Charakteristika přirozené obnovy v porostech ŠLP Masarykův les Křtiny na základě dat statistické provozní inventarizace

This diploma thesis deals with the natural regeneration of tree species in forest in conversion to the selection forest. Data collection was carried out using the statistical operational inventory method on the property of the Training Forest Enterprise Masaryk Forest Křtiny. Data was collected in year 2013, and 80 plots were then selected for further processing. The number of individuals of natural regeneration was detected, the species of a tree, their height and damage were determined too. The aim of the thesis was to evaluate the state of natural regeneration and to recommend optimal values of the stand dendrometric characteristics with a view to maximizing the number of individuals of natural regeneration. The results show the dependence of some tree species on the forest stand type and height classes. The models for maximizing the number of individuals of natural regeneration are suitable, for example, in natural regeneration in the forest type complex 3S (fresh oak beech). The optimal values for maximizing the number of individuals of natural regeneration of beech are the number of trees per hectare up to 1 500 ind./hectare, stand basal area/hectare from 16 to 33 m2 and the stand volume/ha from 170 to 430 m3/hectare
