Effect of wild boar on dry grasslands
Horčičková, Eva ; Vojta, Jaroslav (advisor) ; Hejcmanová, Pavla (referee)
The study was focused on disturbances by wild boar (Sus scrofa) and their impact on vegetation of semi-dry grasslands (Festuco-Brometea) dominated by Brachypodium pinnatum. The research was conducted in military area Hradiště in hilly region of the Doupovské hory. Wild boar rooting activities is main source of disturbances regime in this abandoned, previously agricultural area. The vegetation of artificial small scale soil disturbances was compared to undisturbed control plots and vegetation of natural disturbances by wild boar. Experimental plots were established during the summer 2007. Consequently a vegetation survey of these plots was carried out and soil was mechanically disturbed. Succession on disturbances was annually monitored. The surrounding natural disturbances were also mapped three times a year as a potential source of diaspores and to assess their frequency and effect on the landscape level. The list of species in the 2m, 4m and 16m distance from the experimental plot was also made. Results: Disturbances by wild boar increased species diversity and spatial heterogeneity of semi-dry grasslands. There were some species found on experimental plot, which were present not in the surrounding matrix. Most of them belong to hemicryptophytes and species with long-term persistent diaspores. Presence of...

Monitoring of dear contamination by organohalogen compounds based xenobiotics
Doušová, Petra ; Stoupalová, Michaela (referee) ; Vávrová, Milada (advisor)
Various animal or vegetable origin bio-indicators are used for the assessment of the environmental contamination. The wild animals were chosen for monitoring of xenobiotic based organohalogen compounds. The district health facility staff collected the samples of wild boars in the territory of Central Bohemia. The controlled substances were isolated from the matrix by an extraction. The extraction was made by a petrolether and then it was purified by a column chromatography. A final cleansing of the extract was made by an acid hydrolysis. The determination of the selected analytes was finished by the method of gas chromatography with an electron capture detector. The results gave us basic information about the wild boar contamination of organohalogen pollutants.

Assessment of damage by animals on the family farm in Lhotice
ZEVL, Jiří
The aim of this work was to assess the damage caused by wild boar in terms of ecosystem-based pespective, take into account the influence of historical development, document the current status and predict the direction of development. I focused on the farm of Jiri Zevl in Lhotice. I analysed and evaluated the damages caused by wild boar. I already applied measures in terms of their actual effectiveness. In the years 2010, 2011 and 2012, I focused on all the fields on the farm, where damages were noticed. Farm in the period began to apply these two measures against damages caused by animals: chemical protection by Hukinol and also cultivation awned wheat varieties. I compared damage on fields before and after protection. I've always found out and filed damage just a few days before harvesting. For the actual detection and damage assessment, I chose the method of visual inspection. I measured and calculated surface damage I measured individual damaged areas with a tape measure and method of irregular shapes transformed into geometric shapes, Than I calculated their area. According to my research is chemical protection effective as well as the growing awned wheat varieties. In 2010, there were used no precautions, was the damage 31,539 CZK and there was damaged 18.3% of the area of all fields in research. In 2011, the financial loss decreased to 14 941 CZK and the area damaged by animals to 3.7 % of the total area. In 2012, the damaged area was 7.8 % and financial loss increased to 29 054 CZK. In conclusion I make recommendations for further action that should dechne damages in the coming years. On the issue of damage caused by wild boar on crops, I have two suggestions: 68 First: It is neccesary to handle this issue since its inception. Increase in the numbers of wild boars has caused intensive farming that disrupted the flow of energy in the country. The solution could be partial cancellation of obligations of users of hunting grounds cover damage caused by animals. It is necessary to rethink the system, which works now. Not only hunters should be responsible for damage, but also farmers, or owners. Second: It is necessary to solve the problem of farmers and users of hunting grounds together. It is necessary to choose such a user hunting who will cooperate and will take care to avoid damage. Recovery of damages from the users of hunting area doesn´t solve the problem in the long term sight, it is only a short-term basis and short-sighted.

