    From the economical and ecological point of view, beech (Fagus sylvatica L.) is one of the most important forest tree species in Bosnia and Herzegovina. To understand the significance of beech ... forests, something about the structure of forests and forest lands needs to be said. Bosnia and Herzegovina has 3.231.500 hectares of forests and forest land, which is about 60% of its surface. In the forest and forest lands structure, we can see that it has high forest occupying 51.1% of the forest area, coppice occupying 38.70%, shrubs occupying 4%, bare land and clearings occupying 5.80% and other unproductive areas occupying 0.40%. Beech can be found in mixed stands of beech and fir, as well as stands of beech, fir and spruce that occupy 46% of all high forests. Thus, the total area of forests where the beech is found is approximately 1.652.400 hectares. The aim of the study was to carry out the analysis of genetic structures of natural beech populations in Bosnia and Herzegovina by using isoenzyme markers. Conducting a biochemical genetic structure analysis of 14 beech populations, using 10 enzyme systems with 16 isoenzyme gene loci, we found significant differences. Variability in some gene loci is large, while some populations for some gene loci showed monomorphism. The results indicate that in order to maintain natural genetic resources of common beech in Bosnia and Herzegovina, there should be a dense network of gene reserves established. This network from one of the Balkan countriesshould then become a constituent part of all-European network. These gene banks need in situ and ex situ methods (seed banks, seed stands, and seed orchards) to maintain the genetic diversity of populations. Based on the research results, every ecological niche of common beech i.e. their genetic variation should be conserved regarding the appropriate number of populations and individuals to preserve the ecological and physiological features of this valuable commercial species.
