Health condition of of trees in natural monument Buky on Bouřňák
Wiedenová, Barbora ; Čížková, Dana (advisor) ; Vachová, Jana (referee)
In the thesis I focused on observing the occurrence of wood-decaying fungi on tree species in natural monument Buky na Bouřňáku. Two areas of 100 x 100 m were mapped, each contained hundred trees of various kind, mostly beech (Fagus sylvatica).
The introduction summarizes information about the location and describes occurring pathogenic fungi and their expanding, biotic and abiotic damage and state of beech crowns. Observation was conducted from April to November, starting with the precise inventory of trees and their marking. Each subsequent month, I observed changes on specific tree species, recorded them and photgraphed detected fungal specimens. Individual species of wood-decaying fungi are described in my thesis.
In the field, apart from fungi, I also observed the consequence of biotic factors that were evident on trunks, branches or assimilation organs. For individual species of beech, I recorded the condition of trees based on defoliation of the crown.
The most frequently occurring wood-decaying fungi in the whole natural monument was Stereum rugosum. This fungi continues to spread and causes decline of several beech trees.
Nevertheless I think the beech forest should be left to its spontaneous development, because it is a small protected area, more correctly natural monument.
