Abstract
The idea of sustainable and multifunctional forest management promotes the search for reference of silviculture in natural objects and excluded from management. It is a difficult task due to the large areas of forest, longevity and complexity of forest ecosystems. The presented paper is an example of research using modern statistical and mathematical methods of inventory and periodic control of the forest. The study was performed in the area of 295 ha, strictly protected forests in the Roztocze National Park. The obtained results of research related to the measurement period 1996-2009. They reveal some important information for the practice: (1) in different site conditions can be implemented various species composition of forest stands without disturbing their stability; (2) species structure stands fluctuate over time, and the natural formation of species is an expression of the relationship of current conditions for their development; (3) in the measurement period there was a significant expansion of beech and hornbeam. Opposite trends were observed related to fir and oak; (4) dominance of beech trees in the lowest layer of the forest (90%) may be signal of the future development of natural species-poor, and even solid, beech stands.