The Analysis and Evaluation of The Damages Caused by Wild Boar in The Region of Milevsko
KOTALÍK, Tomáš
The diploma thesis is focused on the analysis of the damages which were caused by wild boar on farming plants in the region of Milevsko. Three areas of interest were chosen for the observation (the area around Sepekov, Přeštenice and Opařany). Each of the areas of interest observed was chosen because of its conditions suitable for the occurrence of wild boar during whole year. Each area had also ideal conditions for evaluating of the damages caused by this species on farming plants. The main aim of this diploma thesis was appraisal of the damages caused by wild boar according to the most suitable Czech and foreign methodologies. The observation was realized in the period from the beginning of February 2011 to the end of October 2011. The size of the damages on particular farming lands was measured according to three Czech methodologies (according to Dvořák et al., 2006). Total evaluation of the damages caused by wild boar on farming plants was realized according to Czech methodology by Kamler and two foreign methodologies (by Jonathan Yoder and Ray T. Sterner). The biggest damages caused by wild boar were found out in the area around Sepekov. The most attractive and also the most damaged farming plant was maize in the region of Milevsko. The damages of permanent grass cover caused by rooting of wild boar were found out only in spring term. Winter grains were mostly damaged by wild boar in the period of milky ripeness. In case of the usage of the methodologies for finding out the amount of damaged area it was necessary to choose the methodology according to the kind of a farming plant, the height of a plant and the kind of the damage. All three types of the methodologies used for finding out the total amount of damages caused by wild boar on farming plants were very exact and applicable to the chosen region.

Analysis of the current institutional adjusment of liability for economic damages caused by wild boar in the Czech Republic since 2000
Hekrle, Marek ; Louda, Jiří (advisor) ; Řežábek, Pavel (referee)
Growing populations of wild pigs are causing economic damage, societal risk and the risk of spreading infectious diseases. Czech Wildlife Management defines a wild boar as a renewable natural resource not owned by specific subject and sets hunter's liability for economic damage caused by it. For the purpose of the work was prepared questionnaires addressed to the farming agricultural subjects and representatives of hunter's association in the Czech republic. The author confirmed his hypothesis that the current institutional game management of wild boars leads only to a limited negotiation between hunters and farmers due to bad enforcement of economic damages. Thesis proves, that in most cases economic damagesare not enforced by farming subject. Hunters are in the position of free riders participating in the unwillingness and lack of incentives for farmers to enforce economic damages or to enforce non-equivalent to the amount of damages. It shows that the current institutional adjustment does not support the principle of personal liability and motivation, and does not optimize populations of wild boar and thereby reduce the economic damage.

Assessment of wildlife damage on the family farm Sedláčkův dvůr
BAXOVÁ, Anna
The thesis is focused on game damages on agricultural products and lawns, and their assessment. The theoretical part deals with history of hunting, sorts of damages on agricultural and forest growth, and the most significant furred game of prey. Further are described causes of loss, protection against them, their limitation but also dilapidation. The practical part features lands belonging to a family farm called ?Sedláčkův dvůr?, where were determine a loss caused by game, which were express in percentage. The incurred losses are analyzed at the conclusion. The most significant damages were caused on the lawn green . Lower damages were on the agricultural product.

Evaluation of agrotechnical related measures and methods in relation to wild pig damage.
OPAT, Roman
These days, wild pig, or wild boar, causes considerable damage in the Czech Republic, but also in other countries of almost the whole of Europe. The thesis describes the issues of damage done by the wild pig and the protective measures against this damage. The basis of the thesis was to measure the areas of damaged vegetation of unbearded and bearded varieties of wheat. Damaged areas on individual fields of both varieties were then compared with each other and evaluated. The choice of a variety, as an agro-technological measure against damage done by wild pigs, showed to be very effective. The damages that the wild pig did in unbearded varieties were not done in bearded ones.
