Course abstract

Aim of the study course is to provide students with knowledge about the taxation of individual trees, their parts and forest stands. The study course consists of a practical and a theoretical part. The theoretical part deals with the methods used in forest taxation in determining taxation features and tools for measuring taxation parameters. In the practical part, the student acquires the necessary skills in data collection and processing, so that the obtained data can be used in forest management planning.

3. Gains knowledge and understanding of individual tree, forest stand growth, be able to calculate and determine them, - 2. test, practical work
4. Acquires knowledge about the organization of forest territories, practical taxation methods, be able to apply them both in calculations and in nature - practical work
5. Acquires knowledge about forest cartographic materials, use of GIS systems in forest taxation (to be able to apply them), to acquire knowledge necessary for preparation of felling stock, - 3rd test, practical work
