    Opis:
    The aim of the present research conducted in the Beskid Śląski was to search for an appropriate, alternative to classic way to regenerate the forest at high mountain altitudes. An attempt was made, therefore, at regeneration of these areas using the group method that imitates the natural formation of spruce biogroups in the forest. It was concluded that the choice of place for planting should entail the time of snow cover disappearance as well as the differentiation of microsites, kind of protection and plant cover. The assessment performed favours the biogroup method of setting up spruce cultures in higher mountain altitudes, especially in areas close to the mountain top.

    Opis:
    The experimental plots were located in the middle forest zone (900– 950 m) on two nappes of the flysch Carpathians: Magura (the Ujsoły Forest District) and Silesian (the Wisła Forest District) in the spruce stands of age class 21– 40 years. Serpentinite was introduced in the autumn of 2008 on all plots while other fertilizers (N, P, NP and NPK) in the spring of 2009. Based on the chemical composition of soil solutions collected in lysimeters placed at the depth of 20 cm in the autumn 2008 and the spring and autumn 2009, ecochemical parameters were calculated: acid neutralization capacity (ANCaq), alkalinity (ALK), the degree of soil acidity (Ma%), acidic cations (Ma), saturation of the exchangeable complex of the soil solid phase (Mb) with alkalis, saturation with alkalis (BS), molar relations Ca/Al, Mb/Al, BC/Al. After the winter, soil solutions became acidic, especially in the Wisła Forest District. The saturation of the studied soils demonstrates moderate flexibility of soils in the Wisła Forest District in relation to acid load, and high flexibility of the Ujsoły soils. The opposite trend was observed for the degree of acidity of soils. Acid neutralization capacity and alkalinity of the waters showed significant variations in soil pH even in the case of small variations in the composition of the solution, if they were caused by the inflow of the anions of NO3 - and SO4 2-. After application of the fertilizers, an increase of Mg, Ca and Mb was noted in the soil solution, determined in the overlaying highly acidic organic horizons trough the ion-exchange buffering mechanism of highly protonated functional groups with high buffering capacity. Highly improved content of Mg in a soil, and in some cases – also the content of N, P and K, present potential improvement of forest growth capacity without the hazard of adverse side-effects of liming. Aluminum stress in the spruce is unlikely, while trees in the control plots in the Wisła Forest District may already be sensitive.

    Opis:
    In autumn 2006, i.e. in the 5th year from the culture establishment, and when the tree growth had finished, on each culture we measured tree height, height increments in the years 2004−2006 and root collar diameters. We also noted the presence of the main shoot and top bud on the main shoot, size and color of the assimilative apparatus and determined the survival rate of the seedlings. The assessed and measured features allowed for determination of the seedling quality and vitality. Mean values of all features were calculated for plots and their groups, distinguished on the basis of their belonging to particular forest districts and regions as well as basing on the presence or absence of stand protection and in regard to stand disintegration. The results indicate the poor condition of parts of the cultures with beech. Generally, the quality and vitality of the seedlings was assessed to be average, with a smaller or larger tendency towards the decrease. This points towards difficulties in performing stand regeneration and in varying their composition in the higher locations of the Beskid Śląski and Żywiecki Mts., which experience extreme climatic conditions. This was observed particularly on height and quality parameters worsened along with an increase in a degree of stand disintegration. Many beech seedlings grew better on the fenced plots than on the unfenced ones, which indicates positive results of the protection of cultures against game and justifies their fencing.
