Dynamika přirozené obnovy dřevin v NPR Boubínský prales
 Komárková, Eva
The aim of this diploma thesis was to evaluate the structure and developmental dynamics of natural tree regeneration in the core area of the Boubín virgin forest NNR and also to evaluate the effect of selected factors such as light conditions, water-affection of the site and substrat type on its occurence. By using a system of circular inventory plots all individuals of d1.3 < 10 cm were in 2010, 2012 and 2013 registered and classified into corresponding height class or diameter class. To find out the light conditions of this plots the hemispherical photographies were taken. The main tree species are represented by so-called hercynian mixture (spruce-fir-beech), which is contemporary for the main part in the stage of optimum and the initial stage of disintegration. It emerged that beech (Fagus sylvatica L.) is markedly dominated species in the regeneration layer and is related to water-unaffected sites. On the contrary representation of fir (Abies alba Mill.) is very low and its occurence was not to be found to be conditioned by any of considered factors; neverthless its growing-up has been prooved. Spruce (Picea abies (L.) Karsten) is very poorly able to compete in growing-up with beech, but this fact is not affected by any of analysed factors.
