This bachelor thesis analyzes the quantification of the forest´s ecosystem services, focusing on the game management. The analysis of the issue begins by looking at the initial attempts to quantify ecosystem services, continues with their nowadays division and moves on to the basic physiological needs of men, which the ecosystems fulfill. The general review gradually narrows down to more detailed passages exploring ecosystem services related to game management. The attention is drawn particularly to the support and production ecosystem services. The Game management methodologies are used to quantify the support services of forest ecosystems, through the relationship of the environment and its carrying capacity for animals, the so-called standardized tribal states. The Forest production services are quantified by calculating the hunting plan. At the end of the thesis, the total value of forest stands is quantified with respect to their theoretical ability to feed one man with venison, for the time resulting from the carrying capacity potential of the given part of the forest. The issue covered in the thesis is related to the most important hunting species of the ungulates, which is red deer, roe deer, wild boar, fallow deer and mouflon. The work is presented in a way which is understandable for a programmer, "uninitiated" to the game management issues, and should serve as a basis for the creation of a computer-aided forest model, which contains the information on the quantification of mentioned ecosystem services. In the final part of the work, the programmer finds algorithmic solution of selected characteristics, using and complementing the SIBYLA program database, as well as flowcharts simplifying the steps of the whole process. The contribution of the work is the possibility to contribute to the development of strategic decision-making of the Slovak forest and hunting management through the growth simulator SIBYLA.
