Course abstract

The course includes land and soil preparation technology and technical analysis, regeneration type, the application of criteria analysis in the context of the stated objectives of reforestation. Throw analyzed tree species, planting/sowing thickness and reproductive material genetic and physiological effects on the quality of restoration success. Highlight the main methods of planting/sowing in protection against biotic and abiotic factors and thinning, to provide for a high level of carbon sequestration and contribute to foster adaptability, persistence.

Learning outcomes and their assessment

The study course includes students knowledge on major reforestation and afforestation aspects of applied techniques and technologies. Finishing the course students are competent to choose the most appropriate for different situations reforestation types, species composition, type of planting material, thickness, agro-technical care treatment, appreciate planting stock and planting/sowing protection measure execution quality. Students are able to describe the reforestation relationship with carbon sequestration in forest ecosystems and forest stands adaptation potential.
