Forest Valuation – Comparison of Valuation Methods in the Czech Republic – Ascertained Value and Market Value
Loskotová, Dominika ; Šafránek, Zbyněk (referee) ; Alexandr, Pavel (advisor)
The aim of this study was to determine the most appropriate valuation method used for market valuation of forest property in the Czech Republic and to determine suitability for defined types of forest properties. Secondly, the aim was to compare market values with prices assessed determined by administrative methods according to Valuation Decree. Additionally, definitions and historical evolution relating to valuation of forest property and specificities of forest properties have been presented. In the theoretical part the study is analysing and comparing the evaluation methods. There are six forest properties from The Czech Republic evaluated in the practical part of the study. Four methods of evaluation have been demonstrated. The study compares used methods and evaluates suitability of each method for presented forest properties.

Development of Forest Valuation Methods in the Czech Republic
Absolonová, Jana ; Klika, Pavel (referee) ; Vala, Vlastimil (advisor)
The aim of this thesis was to define the issue of determining the administrative price and market value of forest in the Czech Republic. The thesis describes the evolution of methods of determining the price of forest in history since 1897. Furthermore, the thesis deals with the current problem of determining the market value of forest in the Czech Republic. The current situation is documented by a case study, which deals with the determination of the administrative price and market value. The study compares these two values. The final analysis is focused on recommendations of corrections of existing valuation regulations and method of market valuation of forest.

Valuation of a Forest
Rumanová, Jana ; Scheuer, Pavel (referee) ; Alexandr, Pavel (advisor)
The aim of the thesis was to explore current approaches used for valuation according to the valuation regulation. The next aim was to choose appropriate method for finding usual price and compare it with the price assessed determined by administrative methods according to Valuation Decree. Comperative method was the chosen method. There are six forest properties from The Czech Republic evaluated in the practical part of the study. The conclusion of the thesis summarizes detected information from the area of valuation of forest.

Heterogeneity in forest vegetation monitoring with remote sensing
Kolešová, Petra ; Kolář, Jan (advisor) ; Potůčková, Markéta (referee)
Heterogeneity in forest vegetation monitoring with remote sensing Abtract The main aim of this diploma thesis is to examine the suitability of various classification approaches for forest vegetation categorization using Landsat 8 satellite imagery. Two satellite images acquired during vegetative period (8th March, 27th July 2013) were chosen. The overall goal of the study is to explore the potential of using statistical methods to obtain information about forest heterogeneity in a given territory. Chosen study sites are defined by administrative boundaries of selected municipalities from South and Central Bohemia located within following municipalities with extended powers - Blatná, Milevsko, Písek, Příbram and Sedlčany. Supervised and unsupervised classifications were used based on obtained training areas and orthophoto. The definition of chosen classes (coniferous forests, mixed forests, ecotones, structurally homogeneous deciduous forests and structurally heterogeneous deciduous forests) was identical with the categories used in "Project MT 11425-5/2010 The Mapping of Natural Zoonoses Focal Points, Transferable on Humans in the Czech Republic and Their Changes Affected by the Modification of Climate". Due to large amount of training datasets obtained from field survey, ortophoto and spectral analysis,...

Morfologická analýza vybraných bukových porostů genové základny revíru Raškov (LČR, s. p., Lesní správa Ruda nad Moravou)
Křížek, Petr
Beech is an important tree species in Czech forests, its share is currently around 8.4%, although it has historically been much higher in the Czech Republic. The aim of this work is to create a list of selected beech stands with evaluation of their morphological quality. A three-stage Schädelin classification was used for quality evaluation, which assesses the height, the quality of the trunk and the quality of the tree crown. The quality assessment was carried out in 18 stands, which are part of two units - the southern and the northern side of the gene base. Stands are divided into three groups according to their age (young, middle-aged and mature stands). Basic dendrometric measurements were also performed within the above mentioned stands. Finally, a list of forest management recommendations and reproduction method for each of the evaluated stands was created.

Projekt zalesnění kalamitních holin na území LS LČR Vítkov
Valíček, Jakub
The aim of this diploma thesis is to elaborate a complex project of restoration of clearing due to salvage felling in the forest district Odry and reconstruction of the spruce in the district of Heřmánky. The forest districts are under the administration of the state enterprise Forests of the Czech Republic, specifically under the Forest Administration of Vítkov. The project includes an analysis of causes of declining and dying stands in the selected area, stand condition, condition of clearings and young plantations, site preparation, methods of woody species and methods of recovery, protective and defensive methods of established plantation, direct economic costs.

Forest species determination from satellite data
Launer, Michal ; Kolář, Jan (advisor) ; Brodský, Lukáš (referee)
Forest species determination from satellite data Abstract This thesis examines the species composition of forests from satellite images using the pixel classification. The research was done on 24 forest locations in The Ustecký Region, The Karlovarský Region, The Plzeňský Region and The Central Bohemian Region in the Czech Republic. In this thesis, data from the Landsat-8 and Sentinel-2 satellites from summer season and the Random Forest Classifier method were used. The layer of species composition of forests from map portal LhpoMap was used as reference data. The method of work consisted of a broad literature search to select the most favourable classifier and to choose the most advantageous input parameter values to achieve the highest overall accuracy of the classification. The practical part was focused on creating a software classification process. The accuracy of the individual image values was verified using matrix errors. Based on the literature search, the Random Forest classifier was used to classify the images. Parameter values were used for the Gini criterion, 500 decision trees, and the other parameters were left with default values. The entire classification process was performed in ArcMap and ArcGIS Pro software using Python programming language with the help of the sklearn.ensemble module...

Forest species determination from satellite data
Launer, Michal ; Kolář, Jan (advisor) ; Kupková, Lucie (referee) ; Brodský, Lukáš (referee)
Forest species determination from satellite data Abstract Examining the species composition of forests from satellite imagery is constantly evolving. The new ways of exploring forests from the satellites make it easier for foresters to maintain a more accurate and up-to-date overview of the state of forests. In this work, the research was made on the forests in the cadastral territories of Osvětimany and Buchlovice in the Chřiby Mountains in the Czech Republic. In this work, data from the Landsat-8 satellite from three seasons and the Maximum Likelihood Classification method were used. The reference maps were used as reference data. The method of work consists in the fact that 6 frames were classified with the help of training sets using Maximum Likehood Classification. Subsequently, the pixels which were at least 4 times out of 6 ranked in the same class after the classification were selected. Based on these pixels, artificial training sets were calculated for each of the 6 frames, and they were used for another classification with the expectation of better results. The accuracy of the individual classification frames was verified by an error matrix on the crop maps. Keywords: remote sensing, forest canopy, forest tree types, forestry map
