SÉLEŠ, Erik: Health status and resistence potential of selected vegetation at LS Budča. [Diploma thesis] / Erik Séleš .- Technical University in Zvolen. Faculty of Forestry; Department of Integrated Forest and Landscape Protection. – Tutor: Doc. Ing. Milan Kodrík , CSc. Zvolen: LF TU 2017 The work briefly analyses the health status of the vegetation at LS Budča based on the results of random cutting in the last 5 years for spruce trees. It evaluates the results of practical assessment of vegetation damages caused by biotic and abiotic deteriorative agents and their impact. Based on the information acquired it interprets the endurance potential and suggests measures to improve the health status and the endurance of the vegetation at individual lots. The result of the diploma work is the conclusion that the health status of spruce vegetation in the researched area is in a negative state and in the near future it will be necessary to make specific measures that will lead to the improvement of this state as well as to the improvement of the endurance potential of vegetation with spruce trees.
