Learning outcomes and their assessment

The aim of the study practice is to provide students with practical knowledge about the taxation of individual trees, their parts, felling areas and forest stands. During the internship the student learns the methods used in forest taxation. The student acquires the necessary skills in data collection and processing, so that the obtained data can be used for a full-fledged forest inventory.
-During the internship the student learns the methods used in forest inventory, the choice / arguments of the validity of the chosen method is evaluated.
- Being able to handle specialized instruments and software, the obtained measurement results with the specific measuring instrument are evaluated.
- Being able to measuring the parts of an individual tree / trunk, the obtained measurement results for the specific part of the tree / trunk are evaluated.
-Ability to determine taxation parameters at the tree and stand level. The obtained tree and stand parameters are evaluated.
-Student is able to fill in forest inventory documentation, the completed documentation is evaluated.
- Carry out a forest inventory - the inventoried forest area is assessed on a random basis.
