    Beskid Śląski Mountains
    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 aim of the study was to determine the effect of deforestation caused by environmental pollution on the chemical composition of stream waters draining the small catchments located in the Skrzyczne massif (Beskid Śląski, southern Poland). In the 1950−60s this area was subjected to heavy anthropogenic pressure with excessive deposition of sulfur and nitrogen compounds. It resulted in the damage to the stands and deforestation of the ridge fragments of the studied area. The study was conducted in the catchment of the Malinowski Stream and its two subcatchments: forested and deforested in 2013. Waters of the studied streams characterized by low conductivity and mineralization. In the ridge subcatchments they were slightly acidic and in the main catchment – slightly alkaline. In all catchments anions were predominated by sulfates – with the largest in the deforested catchment (31% mval/L). Also nitrates had very large share in the structure of the chemical composition of water, particularly in the forested catchment (15% mval/L). Interestingly, there were low levels of bicarbonates, particularly in the ridge catchments, with their share lower than sulfates and nitrates. Cations in all streams were predominated by calcium. The structure of the chemical composition of water of the Malinowski Stream, expressed by the average share of individual ions was as follows: SO4−HCO3−NO3−Cl−F−Ca−Na−Mg−K−NH4, and in the case of streams draining small ridge catchments: – SO4−NO3−HCO3−Cl−F−Ca−Na−Mg−K−NH4. Conductivity of water decreased together with increased water levels in streams during floods. In the deforested catchment this decrease was more evident. The reaction of nitrate concentration to the increase in water level was however different, as in the stream draining the forested catchment it decreased sharply, while in the deforested catchment it decreased slightly or remained at the similar level. In the dry periods the chemical composition of waters of the examined streams were subject to far less change than during the floods, with the changes of e.g. conductivity being much higher in the stream draining the forested catchment.

    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.

    Opis:
    The study was carried out in the year 2009 on northern, southern and western slopes of Skrzyczne and Głębczański and Roztoczański stream catchments on Barania Góra in the Beskid Śląski Mountains. Water samples were collected from springs during snowmelt (May 1st−3rd). Data set consisting of conductivity, water pH, concentrations of major anions (Cl–, NO3–, SO42–), major cations (Na+, K+, Ca2+, Mg2+) and metals (Al, Fe, Mn, Zn) was produced. Waters were then classified according to Polish standards. Water class depended strongly on chemical composition of melting snow. It was found that water from most sampling points in springs was not potable – 39 out of collected 48 samples on Skrzyczne and 51 out of 57 samples collected on Barania Góra were beyond the first class according to Polish standard from the year 2008. The main reason for that was too low pH and high NO3– concentration. Chemical composition of spring waters depended also on plant cover and local properties of drainage areas. Statistically significant difference was observed between spruce and beech stands. Springs located in beech stands characterised higher concentrations of Ca2+, Mg2+, K+, Na+, SO42–, Cl– and higher PEW and additionally on Barania Góra higher pH as well. This dependence should be considered while planning stand composition in springs neighbourhood.
