knowledge on tree planting and plantation forest planting technologies and legislation, tree species and plant material selection, planting techniques, care and harvesting. The productivity and economic benefits of tree plantings and plantation forests.

Learning outcomes and their assessment

Knowledge - Master students have mastered the latest trends and become familiar with tree plantations and plantation forests. They are able to choose the species of woody plants that are suitable for the given place and conditions, because they have acquired knowledge about the growing conditions and agricultural machinery necessary for them, 1. test and 2 study tours.
• Skill - familiar with the latest technologies for planting, managing and harvesting forest plantations and plantations forests, is able to choose the most appropriate. Is able to plan and calculate the required resources, estimated costs and benefits, including an ecological footprint, 2. test and 1. seminar.
• Competence - understands and is able to justify the establishment of tree plantations and plantation forests from the point of view of sustainable management, 3. test and 2. seminar.

Practical works should be carried out in groups involving the development of a plan for the installation of plantations and plantation forests, including care and protection, harvesting and utilisation of products, the necessary resources, expected costs and benefits, etc., prepare a group report and 2 presentations on the installation of tree plants (1) and plantation forests (1) for specific plants species.

Requirements for awarding credit points

The number of lessons missing from the course may not exceed 10% of the total number of lessons scheduled. You must have successfully written three quizzes (Test 1. “Choice of tree-growing species for specific growth conditions and for the installation of tree-growing plants and plantation forests”; Test 2. “Ecological aspects, care, protection and growth of wood plants and plantation forests.” Test 3. Harvesting and use of “harvesting” of plants and plantation forests.) Take part in training tours, practical work and carry out own-initiative work. Reports have been successfully prepared for each working group and presented prepared presentations: “N tree plantation (s)” and “N plantation forest installation”.

Description of the organization and tasks of students’ independent work

Take an independent look at the latest spotlights available. It is necessary to continue independently to extend the scope of the information generated in lectures and practical works, using the basic literature, additional literature and the scientific resources available on the Internet, as indicated in the study program and in the presentations. The groups should work independently to prepare for three quizzes and to write a report and prepare presentations (for each working group, one for “N tree plantation (s)” and the other for “N plantation forest installation”; the duration of each presentation for 15 min +5 min. discussions).

Criteria for Evaluating Learning Outcomes

The assessment of knowledge, skills and competence takes place on a 10-party scale. An oral and written answer shall be successful if at least 50% of the questions have been answered correctly. The final evaluation consists of a cumulative assessment of tests and practical works (reports and presentations) of a study course.
