Hodnocení koeficientu pro určení průměru kmene z pařezu u vybraných dřevin
Jakša, Stanislav
This study aims to determine the appropriate conversion coefficient for calculating the trunk diameter at breast height from the stump. A total of 1,150 trees of five different species - small-leaved linden, large-leaved linden, silver birch, Scots pine, and black pine - were measured and evaluated. The tree girth was measured at 20, 30, and 130 cm above ground level, and their physiological vitality and health status were assessed. Conversion coefficient was determined for stump heights of 20 and 30 cm, as well as for individual tree species.

Inventarizace a tvorba databáze dřevin v Arboretu Řícmanice
Zrníková, Michaela
The aim of the bachelor thesis was the inventory of selected tree species in Řícmanice Arboretum. The oldest plantings from 1925–1938 and young plantings from 2018–2022 were mainly dealt with. The basic variables (height, trunk circumference at height, crown set, crown diameter, root collar diameter) were determined for the monitored trees using common dendrometric methods. The vigour, health, damage and other parameters were also determined and tree treatments were proposed. The found data were used to update the database (attributes of the map layer) created within the thesis Inventory and database creation in the Arboretum Řícmanice (Suská, 2006) and the map layer created within the thesis Information system of the Arboretum Řícmanice (Marek, 2006). The thesis includes detailed photo documentation of the field work on the attached DVD. The collected data and information were graphically processed into summary tables and graphs, which include the current periodic increments for the period 2005-2022.

Provedení detailního fytopatologického průzkumu a návrhy pro zlepšení stavu dřevin v Zoo Brno
Helánová, Sylva
The bachelor's thesis deals with the evaluation of the condition of woody plants, their vitality, health status, stability, operational safety and perspective. Furthermore, by proposing interventions to optimize their condition according to the methodology of the Nature and Landscape Protection Agency of the Czech Republic. A total of 200 trees were evaluated at the site - 11 small-leaved lindens (Tilia cordata Mill.), 11 hornbeam (Carpinus betulus L.) and 178 white oaks (Quercus petrea Liebl.). A field survey was carried out on these trees from March 2021 to March 2022. The results show that the trees on the site are not in good condition, their vitality and health are reduced. The presence of wood-destroying fungi such as Laetiporus sulphureus (Bull. Murrill) and Agrilus biguttatus (Fabricius, 1776) has also been discovered.

Zhodnocení ujmutí výsadeb v zámeckém parku v Lednici
Zajíčková, Markéta
This bachelor thesis is focused on the quality checks in new established plantings considering the quality of planting material such as the execution of the work. In the theoretical part the reasons of the current unsatisfactory situation are discussed and following conclusions are drawn. Another big issue which this bachelor thesis is dealing with are the effects of those plantings on human psyche, social contacts or on its actual surroundings. In this part theoretical background used to analyze local climactic and pedologic conditions is described and explained. Using this method helped with determination of the suitable taxon and other important factors that tree nurseries need to fulfil. In the practical part the new established plantings are evaluated. Data was noted according to newly created method. Results were marked into map materials using the ArcGIS program which led to several updates on the current maps. In the conclusion results are discussed and commented and following solutions, not only in the modal area but also global ones, are suggested.
