This paper reports results about the regeneration succession on clearings of sessile oak-Turkey oak forests, following successive clear-cut harvesting practice. Phytosociological relevés were taken, according to the space for time substitution model, covering stand ages from 2 to 28 years old. Major steps of the forest regeneration were analysed by multivariate methods and four stages were determined: I = 1-3 years, II = 4-11, III = 12-21(-25) and IV = (22-)26-28 years. Light climate of the four stages were characterised by measuring relative irradiation under clear sky conditions (RI) at four elevations (0, 20, 40 and 80 cm above ground). Herb layer phytomass was studied by the harvesting method in the same stands where RI was determined.Considering statistically significant differences in the studied variables among stages, two main stress periods were distinguished. The most drastic stress event appears during the transition from the mature forest stage to stage I. It is associated with a great and sudden increase in RI at the herb layer level (at 80 cm above ground RI was 95.5%). Also the amount of total herb layer phytomass of stage I increases considerably reaching more than three times higher values than that found under cutting age mature stands.The second stress period occurs in stage III. Significant decline of light intensity occurs during the transition from stage II to III, resulting an RI of 2-2.5%. Herb layer phytomass also becomes significantly reduced in this stage, amounting only 4 g DW/sqm. During this rather unfavourable period the majority of typical sessile oak-Turkey oak species disappear from the stands. A strong correlation between log(RI) and the herb layer aboveground phytomass was also established.The described two stress phases may lead to forest degradation, since the species able to survive the first stress phase with high RI probably cannot tolerate the very low illumination level in stage III. To prevent losses from the flora and vegetation, or at least to mitigate the damage, more frequent thinning in the thin pole phase (stage III) is recommended. Another solution would be the cultivation of uneven-aged forests, with selection cutting or single-tree selection.

Understanding the interrelations between gap size and environmental change, and the effects these have on regeneration processes is a prerequisite for developing techniques of nature-based forestry. The aims of this study were to investigate the effects of gap size on the resulting spatial distributions of key abiotic environmental variables (light and soil moisture) in gaps, and to study how light and soil moisture affect the abundance and distribution of herb layer species. To do this we used eight artificially created gaps - three large (diameter: 35-40 m) and five small (diameter: 10-15 m) - in a mesotrophic submontane beech forest. Data on species' importance and substrate types were collected in systematically distributed 1 m x 1 m quadrats before gap creation and on four occasions during the next two growing seasons. Hemispherical photographs were taken and analysed to estimate relative light intensity. Soil moisture was measured by frequency domain and capacitance probes. It was found that gap size had a profound effect on the environmental variables measured. While relative light intensity values in small gaps did not reach those in large gaps, soil moisture levels did reach similar maximum values in gap centres regardless of gap size. Richness, composition and total cover of herbaceous vegetation were different in small versus large gaps. Much of this difference was attributed to the presence of specific relative light intensities and also to the increased amount of available soil moisture in gaps. Species were differently affected by the combined effects of light and soil moisture, as well as by differences in available substrates. All this resulted in species-specific distribution patterns within gaps.
