Free living ungulates and field crops
Kamler, Jiří ; Dvořák, J. ; Heroldová, Marta ; Homolka, Miloslav
We evaluated the importance of field crops for the ungulate game species. The large herbivores exploit the field crops at the different intensity according to crop species, season, feeding strategy, human disturbance in the forest etc. The field crops are generally not too important as a food resource for wild ungulate species and in the environment with sufficiency of herb and shrub layer in the forest environment they prefer native diet components.

The natural seasonal changes in the food choice and digestive tract of wild ruminants
Kamler, Jiří ; Homolka, Miloslav
Herbivore populations all over Europe have been strongly influenced by human activities. A combination of harvest, changes in forest structure, supplementary feeding, predator extirpation and others factors have led in most cases to increases of their populations and a severe impact on the composition and structure of the forest vegetation. The food choice of free living ungulate species is strongly influenced by season and animal species and changes in diet composition and quality cause the changes in the digestive tract. Effective management of ungulate populations and forest ecosystems should be based not only on detailed information about the impact of deer browsing and the number of deer to harvest but also on the density of deer species, the food supply, the structure of diets consumed by individual species, attraction and quality of the individual components of food supply the total quality of food taken and seasonal changes in digestive tract.
