Scale of anthropic-conditional functional effectiveness (SAPFO – acronym of Czech words) is based on analysis of differences between total real functional potentials of natural and actual tree species composition. Real functional potentials are determined by Quantification and quantitative evaluation of forest functions method. Within SAPFO, differences between partial forest functions are compared, and relations to total functional potential difference are valuated. SAPFO makes possible better formulation of management request to tree species composition. Natural tree species composition and current tree species composition potential functional abilities were studied on the model locality Plešný and Stožec (Šumava National Park, Czech Republic). Tree species mixtures are changing in dependence on forest altitudinal zone (usually with increasing altitude) from forest ecosystems with prevailing beech and admixed Norway spruce to forest ecosystems with prevailing Norway spruce and admixed beech in natural tree species composition. The differences between potentials of forest functions of natural and current tree species composition were determined. Less than 6% of valuated forest stands obtained equal values of real potentials of forest functions in current and natural tree species composition. The differences were higher and most often in ecological-stabilizing forest function (as it was expected).
