ABSTRACT LEŠKO, M: Analysis of the Structure and Natural Regenerationin a Stand in Conversion to the Structurally Differentiated Forest in Municipal Forests of VeľkýFolkmar [Diploma Thesis] Technical University in Zvolen. Faculty of Forestry. Department of Silviculture, Diploma thesis, Supervisor: doc. Ing. Stanislav Kucbel, PhD., Degree of professional qualification: Engineer "Ing". Elected LF TU, 2018.s. 58. The aim of this diploma thesis will be to analyse the current diameter structure by means of full calipering after realization of silvicultural intervention based on individual selection of trees. On the network of research plots, individuals of natural regeneration (up to 130 cm) will be recorded and the influence of silvicultural measures on the dynamics of regeneration processes will be evaluated. Analysis of the structure change - according to the tree records (according to tree species and diameter class), full calipering of the stand (current status) and after connection with the data regarding tree harvest, the status before the intervention (evaluation of the change of the diameter structure, representation of the tree species) is obtained. The research object will be a mixed stand in the conversionto a structurally differentiated forest in the Municipal Forest of VeľkýFolkmar. The analysis include also the calculation of structural indexes –homogeneity coefficient and index of relative importance.
