Opis:
In the similar soil and climate conditions, the tended and non−tended Scots pine undergrowth of natural origin was equal to the thicket of the same age in terms of the usefulness for cultivation. The non−tended natural regeneration of pine showed the statistically significantly highest mean values of diameter at breast height, height and current annual height increment in comparison with the tended natural and artificial regeneration. The comparison of the morphological parameters of six year old pine seedlings did not reveal statistically significant differences between the soil preparing with the double mould board plough (LPz−75) or the rotary plough. The more frequent silvicultural use of Scots pine natural regeneration, which locally exceeds the artificial regeneration in terms of growth traits and vitality, can diminish the risk of damage to pine stands resulting from suddenly occurring changes in site conditions.

Opis:
The studies were conducted in the years of 1997−2001. The effect of four methods of soil preparation (ploughing with double mouldboard plough LPZ−75, disc plough PTL−2, disc harrowing and ridge formation) on natural regeneration of pine under the canopy shelter was analysed. Significant differences in the density, height and vitality of seedlings in the variant II (ploughing with disc plough) and variant IV (ridge formation) were found in the second and third year of studies. In the following years the differences between the variants were insignificant due to the heavy damage of seedlings caused by the cockchafer larvae. Neither of the methods applied protected the seedlings against this damage.

Opis:
This paper refers to the investigation of the influence of the soil preparation methods and selection of the forest tree species for the forest regeneration on the surface after the forest fire and in case of the poor coniferous forest site types. Results come from the experiment established in 1994 in Notecka Forest according to the split−plots method. Five soil preparation methods were tested (furrows, furrows with subsoiler, subsoiler, full shallow ploughing and control) and six forest tree species (Scots pine, European larch, gray alder, silver birch, pedunculate oak, red oak). On the base of the analysis of variance the height growth and survival of the tested species during 6 year period were evaluated.

Opis:
In this paper the effect of different methods of soil scarification in a clear−cut area were studied. The following soil preparation techniques were applied: the soil cutter, the active soil plough, the traditional method with use of LPz plough, and the manual scarification of soil in circles surrounding the stem of the future young tree. The effect of management of the residual heaps of branches was also tested. Branches were either put in prisms in the original shape or, having been previously chipped, equally distributed over the entire area of the clear−cut. Additional studies focused on the effect of the time of clear−cut execution (winter or summer) on the condition of epigeic carabid communities. The least regressive effect to analysed communities was observed after the application of the point manual soil scarification. The clear−cuts carried out during the winter season, to a greater degree, favours the forest carabid fauna, preserving them in a structure more resembling the forest communities. More distinctive positive effect on the carabids is observed after putting the residual heaps of branches in prisms; the latter gives shelter for the carabid fauna and constitutes the refuge spots for it.

Opis:
The objective of the study was to analyse the density, survival, height and quality of Scots pine (Pinus sylvestris L.) seedlings growing in the furrows and on the ridges. On poor sandy soils (fresh coniferous forest habitat) the performance of seedlings growing on ridges was superior while in a moderately fertile type of mixed coniferous forest habitat where the competition of forest floor vegetation was high, natural regeneration occurred almost entirely in the furrows.

Opis:
The paper reports the performance of pine culture established from natural regeneration in the moist mixed coniferous (BMw), fresh mixed coniferous (BMśw) and moist mixed deciduous (LMw) forest habitats in Pszczyńskie Forests. The seedlings were measured in the successive growing seasons following culture establishment. The soil preparation variants included: full beds, ridge beds, and strips using FAO−FAR soil cutter. The parameters subject to analysis embraced planting density, height and quality of seedlings taking into consideration soil preparation methods. The density of seedlings established on full beds was found to be the best, while on ridge beds – it was the lowest. Seedlings growing on strips showed the best height increment and quality, while those growing on beds – the poorest. The parameter variability between individual sites under the experiment was high.
