Testování efektivity ochranných nátěrů před ohryzem dřevin bobrem evropským (Castor fiber)
Ševčíková, Eliška
Testing of the effectiveness of protective coating materials for preventing prowsing of woody species by Eurasian beaver (Castor fiber) This bachelor thesis deals with testing of the effectiveness of four protective coating materials for preventing browsing of woody species by the European beaver and evaluating the most effective one. Tested were commercial product Wöbra, a mix of Aversol and a material bitrex, a mix of Aversol, bitrex and silica sand, and abrasive coating material, compounds of which are a business secret. The effectiveness of these coating materials was tested in the floodplain forests, where is a long-term occurrence of the European beaver. The testing took place on standing trees, and partially on pre-felled trunks that were treated with the coating materials beforehand. The most effective of the tested protective coating materials was the commercial product Wöbra. This material was effective in 100 % of the cases of its use. Other materials showed slightly lowered effectiveness, as low as 80 %.

Zhodnocení významu škod zvěří na vinicích v okolí obce Limbach
Hlavatovič, Ondrej
This bachelor thesis deals with the assessment of the importance of wildlife damage in vineyards. The vineyards on which the field investigations were carried out are located in the vicinity of the village of Limbach, located in the Pezinok district. The actual damage assessment was carried out using the walking method on three areas of interest using bite plots located at the beginning, middle and end of the vineyard. Subsequently, the economic impact of the damage on the individual areas of interest was quantified. The work also included monitoring of the intensity of vineyard use by wildlife, which was carried out using photo traps placed at the points of arrival of wildlife in the vineyard.

Analýza využitelnosti jednoduchých indikátorů pastevního tlaku zvěře na les pro plánování lovu v honitbách
Rachůnek, Karel
This work deals with the analysis and evaluation of the usability of simple indicators of grazing pressure of game on the forest. The territory in the Zlín region was selected for the elaboration of this bachelor's thesis, specifically the hunting of MS Kyčera. The field survey was performed by the patrol method. Data from control and comparison areas (CCA), transects and artificial cultures were used to assess damage. Eight stands were selected for evaluation. Three main tree species in the area were evaluated, namely beech (Fagus sylvatica), Norway spruce (Picea abies) and white fir (Abies alba). Based on the damage by grazing pressure, the number of ungulates in the given area was evaluated.

Škody zvěří v honitbách Lesů České republiky,s.p., Lesní správa Šternberk
Ellnerová, Hana
This bachelor's thesis deals with game damage that was caused in hunting areas of the Šternberk forest administration. The aim was to verify whether the increased catch is reflected in the area of damage. Using a statistical investigation, I developed a regression analysis of the data, which showed that there is a relationship between hunting and damage. But this addiction has the opposite character than I expected. I thought that with increased hunting, the damage caused by game would decrease. In the case of my investigation, the amount of damage has an increasing tendency despite the increased catch.

Analýza parametrů sazenic lesních dřevin z hlediska atraktivity pro prase divoké (Sus scrofa L.)
Petrů, Markéta
Increasing population of wild boar correlate with increasing damage not only on agricultural lands on crops or grasslands, but also in forests. This damage is mainly on new forest tree plantations which in no way contributes to the successful restoration of clearings after the bark beetle calamity and has a negative impact on the economy. This diploma thesis describes possible influences that may affect the plants attractiveness for wild boar and their damage. An inventory of plants damage was carried out on randomly selected areas in the areas of southern, central and eastern Moravia. A series of experiments with plantings was also performed on the experimental area in the Moravský Krumlov game reserve, where the behaviour of pigs towards these plantings was monitored by the analysis of damaged seedlings and also from pictures taken by photo traps. Obtained inventory data showed us that the wild boar preferred containerized seedlings and deciduous tree species however the experimental system planting did not show a preference for the root system. Seedlings damage was demonstrated in the vast majority only by pulling or rooting without damaging the root system. In terms of time the seedlings were most damaged in the first week after planting, then the risk of damage decreased. To reduce the risk of disturbance by pigs on plantings a method of protection against this damage is not known yet, so the most effective solution remains to reduce the population of wild boar in affected areas.

Posouzení vlivu mufloní zvěře na odrůstání kultur a nárostů na pozemcích obhospodařovaných Lesním družstvem obcí Ledeč nad Sázavou
Zmeková, Nikol
This thesis negotiates with assessment of moufflon fluence on growing of cultures and natural young growths of the lands in holding of the Forest cooperative Ledec nad Sazavou. The secondary aim was determination of optimal quantity of animals in monitored areas, based on founded facts, and to compile proposal of provision which would lead to damage reduction. As method for finding actual number of moufflon population, there were used direct and indirect countings of animal population. Assessment of moufflon fluence on growing of cultures was based on terrain examination, following by of damage. Evaluation of growths was done on experimental lands. In this thesis, there are also information about damages caused by moufflons on forest growths and their elimination options.

Obnova lesa na kalamitních holinách VLS, s.p., divize Lipník nad Bečvou, LS Hlubočky
Provazníková, Pavla
The aim of the dissertation was to analyze the state of cultures in bare areas incurred by the withering away of spruce growth. The dissertation was undertaken on the properties of VLS ČR, s. p., in the economic forest unit of Hlubočky and Bores. The monitoring took place in 18 research areas which were afforested between the years 2007-2015, where 9 areas were afforested with Norway spruce and 9 with European beech. The height of the over ground part and the thickness of the root crown were measured and the presence of damage caused by wild game was evaluated. The monitoring for the purpose of establishing the state of the young spruce and beech growth took place in 10-15 year old growth areas where the trees per hectare, damage by wild game and the percentage of defoliation were evaluated. The third aim of this work was the framework evaluation of the afforestation costs and the care of the cultures according to data from forest management accounting. The monitoring of research areas afforested between the years 2007-2015 found that beech plants were more damaged by browsing than spruce plants. The monitoring of young spruce and beech growth established more damage of the young spruce plants by deer barking and browsing rather than the young beech plants, which are healthier. It was further discovered that the beech growth from natural renewal, which are thicker, are less damaged by wild animals. The evaluation of data from the forest management accounting established that the costs for one renewed hectare on average amount to CZK 64,000, the treatment of one hectare against forest weeds on average cost CZK 9,700 and the protection of one hectare against wild game expends on average CZK 3,470.

Využití statistické provozní inventarizace jako základ monitoringu vývoje škod zvěří na ŠLP Křtiny, LÚ Borky
Brandejsová, Markéta
The aim of this work is to analyze data on the damage caused by game from the database Field-Map program of operational statistical inventory. This inventory was carried out in 280 inventory plots to forestry section Borky school forest enterprise Masaryk forest Křtiny, in 2003, 2008 and 2013. Another aim is a suggest a method and a method of long-term monitoring of game damage to forests. Information on damage by game were evaluate in the relevant graphs in relation to the type of stand (coniferous, broadleaf and mixture) edaphic categories and game evidence (above game hunting). Next, the data were compared based on the general linear models in statistics. At principal species and accessory species in relation to the growth was the considerable increase by game damage. Data of game damage depending on edaphic categories showed the greatest harm to the ecological variety of nutrients. After the use of SPI in this work (the evaluation) and keep to relenvat principle of this system, this method was recommend as flexible method for long-term monitoring of the development of game damage to LÚ Borky.
