Beech expanded its area by more than 1,200 ha per year on average. Beech expansion was more pronounced at lower altitudes, on sites with steep topography, and on sites with a higher proportion of beech in potential natural vegetation. The probability of beech expansion reduced by a factor of 0.54 when the distance to the nearest compartment with beech increased by 1 km. During the observed period the growing stock of beech almost doubled. Significant differences were found in changes of beech proportion in the total growing stock among different forest categories.

Environmental variables (bedrock, slope, mean annual temp., site productivity, stoniness of the site) and stand type have statistical significant influence on horizontal distribution ob beech. Beech is most likely to be found in stands at moderate productivity sites on carbonate bedrock with higher slopes and stoniness, in the zone of mean annual temp. 5-10 °C. The density of beech stands is high, high variability of stand densities within stand types is observed. In Slovenia and Europe, further increase of beech proportion and the expansion have been observed over the past few decades.

Research was conducted in two typical Dinaric beech-fir virgin forests: Čorkova Uvala (Croatia) and Rajhenavski Rog (Slovenia). In Rajhenavski Rog we established extremely poor regeneration of the silver fir, while beech regenerated considerably better. The very poor regeneration of the fir in Rajhenavski Rog is the consequence of excessive number of game, as compared to the Čorkova Uvala virgin forest. The much better regeneration of the beech in Rajhenavski Rog is caused by the higher level of light upon the larger areas of the canopy gaps, which is the result of the fir dieback.

This paper analyses the quality of beech stands on sites classified into Isopyro-Fagetum association. Analysis showed rather high frequency of stem defects, low situated covered knot on tree stems, frequent red heartwood appearance and consequently an unfavorable assortment structure. The normal type prevails among the red heartwood types and it is followed by the abnormaltype. Rottenness occurs often as well.

An overview of modern concepts in beech tending is presented, describing the models, developed in Central Europe; i.e. Swiss tending model with around 150 crop trees per ha, German tending model with around 100 crop trees per ha, and German and French tending models with maximum number of 80 crop trees per ha. We suggest earlier selection of lower number of crop trees with moderate thinning in the first part of the production period, timely formation and maintenance of the crown, the reduction of the production period and usage of versatile regeneration and silvicultural techniques.
