Monitoring zdravotního stavu jedle bělokoré (Abies alba Mill.) na vybraných plochách LS Náměšť nad Oslavou
Nováček, Martin
The diploma thesis pursues an assessment of the health condition of white fir (Abies alba) in selected areas of the Náměšť nad Oslavou forest administration. All 888 of the white fir trees (Abies alba) on the two research grounds, in the 7th age class, were incorporated into health classification, the symptoms of damage to the tree species were evaluated and the presence of wood fungi, insect pests and other negative factors affecting the studied trees was determined. From the symptoms found, it was assessed that among the abiotic damage, drought and wind had the greatest effect on the health of the trees. Among the biotic damages, white mistletoe (Viscum album), wood-decaying fungi and insect pests had a significant negative effect.

Biodiverzita dřevních hub v oblasti Národní přírodní rezervace Divoká Oslava
Nováček, Martin
The bachelor thesis deals with the surveying of the biodiversity of wood fungi in National Nature Reserve Divoká Oslava. The reserve originated in 1.12.2019, therefore it is relatively young and characteristic with its original and close-to-nature landscape. Inside of the reserve were chosen two locations with the highest potential of the presence of wood fungi and there was since the November 2018 to the November 2020 carried periodical survey through errand method. The collection and identification of the sporocarps took place, taking of the photographic documentation, and the evaluated parameters on the ecology of the species and the substrate on which the fungus grew, were entered into the field diary. In total there were 53 species of the wood fungi found, from which two species are entered in the Red List of Fungi (macromycetes) of the Czech Republic.

Biodiverzita dřevních hub v Arboretu Křtiny (Školní lesní podnik Masarykův les Křtiny)
Kotyz, Lukáš
The bachelor thesis focuses on the biodiversity of wood fungi in Arboretum Křtiny. Monitoring of the area started in February 2021, last visit was in January 2022. During this time 15 field trips were done in total. Overall 118 wood fungi were found in the arboretum. Of these, 10 species are in the Red list of fungi of the Czech Republic. Most of the species were found in October of 2021 (97), the least in May and June of 2021 (39). From the total number of macromycetes found, 88 % were basidiomycetes and 12 % ascomycetes. Most of the fungi species grew on Fagus sylvatica (77) and a total of 32 species were found on Salix ssp. White wood decay was noted in more than 90 % fungi species. 93 species were saprotrophic, 21 saproparasitic and 4 parasitic. More than 60 % of fungal species were present in the middle phase of wood decomposition. Over 1/3 of mushrooms preferred the 3rd degree of wood thickness (11–30 cm) and the 3rd degree of bark preservation. The rarest fungi found is Vararia investiens. The most commonly found species were: Fomes fomentarius s. l., Phellinus igniarius, Trametes suaveolens, Hypoxylon fragiforme, Kretzschmaria deusta, Xylodon flaviporus, Bjerkandera adusta, Ceriporiopsis gilvescens, Jackrogersella cohaerens, Eutypa spinosa and Biscogniauxia nummularia.
