Jaworzyna Mountain forests of the law have granted protected status as a spa forests and forests in protected zones around the spas, as well as protective forests intakes and sources of water. In addition, forests are located in the Natura 2000 site "Popradzka refuge" and the Poprad Landscape Park. As part of the 24 sample plots laid out. The aim of the study is to determine the effect of runs No. I, II and IV of the ski station Jaworzyna Krynicka SA of the surrounding stand. Performed on them, inter alia, assess damage to trees, an assessment of the X-rays of trees, an assessment of the damage to the tree canopy deciduous beech mainly by Roloff classification It was noticed a significant: change in the number of trees in the areas of research; changes in the species composition; large variation in the abundance of forest stands; increase in X-ray conifer crowns; an increase in damage to the crowns of beech in all areas of research; — inventoried damage is primarily shallow wounds and abrasion bark — wounds on trees can also be a place of infection fungal pathogens; Edges of slopes and point taken for the gondola should be reforested as soon as possible to create a forest edge.
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.
