Damages caused by wild boars on selected agricultural lands ZD Lipí
EIBL, Jiří
The topic of my work are damages on agricultural land caused by wild boars, reducing game damages, ensuring the standardized state by appropriate hunting and by prevention of the outbreak of swine fever. Today´s agriculture intensively uses oilseed and corn in crop production and in last twenty years the size of sowing plots has expanded several times. Due to these conditions, wild boars are present mainly in these areas, where they can find food and shelter, especially in the period from June to October. This is supported by the fact that in this period the season of mushroom and berry pickers begins and wild boars are disturbed. The care of gamekeepers, who try to attract wild boars from fields and to prevent damage on agricultural land, is devaluated by this. When wild boars are disturbed, they do not like to return to the wood. In the wood they have less and less quiet also because of their mating and expanding. That is why the wild boars have changed from a diurnal animal to a nocturnal animal, living mainly in the fields of oilseed, corn and cereals.

Feeding of wild boar in hunts of Chlum and Sepekov
KOTALÍK, Tomáš
The bachelor thesis is focused on feeding of wild boar in two hunts. The first hunt which was chosen is the hunt of Chlum. The second hunt which was chosen for monitoring is the hunt of Sepekov. There were chosen two feeding places for monitoring in each hunt. The monitoring started in March 2009 and ended in February 2010. The monitoring of feeding should display differences between forest and mixed hunt. But the main reason was to find out the intensity of visits of wild boar in particular seasons pursuant to the influence of different factors. These factors were judged: climatic (snowfall, rainfall and temperature), the influences of sowing and harvest of agricultural crops during the year, the influence of collective hunting on wild boar near the feeding place and shooting on feeding places. The influence of feeding on the damages made by wild boar to fields was judged too. Localities were controlled twice a week. The feeding places were controlled by Ir-C cameras which were given on two feeding places once a week. These facts were found out by the observing. The intensity of visits on the feeding places is very different in particular seasons. The visit rate of feeding places isn´t influenced by the production of forest seeds in spring. We found out that the most favourite feed in this season was maize. Wild boar stays in agricultural monocultures in spring and on feeding places comes minimally. The popularity of particular sorts of feed depends on the term of their putting and hunting of wild boar in autumn and winter. We can avoid the damages to agricultural crops in spring, autumn and winter if we will have large enough forest in which we will be able to hold wild boar by feeding. The visit rate of the feeding place is influenced by the hunting near the feeding place, but the intensity of this influence depends on the scope of the hunting and the number of hunted members of herd which visited this feeding place. Wild boar visits the feeding place about two or three hours earlier in time of indigence. But during the rain it never appears on the feeding place.
