Actual state in the 2015 year of the Nun Moth (Lymantria monacha) in the Brdy region
Vondřich, Vladimír ; Šrůtka, Petr (advisor) ; Nakládal, Oto (referee)
This thesis aims to analyze actual state of the nun moth (Lymantria monacha L.) in the Brdy region in the year 2015. The main objective was to determine its population density. For the research several sites were selected in which three monitoring methods were used: adhesive tree bands, dropping method and pheromone-baited traps. The results revealed that the nun moth only occurs in the forest in minimal numbers. Another objective was to evaluate colour forms of moths and determine connection between colour forms of caterpillars and moths. For the lack of captured caterpillars no results were acquired. The majority of moths caught on pheromone-baited traps had gray colouring and relatively small number of moths (21%) had basic (white) colouring.

Stanovení početnosti volně žijících živočichů jako základ mysliveckého a lesnického hospodaření
Plhal, Radim
The results of several studies whose theme was population density of game and the possibility of its estimation were summarized in this paper. Population density is one of the most important characteristics of animal population, especially in relation to the proper sustainable wildlife management. The first study dealt with verification technology of the Game Management Plan for selected ungulate species in the Czech Rep. Further work compared four different methods of counting and the appropriateness of using on the example of wild boar in the forest environment. The following two papers tested the possibility of using the method of dung counting for estimating the numbers of wild boar in the forest environment. Recent work has dealt with the study of the distribution of faeces of wild boar, depending on the different hunting management within two neighbouring hunting grounds. The first study found that the hunting planning in the Czech Republic is not suitable for all ungulate game species. Photo traps could be used to estimate the abundance of wild boar only in combination with other independent methods. Dung counting is a suitable method for estimating the numbers of wild boar. Dung counting could be also used to specify the spatial activity of wild boar in the forest environment.

Ověření početních stavů daňčí zvěře v zájmovém území Trojmezí
Kolář, Petr
This thesis documents the history and current status of fallow deer breeding in the area of interest of the hunters' association of Trojmezí hunting grounds. The work also contains information about the origin of fallow deer population in the area, detailed record of killed and dead animals, including data on their age, weight, trophy value, and photo documentation of trophies and antlers found on the site. The thesis also keeps track of the number of fallow deer in the area since its establishment in 2008 till 2014. Comparison of the data concerning the number of the animals obtained by direct counting by the hunters with the population model based on the population change is also included. The number of fallow deer was verified by counting the faecal pellets on transects in the spring of 2014. The used methods were the FSC method (with no transects cleaning) and the CPM method (with transects cleaning) and the results were statistically evaluated. The FSC method set the fallow deer population density to 4,58+-3,5 animals/km2. The CPM method set the population to 5,52+-5,1 animals/km2. There was no statistically significant variance between the numbers of game set by the mentioned methods. In comparison to the number of animals spotted by the hunters, the method of counting droppings found approximately three times the number of fallow deer. The results are evaluated using charts, graphs and comments.

Occurence and density of corncrake (Crex crex) in selected parts of National Park Šumava in relation to biotope management
PEKSA, Martin
The abundance of males of corncrake (Crex crex) in dependence on its biotope management was studied in the west part of the Šumava National Park. A night counting of singing males of corncrake by the method of point transect was practised. A record of male territorial vocalization was used. The research last from 9th June 2008 to 8th July 2008 in the extent of 598,3 hectare and in the average altitude of 877,7 metres above sea-level. Sixty-two males of corncrake was found out in total. The average population density was 0,07 ex./ha. Among 39 monitored localities there were 53,9 % of perennial biomass crops, 23,8 % of localities without management, 11,9 % of grasslands and 10,5 % of localities where the management according to the agroenvironmental programme is practised. It was acknowledged a positive influence of localities where the management according to the agroenvironmental programme is practised on corncrakes occurrence. In spite of the procentual representation of these localities being the smallest the average occurrence of corncrake there is the largest. It appears from these results that the agroenvironmental programme called "Bird localities on biomass crops - the breeding place of corncrake" is beneficial.
