Okus dřevin při různých způsobech ošetření proti buřeni na LHC Střílky
Navrátil, Jakub
This bachelor work "Damage of trees at different ways of protecting against weeds at LHC Střílky" examines the effectiveness of treatment for weed grazing on artificially regenerated stands. These damage caused by red deer mainly. For comparison, the authors also explored grazing on natural regeneration in designated transects, which allows us to observe the effect on various means of protection against natural way of recovery. Bachelor work also deals with not only biological, but also economics way. From the obtained results, mentions a proposal for the best solution in terms of the economy and also in terms of good growth cultures.

Influence of vertebrates on recovery spruce and rowan growth in natural spruce forest of Krkonoše
SÍČOVÁ, Petra
Animal influence has in wood ecosystem big importace. Previously responded amount of animals to population curves of big beasts of prey. Since the time, when man started to regulate animals, he has to database, how big is each population and which density of animals is optimal according to local conditions. The aim of my work was to find out the influence of vertebrates on recovery and growth of Sorbus aucuparia and Picea abies. The research, I have been doing during growing season of the year 2007, contained field work on four LRA and one transect in Krkonoše. Work involved monitoring movement notes of vertebrates, schematic layouts of tree rings of experimental nurslings of spruce and measuring seeding of rowan. Counting, layouts and measurings were processed into schedules and consequently analysed. It was found, that amount of deer animals is raising and its influence on recovery is therefore more significant. Damage, which was found out on plants of spruce has raised since year 2000. Results has shown, that the slight browsing has increased by 10% compared to year 2000. Big effect on rowan recovery has instead of other also altitude which is connected with climatic conditios. By reason of raising deer animals in the area of Krkonoše national park and necessity its regulation, further monitoring of vertebrate influence on wood ecosystem is recomended.

Analýza managementu populace jelena lesního v oblasti chovu Vlára
Stiksa, Martin
This bachelor thesis deal with the game breeding area Vlára and about breeding red deer in this area.The breading area Vlára is situated in the east of Czech Republic on boarders with Slovak Republic. The aim of the work is to create literature review about right management of red deer (Cervus elaphus) population, than processing informations about breeding areas and last but not least processing materials about red deer breading area Vlára. The main task of the work is to evaluate the population of red deer in breeding area Vlára and propose measures to put right identified shortcomings. For my thesis I used data which ORP Valašské Klobouky and evaluative committee for red deer in district Zlín provides to me. In bachelor thesis there are processed data from years 2009 to 2018 and focus on added red deer population status, modified red deer population status, hunting statistics and results from trophy exhibitions.

Zhodnocení faktorů ovlivňujících intenzitu poškození porostů na území podniku Kolowratovy lesy
Svoboda, Tomáš
The work assesses the factors affecting the intensity of damage to vegetation Europen deer and sika deer on the holding Kolowrat forests. The study is to compare the population density of each game species, found less used method of counting dung piles on the strips transect, where the resulting states do not correspond to states of documents supplied by the owner of the hunting grounds. The observed population density is further compared with the number of trees damaged by bark consumption. The result of this comparison is the finding that the damages do not increase proportionally with the number of animals. The work concludes with a proposal of measures to reduce damage, arising out of tree species in the surveyed area.

Škody ohryzem, loupáním a následnými hnilobami v revíru Pluskovec
Ondryáš, Daniel
In the observed hunting district the most claimed damages have been caused by browsing and peeling over last five years. We have investigated 11 buck brushes in the 2nd -- 4th age group where level of damage caused by browsing and peeling with red deer was methodically examined and then compared with forestry files. In one of the most damaged buck brush detailed survey of 5 examples of tree trunks was carried out. In these bush brushes we have found out that average damage the amount of 33.45 %, in the forestry files the figure was 13 %. It is out of the question that our data are different from the data of the Czech Forestry Company; so we can suppose that the damages were overlooked or were collected after counting the damages. Average speed of widening the decay of Stereum sanguinoletum was 54.8 cm per year -1 and in horizontal bearing it was 1.82 cm per year -1. Age of hurt was about 10 years.
