    Opis:
    Mechanical site preparation (MSP) is commonly used to enable forest regeneration of clear-cuts. Less intense methods may be more suitable from an environmental point of view, but such a method can result in the lack of natural regeneration. We compare the influence of three MSP methods on natural regeneration of Scots pine. The methods differ in their degree of soil disturbance. The effects of MSP by forest plough (FP), active plough (AP), and forest cutter (FC) on density, quality, and biometric parameters of one-year old seedlings were determined. The highest density of seedlings was obtained in the FP treatment (188,000 seedlings ha–1). The seedling density was significantly lower in the AP method (121,000 seedlings ha–1), and in the FC variant (36,000 seedlings ha–1). The best quality seedlings were found in the FC variant, and the worst – in the FP treatment. Most biometric parameters of seedlings did not differ by MSP method, except for the root length and root:shoot ratio. By the end of growing season, in the FP treatment, 1-year old seedlings formed a top bud more than twice as often as the seedlings from the AP and FC treatments. The FP method led to the best Scots pine natural regeneration. The results obtained in the FC variant were not as good as in the FP method, though they were still acceptable from the silvicultural point of view. The FC method was the least intensive method of site preparation, yet it is considered the most appropriate from the environmental (soil protection) point of view.

    Opis:
    Mechanical site preparation is recommended to create optimum conditions for seed germination and seedling growth in a clear−cut area. Lack of soil scarification or less−intense methods may be more suitable from an environmental point of view, but can result in a failure to obtain natural regeneration. This study compared the effects of three mechanical site preparation methods (SPM) characterized by different levels of soil scarification (i.e. double mould−board forest plough (LPz), active plough (PA) or forest mill (FL)), as well as a control variant without mechanical site preparation, on height, density, spatial distribution and survival among naturally regenerating Scots pines (Pinus sylvestris L.) in the first 2 years of growth in a clear−cut area of NE Poland. The experiment was based around a four−block randomized block design involving the four variants. Seedling height was measured at the end of the first and second growing seasons, with measurements performed on 8 meter−wide transects extending across the entire width of the cleat−cut. We found no effect of SPM on seedling height, though the density of seedlings regenerating naturally was found to be dependent. After two years, the highest density was achieved in the PA variant (8.1 seedlings/m2) and the FL variant (7.0 seedlings/m2). A significantly lower density characterized the LPz variant (5.1 seedlings/m2) and the lowest of all the variant without soil scarification (3.2 seedlings/m2). The most homogeneous natural regeneration was achieved following the use of PA (2.6% of 1 m2 plots without seedlings after two growing seasons), while the least homogeneous was the variant without soil scarification (22.4% of 1 m2 plots). Survival of pines after the second growing seasons was quite high (over 80%), and did not differ significantly depending on the SPM. Our research therefore confirmed that, in the absence of mechanical site preparation, natural regeneration of sufficient density and homogeneity cannot be obtained. The best natural regeneration was obtained on sites prepared with PA, and FL scarification being only slightly less favorable. The low density and uneven distribution of seedlings on the soil prepared with LPz was a surprising result. The probable reason for this lay in the high precipitation in the first growing season. On one hand, this provided very good moisture conditions for seed germination and seedling growth on a substrate with high porosity in the PA and FL variants, but on the other the high bulk density of mineral soil in the LPz variant led to oxygen deficit.

    Opis:
    This paper reports on the results of the experiment with pine plantations established in the territory of Pszczyńskie Forests in the moist mixed coniferous (BMw) and moist mixed broadleaved (LMw) forest habitats. The measurements took place in seedlings in the fifth year of growth. The soil preparation variants included: full beds, ridge beds, and strips established with FAO−FAR soil cutter. The parameters subjected to analysis embraced planting density, survival and quality of seedlings, as well as the costs incurred for establishing and tending of plantations taking into consideration soil preparation method. The performance of seedlings planted on full beds was found to be best, while on strips – it was lowest. The seedlings growing on strips showed the best height increment and quality and those growing on beds – the poorest. The variability in parameters between individual sites of the experiment was high.

    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.
