Dolenský, Tomáš
Abstract Name: Tomáš Dolenský Thesis title: Proposal of remedial tree work on lime tree with statutory protection in Jílové u Prahy. The approach of presented theses: Proposal of remedial tree work on lime tree with statutory protection in Jílové u Prahy, can be also applied to large trees which do not have statutory protection. Practical applications of tree hazard remedial actions are shown in this case study. Remedial tree work is studied in theory and executed in practice. The literature review lists different approaches how to care for such trees, from the diagnosis to actual undertaking of tree work itself. The methods of the tree management undertaken on this tree are described in each step: tree survey and assessment, problem diagnosis, plan of actual remedial actions and their practical implementation.

Biodiverzita dřevních hub v urbanizovaném prostředí České republiky
Böhm, Šimon
The thesis deals with wood fungi, especially in the urbanized environment. In the field-work, various types of wood fungi were registered. The aim of this monitoring was to identify or verify their frequency, the most common host species, the effect of the in-fection on vitality, state of health, and tree stability. In addition, this work compares the differences between species of wood fungi occuring in urban environment and those found mainly in forests and nature reserves, whereas the most frequent species are described in detail. Last but not least, there are listed cases of tree failure due to wood fungi in the urban environment. Fomes fomentarius, Phellinus igniarius, Phellinus ro-bustus, Ustulina deusta, Inonotus hispidus were found to be the most common types of fungus in cities. Concerning the biodiversity of fungi, there were discovered significant differences between the city and the forest environment, particularly due to the share of coniferous and deciduous trees. As for the found cases of tree failure, they show that Fomes fomentarius and Ustulina deusta are the most common causes of the infection.

Zhodnocení biologického potenciálu dřevin na lokalitě Třešňový sad Kosíř lomy a specifikace managementových opatření pro udržení tohoto potenciálu
Novák, Karel
The study of tree-bound organisms nowadays constitutes an essential prerequisite for understanding the status of the trees from the perspective of biodiversity. Fruit orchards also have a specific position for biodiversity due to their high biological potential. The work was dealt at the site of cherry orchard from the part belonging to the particularly protected area of the Kosířské lomy. A dendrological survey was carried out, supplemented by a listing of organisms found on the basis of regular field patrol. An inventory of all found organisms of the site was created, supplemented by the results taken from the flight impact trap capture. On the basis of the collected information, a proposal for interventions was created on the examined trees, including design of management measures to maintain the biological potential of the site. The results of the work proved the importance of the tree species in the area of the cherry orchard under examination from the perspective of the presence of bound organisms and thus provide further proof of the importance of the area Kosířské lomy.

Veřejná zeleň a rozptýlená zeleň na katastrálním území obce Nový Šaldorf
Hrbáčková, Barbora
The bachelor’s work deals with the problems of the public and sparse greenery in the village of Nový Šaldorf. The village lies in the district of Znojmo, which is located in the Southern Moravian Region. The introductory part defines the basic concepts, which appear in this work, and the basic data of the village and its climatic conditions. I will deal with the evaluation of the trees and shrubs and their mapping in the village. I will assess their health status, vitality, stability, forest mensuration quantities as thickness and height of the trees. The work also includes the accompanying documentation and photo-documentation. At the same time, QR codes and SWOT analysis are the remarkable items in the work. I would like to attract by QR codes not only the inhabitants of the village, but also the tourists who come to the village for wine and culture so that they are also more interested in the vegetation elements.

Vyhodnocení možnosti detekce dutiny poklepem
Hemza, Jiří
The thesis deals with the possibility of utilization and sensitivity of the trunk examination by tapping in assessing the defects affecting the stability of the trees. A dendrological survey was conducted in the area of interest and then there were trees selected to assess the presence and extent of the cavity by tapping. The tapping using a small mallet was done on selected trees at the certain level. The tapping was subjectively evaluated by listening. The sound of tapping was recorded using the microphone and the recorded sound was further analyzed. At the same levels like tapping there was used the ArborSonic 3D Acoustic Tomograph to determine the extent of the cavities in the trunk of selected trees. The same extent of observation was also performed on a sample of a trunk with and without cavity in laboratory conditions. The values obtained were compared with each other for the purpose of verifying usability by tapping using a small mallet while assessing the trees to determine the presence of the cavity and its extent.

Biodiverzita dřevních hub z rodů Fomes, Ganoderma a Phellinus, v urbanizovaném prostředí České Republiky
Mikesková, Iveta
Wood fungi are a common problem in urban areas. Bachelor thesis is focused on the families Fomes, Ganoderma and Phellinus. In addition, Fomitopsis and Perenniporia are processed. Locales of the urbanized environment were recorded with trees affected by these genes. Measurements of dendrometric parameters and arboristic evaluation were performed. Cases of tree species that have been affected by the above-mentioned genera have been described and on this basis the effect of these mushroom families on the operational safety of the tree species has been evaluated. Subsequently, a database was created based on the results of the work. Altogether, 236 fungi finds were recorded in 33 areas of cities and municipalities in the Czech Republic. It has been found that some species do not occur in the urbanized environment, as opposed to Ganoderma adspersum. The species Fomitopsis pinicola was found on a different spectrum of hosts than literature said.

Posouzení možnosti identifikace hnilob kmene s užitím termokamery
Fiala, Michael
This study is focused to possibilities of using thermography in tree assessment in urban greenery. It was took 628 infrared images of 43 trees. On these trees was determine the extent of damage and decayed wood and cavities. It was also acquired 555 photos in visible spectrum for comparison. For the verification of heat transfer in a tree trunk and bark were made the measurements of temperature development in different depths of trunk with using a thermocouple thermometer. In one case was measured the sap flow. It is not possible recommended infrared cameras as a helpful tool for determining cavities and decayed wood in trees. Interpretation of results obtained from infrared imaginings is difficult and its doesn't show anything more than direct observation in the field. Moreover some of visible defect weren't detected by thermography. Application of infrared cameras can be helpful for evaluation of presence the other organisms dependent on a tree cavity.
