| Course abstract | |
| Course includes analysis of techniques and technologies of area and soil preparation, ways of forest regeneration, criteria of their application. Influence of tree species mixture, initial spacing and genetic and physiological quality of plant material on success of regeneration and stand characteristics is assessed. Basic principles and results of tree breeding are discussed. Most important methods of protection against biotic an abiotic damages and thinning of young stands, options to ensure high carbon sequestration and stimulate adaptation capacity, stability of stands are covered. | |
| Learning outcomes and their assessment | |
| During the course students gain knowledge about most important aspects of forest regeneration and afforestation and applicable techniques and technologies as well as basics of forest tree breeding. After the course students are competent to choose the most appropriated regeneration method, species composition, type of plant material, initial spacing and thinning regime in the practical situation. They are skilled to evaluate quality of stand protection and plant material. Students are competent to characterize the significance of using selected plant material and substantiate connection between forest regeneration and carbon sequestration in ecosystem and adaptation capacity of stand. | |
