The paper presents a model solution of determination of a functional effects dynamics on forest stands, and a significance of the functional effect in terms of the ecosystem services evaluation. The ecosystem approach to a quantification of forest functions as a base for social utilization of forest benefits and its economic expression are presented. To determine the functional effect – the real effect of forest stands – the method “Quantification and evaluation of all–society forest functions” (VYSKOT et al. 2003) was used. A chronological development of forest stands and their functional effects were modelled on the stands of a certain stand type at one locality in different age class. The research itself was conducted on the territory of forest administration Plešný and Stožec (Šumava National Park, Czech Republic). A combination of value degrees classification and percentage expression of real effects of forest functions seems to be an adequate approach to the evaluation of functional effects of forest stands for decision-making at forest management level. Social requirements for forest benefits cannot be actually (and sustainably) implemented without knowledge of their ecosystem bases (forest functions).
