Vliv zvěře na stav a vývoj dřevinné vegetace v regionu Týna nad Vltavou
Odehnal, Lukáš
The subject of this diploma was monitoring browsing damage to regeneration of woody plants in hunting area Bečice. Monitoring was made in spring and autumn 2015 on twelve rectangular transects according to the methodolgy of monitoring browsing damage on permanent transects (Čermák, Mrkva, 2003). During this investigation was controlled 3 622 individuals of eight woody plants species. From this species was the dominant sessile oak (Quercus petraea), followed by European beech (Fagus sylvatica) and Norway spruce (Picea abies). The most percentage representation of damage of regeneration (82 %) was fir (Abies alba). At least it was damage Scotss pine (Pinus sylvestris), only 15.24 %. Browsing demage in this region was mostly caused only by roe deer. Results were made in relation to the numbers game, and measures have been proposed hunting and forestry management to reduce negative impacts of ungulate browsing on nature regeneration.

Vliv okusu na přirozenou obnovu a dynamiku lesa v okolí Starého Hrozenkova
Rapant, Jan
The subject of this diploma thesis was monitoring damage of the natural regeneration of trees caused by browsing even-toed ruminant animals near Starý Hrozenkov. The monitoring was carried out in 2013 on fourteen plots of rectangular shape by methodology ČERMÁK, MRKVA (2003). Twelve species of trees have been found, while the most was represented by the beech Fagus sylvatica, followed by sycamore Acer pseudoplatanus and Norway spruce Picea abies. The most damaged tree species was silver birch Betula pendula with damage of 74%, but this tree species made a minimal representation. Ash Fraxinus excelsior was the least damaged tree species -- 22%, Larch and pine were without damage. For the sake of dynamics, the nine plots were measured once again. The growth of sycamore was slowed down.

Evaluation of taste repellents for protection of tree planting stock from deer browsing
Triner, Libor ; Kuneš, Ivan (advisor) ; Kupka, Ivo (referee)
The main goal of this thesis is to assess the efficacy of two repellent products with active ingredients denatonium benzoate and capsaicin to protect the newly established forest tree planting prior to browsing damage by wild game. Repellents were tested on two different experimental plots planted with silver fir (Abies alba). Application of repellents held in three terms and total three times were the damages, which were included in the framework of the six-rating scale, has been detected. The effectiveness of these repellents has been demonstrated already during the second term damage assessments caused by game. During the more than 14-month experiment was damaged almost 2.5 times fewer seedlings treated with repellents based on denatonium benzoate and capsaicin than untreated seedlings, serving as a control. The most common form of damage to the tree was bitten off terminal bud with little scope of additional damage. Damage to seedlings by game differed significantly even within the investigated areas. Use of repellents did not affect the physiological death of seedlings. It was justify the conclusion that most of the damages were caused by roe deer (Capreolus capreolus). Based on several scientific papers on the efficacy of repellent products based on capsaicin and denatonium benzoate was concluded that the main active ingredient in tested repellents is capsaicin.

Protection of the young plantation against the game browsing with use of sheep flees form meat breed and flees breed in area of Železné hory area
Ješátko, Jiří ; Nakládal, Oto (advisor) ; Zeman, Jakub (referee)
This Bachelor paper compares and evaluates the effectiveness of a mechanical protection of forest crops against game browsing by means of using wool from meat-sheep and dairy-sheep breeds. Twenty-one sites were chosen in the Bojanov municipal forest for the use of different types of sheep wool against game browsing. The local growth is dominated by young spruce, with only 10% of other species. Six of these sites were treated with meat-sheep wool, six others with dairy-sheep wool, and the remaining nine sites were treated with both types combined. The primary criterion for evaluation was the damage, through browsing, to the terminal shoot. The extent of the damaged spruce growth in individual localities was regularly monitored in monthly intervals and recorded in a table. Consequently, the data were analyzed and the effectiveness of individual wool types determined through the use of the goodness of fit test. The overall damage caused in the sites treated with meat-sheep and dairy-sheep wool was 1.58 % and 1.77 %, respectively. When applied to the comparison of damage caused in areas treated with meat-sheep and dairy-sheep wool, the goodness of fit test revealed negligible differences, which made it impossible to determine which of the two types of wool is more effective. The quantity of damaged crops in sites treated with both types of wool combined (n=187; chi2=0.37; p=0.53). The quantity of damaged crops in sites treated with meat-sheep wool or dairy-sheep wool only (n=46; chi2=0.15; p=0.69).

Analysis of significant foreign methods for evaluation of game damages to forests
Šafránek, Zbyněk
Game damages to forests are actual and often discussed problem. Evaluation and quantification of these damages in the Czech Republic is legally enshrined in Act No. 449/2001 Coll. about game management and in Decree No. 55/1999 Coll. about method of calculating the amount of injury or damage caused to forests. The aim of this article is to analyze the methods of assessment of damage to forests game in some European countries with similar forestry management like in the Czech republic and comparation with czech legislation.

Possibilities of evaluation and comparison of data obtained from control and comparison plots (CCP) in relation to damages caused by game to forest
Šafránek, Zbyněk ; Matala, Juho
The article deals with the possibilities of evaluation and interpretation of data on game damages in forests which is obtained and collected from control and comparison plots (CCP). Obligation to record the data in young forest stands on the base of control and comparison plots is directed by Act No. 289/1995 Coll., respectively Ministry of Agriculture Decree No. 101/1996 Sb. Each forest owner who has more than 50 hectars of forest has obligation to establish control and comparison plots. System of these plots is composed of two square areas with sides of 5 meters, one of them is fenced, the second is not fenced. At present there is only annual gathering of data, but this data are not further evaluated. This article shows the possibilities of evaluation of this data by the example from the fencing experiment of Finnish Forest Research Institute in the strictly protected natural reserve Pisavaara, Northern Finland.

Possibilities of detection of amount game damages by grazing in artifically established forest stands
Šafránek, Zbyněk
Procedure for determination of input data in areas damaged by game grazing for the purpose of calculating the amount of damage caused by wild game according to Decree no. 55/1999 Coll. is not standardized. The article deals with the possibility of obtaining such input data in a schematic-based forest stands, particularly row plantations. The aim of this paper is to compare the reliability of input data obtained on the basis of counting all individuals on the injured area compared with the counting on the sampling plots - rows. This paper is part of the author's doctoral dissertation titled Standardization of expert detection amount of game damages to the forests.

Pospíšil, Jiří
The aim of this diploma thesis was to assess an influence of game on woody and herbal vegetation in Loučná nad Desnou game preserve. Monitoring was realized in 2014 on 14 monitoring areas according to ČERMÁK, MRKVA (2003) methodics. Total number 3491 individuals of six species were determined in monitoring areas. The most common was European beech Fagus sylvatica, sycamore maple Acer pseudoplatanus and Norway spruce Picea abies. There was also European ash Fraxinus excelsior, small-leaved lime Tilia cordata and silver birch Betula pendula. The most damaged species in natural regeneration was European ash, sycamore maple and small-leaved lime. The influence of game on herbal vegetation was evaluated on the pair organized vegetation reports along the game preserve plot, where the influece of game was visually evident in absence of shrub layer. There was not visible any obvious influence of herbal vegetation on all vegetation reports due to the game.
